Beispiele

Das folgende Codebeispiel zeigt, wie zwei zugeordnete Arrays sortiert werden, wobei das erste Array die Schlüssel enthält und das zweite Array die Werte enthält. Sortierungen erfolgen mithilfe des Standardabgleichs und eines benutzerdefinierten Vergleichs, der die Sortierreihenfolge umkehrt. Beachten Sie, dass das Ergebnis je nach aktuellem CultureInfovariieren kann.

Hinweise

Jeder Schlüssel in der keysArray verfügt über ein entsprechendes Element im itemsArray. Wenn ein Schlüssel während der Sortierung neu positioniert wird, wird das entsprechende Element im itemsArray entsprechend neu positioniert. Daher wird die itemsArray nach der Anordnung der entsprechenden Schlüssel im keysArraysortiert.

Wenn comparernullist, muss jeder Schlüssel innerhalb des angegebenen Elementbereichs in der keysArray die IComparable Schnittstelle implementieren, um Vergleiche mit jedem anderen Schlüssel zu ermöglichen.

Sie können sortieren, wenn mehr Elemente als Schlüssel vorhanden sind, aber die Elemente ohne entsprechende Schlüssel werden nicht sortiert. Sie können nicht sortieren, wenn mehr Schlüssel als Elemente vorhanden sind. Dadurch wird ein ArgumentExceptionausgelöst.

Wenn die Sortierung nicht erfolgreich abgeschlossen wurde, sind die Ergebnisse nicht definiert.

.NET enthält vordefinierte IComparer Implementierungen, die in der folgenden Tabelle aufgeführt sind.

Sie können auch benutzerdefinierte Vergleiche unterstützen, indem Sie eine Instanz Ihrer eigenen IComparer Implementierung für den parameter comparer bereitstellen. In diesem Beispiel wird eine benutzerdefinierte IComparer Implementierung definiert, die die Standardsortierreihenfolge umkehrt und einen Vergleich zwischen Zeichenfolgen ohne Groß-/Kleinschreibung durchführt.

Diese Methode verwendet den Algorithmus für die introspektive Sortierung (introsorten) wie folgt:

• Wenn die Partitionsgröße kleiner oder gleich 16 Elemente ist, verwendet sie eine Einfügesortierung Algorithmus.

• Wenn die Anzahl der Partitionen 2 * Log^Nüberschreitet, wobei N der Bereich des Eingabearrays ist, wird ein Heapsort Algorithmus verwendet.

• Andernfalls wird ein Quicksort- Algorithmus verwendet.

Diese Implementierung führt eine instabile Sortierung durch; wenn zwei Elemente gleich sind, wird ihre Reihenfolge möglicherweise nicht beibehalten. Im Gegensatz dazu behält eine stabile Sortierung die Reihenfolge von Elementen bei, die gleich sind.

Diese Methode ist ein O(n Protokoll n) Vorgang, wobei nlengthist.

Hinweise für Aufrufer

.NET Framework 4 und frühere Versionen verwendeten nur den Quicksort-Algorithmus. Quicksort identifiziert ungültige Vergleiche in einigen Situationen, in denen der Sortiervorgang eine IndexOutOfRangeException Ausnahme auslöst, und löst eine ArgumentException Ausnahme für den Aufrufer aus. Ab .NET Framework 4.5 ist es möglich, dass Sortiervorgänge, die zuvor ArgumentException ausgelöst haben, keine Ausnahme auslösen, da die Einfügesortierungs- und Heapsortalgorithmen keinen ungültigen Vergleich erkennen. Dies gilt größtenteils für Arrays mit weniger als oder gleich 16 Elementen.

Hinweise

Wenn comparernullist, muss jedes Element innerhalb des angegebenen Elementbereichs in array die IComparable Schnittstelle implementieren, um Vergleiche mit jedem anderen Element in arrayzu ermöglichen.

Wenn die Sortierung nicht erfolgreich abgeschlossen wurde, sind die Ergebnisse nicht definiert.

.NET enthält vordefinierte IComparer Implementierungen, die in der folgenden Tabelle aufgeführt sind.

Sie können auch benutzerdefinierte Vergleiche unterstützen, indem Sie eine Instanz Ihrer eigenen IComparer Implementierung für den parameter comparer bereitstellen. In diesem Beispiel wird eine ReverseComparer Klasse definiert, die die Standardsortierreihenfolge für Instanzen eines Typs umkehrt und einen Vergleich zwischen Zeichenfolgen ohne Groß-/Kleinschreibung durchführt.

Diese Methode verwendet den Algorithmus für die introspektive Sortierung (introsorten) wie folgt:

• Wenn die Partitionsgröße kleiner oder gleich 16 Elemente ist, verwendet sie eine Einfügesortierung Algorithmus.

• Wenn die Anzahl der Partitionen 2 * Log^Nüberschreitet, wobei N der Bereich des Eingabearrays ist, wird ein Heapsort Algorithmus verwendet.

• Andernfalls wird ein Quicksort- Algorithmus verwendet.

Diese Implementierung führt eine instabile Sortierung durch; wenn zwei Elemente gleich sind, wird ihre Reihenfolge möglicherweise nicht beibehalten. Im Gegensatz dazu behält eine stabile Sortierung die Reihenfolge von Elementen bei, die gleich sind.

Diese Methode ist ein O(n Protokoll n) Vorgang, wobei nlengthist.

Hinweise für Aufrufer

.NET Framework 4 und frühere Versionen verwendeten nur den Quicksort-Algorithmus. Quicksort identifiziert ungültige Vergleiche in einigen Situationen, in denen der Sortiervorgang eine IndexOutOfRangeException Ausnahme auslöst, und löst eine ArgumentException Ausnahme für den Aufrufer aus. Ab .NET Framework 4.5 ist es möglich, dass Sortiervorgänge, die zuvor ArgumentException ausgelöst haben, keine Ausnahme auslösen, da die Einfügesortierungs- und Heapsortalgorithmen keinen ungültigen Vergleich erkennen. Dies gilt größtenteils für Arrays mit weniger als oder gleich 16 Elementen.

Beispiele

Das folgende Codebeispiel zeigt, wie zwei zugeordnete Arrays sortiert werden, wobei das erste Array die Schlüssel enthält und das zweite Array die Werte enthält. Sortierungen erfolgen mithilfe des Standardabgleichs und eines benutzerdefinierten Vergleichs, der die Sortierreihenfolge umkehrt. Beachten Sie, dass das Ergebnis je nach aktuellem CultureInfovariieren kann.

Hinweise

Jeder Schlüssel in der keysArray verfügt über ein entsprechendes Element im itemsArray. Wenn ein Schlüssel während der Sortierung neu positioniert wird, wird das entsprechende Element im itemsArray entsprechend neu positioniert. Daher wird die itemsArray nach der Anordnung der entsprechenden Schlüssel im keysArraysortiert.

Jeder Schlüssel innerhalb des angegebenen Elementbereichs in der keysArray muss die IComparable Schnittstelle implementieren, um Vergleiche mit jedem anderen Schlüssel zu ermöglichen.

Sie können sortieren, wenn mehr Elemente als Schlüssel vorhanden sind, aber die Elemente ohne entsprechende Schlüssel werden nicht sortiert. Sie können nicht sortieren, wenn mehr Schlüssel als Elemente vorhanden sind. Dadurch wird ein ArgumentExceptionausgelöst.

Wenn die Sortierung nicht erfolgreich abgeschlossen wurde, sind die Ergebnisse nicht definiert.

Diese Methode verwendet den Algorithmus für die introspektive Sortierung (introsorten) wie folgt:

• Wenn die Partitionsgröße kleiner oder gleich 16 Elemente ist, verwendet sie eine Einfügesortierung Algorithmus.

• Wenn die Anzahl der Partitionen 2 * Log^Nüberschreitet, wobei N der Bereich des Eingabearrays ist, wird ein Heapsort Algorithmus verwendet.

• Andernfalls wird ein Quicksort- Algorithmus verwendet.

Diese Implementierung führt eine instabile Sortierung durch; wenn zwei Elemente gleich sind, wird ihre Reihenfolge möglicherweise nicht beibehalten. Im Gegensatz dazu behält eine stabile Sortierung die Reihenfolge von Elementen bei, die gleich sind.

Diese Methode ist ein O(n Protokoll n) Vorgang, wobei nlengthist.

Hinweise

Jeder Schlüssel in der keysArray verfügt über ein entsprechendes Element im itemsArray. Wenn ein Schlüssel während der Sortierung neu positioniert wird, wird das entsprechende Element im itemsArray entsprechend neu positioniert. Daher wird die itemsArray nach der Anordnung der entsprechenden Schlüssel im keysArraysortiert.

Wenn comparernullist, muss jeder Schlüssel in der keysArray die IComparable Schnittstelle implementieren, um Vergleiche mit jedem anderen Schlüssel durchführen zu können.

Sie können sortieren, wenn mehr Elemente als Schlüssel vorhanden sind, aber die Elemente ohne entsprechende Schlüssel werden nicht sortiert. Sie können nicht sortieren, wenn mehr Schlüssel als Elemente vorhanden sind. Dadurch wird ein ArgumentExceptionausgelöst.

Wenn die Sortierung nicht erfolgreich abgeschlossen wurde, sind die Ergebnisse nicht definiert.

.NET enthält vordefinierte IComparer Implementierungen, die in der folgenden Tabelle aufgeführt sind.

Sie können auch benutzerdefinierte Vergleiche unterstützen, indem Sie eine Instanz Ihrer eigenen IComparer Implementierung für den parameter comparer bereitstellen. In diesem Beispiel wird eine IComparer Implementierung definiert, die die Standardsortierreihenfolge umkehrt und einen Vergleich zwischen Zeichenfolgen ohne Groß-/Kleinschreibung durchführt.

Diese Methode verwendet den Algorithmus für die introspektive Sortierung (introsorten) wie folgt:

• Wenn die Partitionsgröße kleiner oder gleich 16 Elemente ist, verwendet sie eine Einfügesortierung Algorithmus.

• Wenn die Anzahl der Partitionen 2 * Log^Nüberschreitet, wobei N der Bereich des Eingabearrays ist, wird ein Heapsort Algorithmus verwendet.

• Andernfalls wird ein Quicksort- Algorithmus verwendet.

Diese Implementierung führt eine instabile Sortierung durch; wenn zwei Elemente gleich sind, wird ihre Reihenfolge möglicherweise nicht beibehalten. Im Gegensatz dazu behält eine stabile Sortierung die Reihenfolge von Elementen bei, die gleich sind.

Diese Methode ist ein O(n Protokoll n) Vorgang, wobei n die Length von keysist.

Hinweise für Aufrufer

.NET Framework 4 und frühere Versionen verwendeten nur den Quicksort-Algorithmus. Quicksort identifiziert ungültige Vergleiche in einigen Situationen, in denen der Sortiervorgang eine IndexOutOfRangeException Ausnahme auslöst, und löst eine ArgumentException Ausnahme für den Aufrufer aus. Ab .NET Framework 4.5 ist es möglich, dass Sortiervorgänge, die zuvor ArgumentException ausgelöst haben, keine Ausnahme auslösen, da die Einfügesortierungs- und Heapsortalgorithmen keinen ungültigen Vergleich erkennen. Dies gilt größtenteils für Arrays mit weniger als oder gleich 16 Elementen.

Beispiele

Das folgende Beispiel zeigt, wie zwei zugeordnete Arrays sortiert werden, bei denen das erste Array die Schlüssel enthält und das zweite Array die Werte enthält. Sortierungen erfolgen mithilfe des Standardabgleichs und eines benutzerdefinierten Vergleichs, der die Sortierreihenfolge umkehrt. Beachten Sie, dass das Ergebnis je nach aktuellem CultureInfovariieren kann.

Hinweise

Jeder Schlüssel in der keysArray verfügt über ein entsprechendes Element im itemsArray. Wenn ein Schlüssel während der Sortierung neu positioniert wird, wird das entsprechende Element im itemsArray entsprechend neu positioniert. Daher wird die itemsArray nach der Anordnung der entsprechenden Schlüssel im keysArraysortiert.

Jeder Schlüssel in der keysArray muss die IComparable Schnittstelle implementieren, um Vergleiche mit jedem anderen Schlüssel durchführen zu können.

Sie können sortieren, wenn mehr Elemente als Schlüssel vorhanden sind, aber die Elemente ohne entsprechende Schlüssel werden nicht sortiert. Sie können nicht sortieren, wenn mehr Schlüssel als Elemente vorhanden sind. Dadurch wird ein ArgumentExceptionausgelöst.

Wenn die Sortierung nicht erfolgreich abgeschlossen wurde, sind die Ergebnisse nicht definiert.

Diese Methode verwendet den Algorithmus für die introspektive Sortierung (introsorten) wie folgt:

• Wenn die Partitionsgröße kleiner oder gleich 16 Elemente ist, verwendet sie eine Einfügesortierung Algorithmus.

• Wenn die Anzahl der Partitionen 2 * Log^Nüberschreitet, wobei N der Bereich des Eingabearrays ist, wird ein Heapsort Algorithmus verwendet.

• Andernfalls wird ein Quicksort- Algorithmus verwendet.

Diese Implementierung führt eine instabile Sortierung durch; wenn zwei Elemente gleich sind, wird ihre Reihenfolge möglicherweise nicht beibehalten. Im Gegensatz dazu behält eine stabile Sortierung die Reihenfolge von Elementen bei, die gleich sind.

Diese Methode ist ein O(n Protokoll n) Vorgang, wobei n die Length von keysist.

Hinweise

Wenn comparernullist, muss jedes Element von array die IComparable Schnittstelle implementieren, um Vergleiche mit jedem anderen Element in arrayzu erhalten.

Wenn die Sortierung nicht erfolgreich abgeschlossen wurde, sind die Ergebnisse nicht definiert.

Diese Methode verwendet den Algorithmus für die introspektive Sortierung (introsorten) wie folgt:

• Wenn die Partitionsgröße kleiner oder gleich 16 Elemente ist, verwendet sie eine Einfügesortierung Algorithmus.

• Wenn die Anzahl der Partitionen 2 * Log^Nüberschreitet, wobei N der Bereich des Eingabearrays ist, wird ein Heapsort Algorithmus verwendet.

• Andernfalls wird ein Quicksort- Algorithmus verwendet.

Diese Implementierung führt eine instabile Sortierung durch; wenn zwei Elemente gleich sind, wird ihre Reihenfolge möglicherweise nicht beibehalten. Im Gegensatz dazu behält eine stabile Sortierung die Reihenfolge von Elementen bei, die gleich sind.

Diese Methode ist ein O(n Protokoll n) Vorgang, wobei n die Length von arrayist.

.NET enthält vordefinierte IComparer Implementierungen, die in der folgenden Tabelle aufgeführt sind.

Sie können auch benutzerdefinierte Vergleiche unterstützen, indem Sie eine Instanz Ihrer eigenen IComparer Implementierung für den parameter comparer bereitstellen. In diesem Beispiel wird eine ReverseComparer Klasse definiert, die die Standardsortierreihenfolge für Instanzen eines Typs umkehrt und einen Vergleich zwischen Zeichenfolgen ohne Groß-/Kleinschreibung durchführt.

Hinweise für Aufrufer

.NET Framework 4 und frühere Versionen verwendeten nur den Quicksort-Algorithmus. Quicksort identifiziert ungültige Vergleiche in einigen Situationen, in denen der Sortiervorgang eine IndexOutOfRangeException Ausnahme auslöst, und löst eine ArgumentException Ausnahme für den Aufrufer aus. Ab .NET Framework 4.5 ist es möglich, dass Sortiervorgänge, die zuvor ArgumentException ausgelöst haben, keine Ausnahme auslösen, da die Einfügesortierungs- und Heapsortalgorithmen keinen ungültigen Vergleich erkennen. Dies gilt größtenteils für Arrays mit weniger als oder gleich 16 Elementen.

Beispiele

Im folgenden Codebeispiel wird die Sort<T>(T[]) generische Methodenüberladung und die BinarySearch<T>(T[], T) generische Methodenüberladung veranschaulicht. Ein Array von Zeichenfolgen wird in keiner bestimmten Reihenfolge erstellt.

Das Array wird angezeigt, sortiert und erneut angezeigt.

Die BinarySearch<T>(T[], T) generische Methodenüberladung wird dann verwendet, um nach zwei Zeichenfolgen zu suchen, eines, das nicht im Array enthalten ist und eines, das heißt. Das Array und der Rückgabewert der BinarySearch-Methode werden an die ShowWhere generische Methode übergeben, die den Indexwert anzeigt, wenn die Zeichenfolge gefunden wird, und andernfalls fallen die Elemente, zwischen denen die Suchzeichenfolge fallen würde, wenn sie sich im Array befand. The index is negative if the string is not n the array, so the ShowWhere method takes the bitwise complement (the ~ operator in C# and Visual C++, Xor -1 in Visual Basic) to obtain the index of the first element in the list that is larger than the search string.

Hinweise

Jedes Element von array muss die IComparable<T> generische Schnittstelle implementieren, um Vergleiche mit jedem anderen Element in arrayzu erhalten.

Wenn die Sortierung nicht erfolgreich abgeschlossen wurde, sind die Ergebnisse nicht definiert.

Diese Methode verwendet den Algorithmus für die introspektive Sortierung (introsorten) wie folgt:

• Wenn die Partitionsgröße kleiner oder gleich 16 Elemente ist, verwendet sie eine Einfügesortierung Algorithmus.

• Wenn die Anzahl der Partitionen 2 * Log^Nüberschreitet, wobei N der Bereich des Eingabearrays ist, wird ein Heapsort Algorithmus verwendet.

• Andernfalls wird ein Quicksort- Algorithmus verwendet.

Diese Implementierung führt eine instabile Sortierung durch; wenn zwei Elemente gleich sind, wird ihre Reihenfolge möglicherweise nicht beibehalten. Im Gegensatz dazu behält eine stabile Sortierung die Reihenfolge von Elementen bei, die gleich sind.

Diese Methode ist ein O(n Protokoll n) Vorgang, wobei n die Length von arrayist.

Beispiele

Im folgenden Codebeispiel wird die Sort<T>(T[], IComparer<T>) generische Methodenüberladung und die BinarySearch<T>(T[], T, IComparer<T>) generische Methodenüberladung veranschaulicht.

Im Codebeispiel wird ein alternativer Vergleich für Zeichenfolgen mit dem Namen ReverseComparedefiniert, der die generische Schnittstelle IComparer<string> (IComparer(Of String) in Visual Basic, IComparer<String^> in Visual C++) implementiert. Der Comparer ruft die CompareTo(String)-Methode auf, wobei die Reihenfolge der Vergleiche umgekehrt wird, sodass die Zeichenfolgen anstelle von "niedrig" von "hoch" nach "hoch" sortieren.

Das Array wird angezeigt, sortiert und erneut angezeigt. Arrays müssen sortiert werden, um die BinarySearch-Methode zu verwenden.

Die BinarySearch<T>(T[], T, IComparer<T>) generische Methodenüberladung wird dann verwendet, um nach zwei Zeichenfolgen zu suchen, eines, das nicht im Array enthalten ist und eines, das heißt. Das Array und der Rückgabewert der BinarySearch<T>(T[], T, IComparer<T>)-Methode werden an die ShowWhere generische Methode übergeben, die den Indexwert anzeigt, wenn die Zeichenfolge gefunden wird, und andernfalls fallen die Elemente, zwischen denen die Suchzeichenfolge fallen würde, wenn sie sich im Array befand. The index is negative if the string is not n the array, so the ShowWhere method takes the bitwise complement (the ~ operator in C# and Visual C++, Xor -1 in Visual Basic) to obtain the index of the first element in the list that is larger than the search string.

Hinweise für Aufrufer

.NET Framework 4 und frühere Versionen verwendeten nur den Quicksort-Algorithmus. Quicksort identifiziert ungültige Vergleiche in einigen Situationen, in denen der Sortiervorgang eine IndexOutOfRangeException Ausnahme auslöst, und löst eine ArgumentException Ausnahme für den Aufrufer aus. Ab .NET Framework 4.5 ist es möglich, dass Sortiervorgänge, die zuvor ArgumentException ausgelöst haben, keine Ausnahme auslösen, da die Einfügesortierungs- und Heapsortalgorithmen keinen ungültigen Vergleich erkennen. Dies gilt größtenteils für Arrays mit weniger als oder gleich 16 Elementen.

Im folgenden Codebeispiel wird die Sort(Comparison<T>) Methodenüberladung veranschaulicht.

Im Codebeispiel wird eine alternative Vergleichsmethode für Zeichenfolgen mit dem Namen CompareDinosByLengthdefiniert. Diese Methode funktioniert wie folgt: Zunächst werden die Comparands aufnullgetestet, und ein Nullverweis wird als kleiner als ein Nicht-Null-Wert behandelt. Zweitens werden die Zeichenfolgenlängen verglichen, und die längere Zeichenfolge gilt als größer. Drittens wird der normale Zeichenfolgenvergleich verwendet, wenn die Längen gleich sind.

Ein Array von Zeichenfolgen wird erstellt und mit vier Zeichenfolgen in keiner bestimmten Reihenfolge aufgefüllt. Die Liste enthält auch eine leere Zeichenfolge und einen Nullverweis. Die Liste wird angezeigt, sortiert mit einem Comparison<T> generischen Delegaten, der die CompareDinosByLength Methode darstellt, und erneut angezeigt.

Hinweise

Wenn die Sortierung nicht erfolgreich abgeschlossen wurde, sind die Ergebnisse nicht definiert.

Diese Methode verwendet den Algorithmus für die introspektive Sortierung (introsorten) wie folgt:

• Wenn die Partitionsgröße kleiner oder gleich 16 Elemente ist, verwendet sie eine Einfügesortierung Algorithmus.

• Wenn die Anzahl der Partitionen 2 * Log^Nüberschreitet, wobei N der Bereich des Eingabearrays ist, wird ein Heapsort Algorithmus verwendet.

• Andernfalls wird ein Quicksort- Algorithmus verwendet.

Diese Implementierung führt eine instabile Sortierung durch; wenn zwei Elemente gleich sind, wird ihre Reihenfolge möglicherweise nicht beibehalten. Im Gegensatz dazu behält eine stabile Sortierung die Reihenfolge von Elementen bei, die gleich sind.

Diese Methode ist ein O(n Protokoll n) Vorgang, wobei n die Length von arrayist.

Hinweise für Aufrufer

.NET Framework 4 und frühere Versionen verwendeten nur den Quicksort-Algorithmus. Quicksort identifiziert ungültige Vergleiche in einigen Situationen, in denen der Sortiervorgang eine IndexOutOfRangeException Ausnahme auslöst, und löst eine ArgumentException Ausnahme für den Aufrufer aus. Ab .NET Framework 4.5 ist es möglich, dass Sortiervorgänge, die zuvor ArgumentException ausgelöst haben, keine Ausnahme auslösen, da die Einfügesortierungs- und Heapsortalgorithmen keinen ungültigen Vergleich erkennen. Dies gilt größtenteils für Arrays mit weniger als oder gleich 6 Elementen.

Beispiele

Im folgenden Codebeispiel wird die Sort<T>(T[], Int32, Int32) generische Methodenüberladung und die Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32, IComparer<TKey>) generische Methodenüberladung zum Sortieren eines Bereichs in einem Array veranschaulicht.

Im Codebeispiel wird ein alternativer Vergleich für Zeichenfolgen mit dem Namen ReverseComparedefiniert, der die generische Schnittstelle IComparer<string> (IComparer(Of String) in Visual Basic, IComparer<String^> in Visual C++) implementiert. Der Comparer ruft die CompareTo(String)-Methode auf, wobei die Reihenfolge der Vergleiche umgekehrt wird, sodass die Zeichenfolgen anstelle von "niedrig" von "hoch" nach "hoch" sortieren.

Das Codebeispiel erstellt und zeigt ein Array von Dinosauriernamen an, bestehend aus drei Herbivoren gefolgt von drei Karnivoren (Tyrannosauriden, um genau zu sein). Die Sort<T>(T[], Int32, Int32) generische Methodenüberladung wird verwendet, um die letzten drei Elemente des Arrays zu sortieren, die dann angezeigt wird. Die Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32, IComparer<TKey>) generische Methodenüberladung wird mit ReverseCompare verwendet, um die letzten drei Elemente in umgekehrter Reihenfolge zu sortieren. Die gründlich verwechselten Dinosaurier werden wieder angezeigt.

Hinweise

Wenn comparernullist, muss jedes Element innerhalb des angegebenen Elementbereichs in array die IComparable<T> generische Schnittstelle implementieren, um Vergleiche mit jedem anderen Element in arrayzu ermöglichen.

Wenn die Sortierung nicht erfolgreich abgeschlossen wurde, sind die Ergebnisse nicht definiert.

Diese Methode verwendet den Algorithmus für die introspektive Sortierung (introsorten) wie folgt:

• Wenn die Partitionsgröße kleiner oder gleich 16 Elemente ist, verwendet sie eine Einfügesortierung Algorithmus.

• Wenn die Anzahl der Partitionen 2 * Log^Nüberschreitet, wobei N der Bereich des Eingabearrays ist, wird ein Heapsort Algorithmus verwendet.

• Andernfalls wird ein Quicksort- Algorithmus verwendet.

Diese Implementierung führt eine instabile Sortierung durch; wenn zwei Elemente gleich sind, wird ihre Reihenfolge möglicherweise nicht beibehalten. Im Gegensatz dazu behält eine stabile Sortierung die Reihenfolge von Elementen bei, die gleich sind.

Diese Methode ist ein O(n Protokoll n) Vorgang, wobei nlengthist.

Hinweise für Aufrufer

.NET Framework 4 und frühere Versionen verwendeten nur den Quicksort-Algorithmus. Quicksort identifiziert ungültige Vergleiche in einigen Situationen, in denen der Sortiervorgang eine IndexOutOfRangeException Ausnahme auslöst, und löst eine ArgumentException Ausnahme für den Aufrufer aus. Ab .NET Framework 4.5 ist es möglich, dass Sortiervorgänge, die zuvor ArgumentException ausgelöst haben, keine Ausnahme auslösen, da die Einfügesortierungs- und Heapsortalgorithmen keinen ungültigen Vergleich erkennen. Dies gilt größtenteils für Arrays mit weniger als oder gleich 16 Elementen.

Beispiele

Das folgende Codebeispiel veranschaulicht die Sort<TKey,TValue>(TKey[], TValue[]), Sort<TKey,TValue>(TKey[], TValue[], IComparer<TKey>), Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32)und Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32, IComparer<TKey>) generische Methodenüberladungen zum Sortieren von Arrays, die Schlüssel und Werte darstellen.

Im Codebeispiel wird ein alternativer Vergleich für Zeichenfolgen namens ReverseComparedefiniert, der die generische Schnittstelle IComparer<string>(IComparer(Of String) in Visual Basic, IComparer<String^> in Visual C++) implementiert. Der Comparer ruft die CompareTo(String)-Methode auf, wobei die Reihenfolge der Vergleiche umgekehrt wird, sodass die Zeichenfolgen anstelle von "niedrig" von "hoch" nach "hoch" sortieren.

Das Codebeispiel erstellt und zeigt ein Array von Dinosauriernamen (die Schlüssel) und ein Array von ganzen Zahlen an, die die maximale Länge jedes Dinosauriers in Metern (die Werte) darstellen. Die Arrays werden dann mehrmals sortiert und angezeigt:

• Die Sort<TKey,TValue>(TKey[], TValue[]) Überladung wird verwendet, um beide Arrays in der Reihenfolge der Dinosauriernamen im ersten Array zu sortieren.

• Die Sort<TKey,TValue>(TKey[], TValue[], IComparer<TKey>) Überladung und eine Instanz von ReverseCompare werden verwendet, um die Sortierreihenfolge der gekoppelten Arrays umzukehren.

• Die Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32) Überladung wird verwendet, um die letzten drei Elemente beider Arrays zu sortieren.

• Die Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32, IComparer<TKey>) Überladung wird verwendet, um die letzten drei Elemente beider Arrays in umgekehrter Reihenfolge zu sortieren.

Hinweise

Jeder Schlüssel in der keysArray verfügt über ein entsprechendes Element im itemsArray. Wenn ein Schlüssel während der Sortierung neu positioniert wird, wird das entsprechende Element im itemsArray entsprechend neu positioniert. Daher wird die itemsArray nach der Anordnung der entsprechenden Schlüssel im keysArraysortiert.

Wenn comparernullist, muss jeder Schlüssel innerhalb des angegebenen Elementbereichs in der keysArray die IComparable<T> generische Schnittstelle implementieren, um Vergleiche mit jedem anderen Schlüssel zu ermöglichen.

Sie können sortieren, wenn mehr Elemente als Schlüssel vorhanden sind, aber die Elemente ohne entsprechende Schlüssel werden nicht sortiert. Sie können nicht sortieren, wenn mehr Schlüssel als Elemente vorhanden sind. Dadurch wird ein ArgumentExceptionausgelöst.

Wenn die Sortierung nicht erfolgreich abgeschlossen wurde, sind die Ergebnisse nicht definiert.

Diese Methode verwendet den introspektiven Sortieralgorithmus (Introsort) wie folgt:

• Wenn die Partitionsgröße kleiner oder gleich 16 Elemente ist, verwendet sie eine Einfügesortierung Algorithmus.

• Wenn die Anzahl der Partitionen 2 * Log^Nüberschreitet, wobei N der Bereich des Eingabearrays ist, wird ein Heapsort Algorithmus verwendet.

• Andernfalls wird ein Quicksort- Algorithmus verwendet.

Diese Implementierung führt eine instabile Sortierung durch; wenn zwei Elemente gleich sind, wird ihre Reihenfolge möglicherweise nicht beibehalten. Im Gegensatz dazu behält eine stabile Sortierung die Reihenfolge von Elementen bei, die gleich sind.

Diese Methode ist ein O(n Protokoll n) Vorgang, wobei nlengthist.

Hinweise für Aufrufer

.NET Framework 4 und frühere Versionen verwendeten nur den Quicksort-Algorithmus. Quicksort identifiziert ungültige Vergleiche in einigen Situationen, in denen der Sortiervorgang eine IndexOutOfRangeException Ausnahme auslöst, und löst eine ArgumentException Ausnahme für den Aufrufer aus. Ab .NET Framework 4.5 ist es möglich, dass Sortiervorgänge, die zuvor ArgumentException ausgelöst haben, keine Ausnahme auslösen, da die Einfügesortierungs- und Heapsortalgorithmen keinen ungültigen Vergleich erkennen. Dies gilt größtenteils für Arrays mit weniger als oder gleich 16 Elementen.

Beispiele

Das folgende Codebeispiel veranschaulicht die Sort<TKey,TValue>(TKey[], TValue[]), Sort<TKey,TValue>(TKey[], TValue[], IComparer<TKey>), Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32)und Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32, IComparer<TKey>) generische Methodenüberladungen zum Sortieren von Arrays, die Schlüssel und Werte darstellen.

Im Codebeispiel wird ein alternativer Vergleich für Zeichenfolgen mit dem Namen ReverseComparedefiniert, der die generische Schnittstelle IComparer<string> (IComparer(Of String) in Visual Basic, IComparer<String^> in Visual C++) implementiert. Der Comparer ruft die CompareTo(String)-Methode auf, wobei die Reihenfolge der Vergleiche umgekehrt wird, sodass die Zeichenfolgen anstelle von "niedrig" von "hoch" nach "hoch" sortieren.

Das Codebeispiel erstellt und zeigt ein Array von Dinosauriernamen (die Schlüssel) und ein Array von ganzen Zahlen an, die die maximale Länge jedes Dinosauriers in Metern (die Werte) darstellen. Die Arrays werden dann mehrmals sortiert und angezeigt:

• Die Sort<TKey,TValue>(TKey[], TValue[]) Überladung wird verwendet, um beide Arrays in der Reihenfolge der Dinosauriernamen im ersten Array zu sortieren.

• Die Sort<TKey,TValue>(TKey[], TValue[], IComparer<TKey>) Überladung und eine Instanz von ReverseCompare werden verwendet, um die Sortierreihenfolge der gekoppelten Arrays umzukehren.

• Die Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32) Überladung wird verwendet, um die letzten drei Elemente beider Arrays zu sortieren.

• Die Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32, IComparer<TKey>) Überladung wird verwendet, um die letzten drei Elemente beider Arrays in umgekehrter Reihenfolge zu sortieren.

Hinweise

Jeder Schlüssel in der keysArray verfügt über ein entsprechendes Element im itemsArray. Wenn ein Schlüssel während der Sortierung neu positioniert wird, wird das entsprechende Element im itemsArray entsprechend neu positioniert. Daher wird die itemsArray nach der Anordnung der entsprechenden Schlüssel im keysArraysortiert.

Jeder Schlüssel in der keysArray muss die IComparable<T> generische Schnittstelle implementieren, um Vergleiche mit jedem anderen Schlüssel durchführen zu können.

Sie können sortieren, wenn mehr Elemente als Schlüssel vorhanden sind, aber die Elemente ohne entsprechende Schlüssel werden nicht sortiert. Sie können nicht sortieren, wenn mehr Schlüssel als Elemente vorhanden sind. Dadurch wird ein ArgumentExceptionausgelöst.

Wenn die Sortierung nicht erfolgreich abgeschlossen wurde, sind die Ergebnisse nicht definiert.

Diese Methode verwendet den Algorithmus für die introspektive Sortierung (introsorten) wie folgt:

• Wenn die Partitionsgröße kleiner oder gleich 16 Elemente ist, wird eine Einfügesortierung Algorithmus verwendet.

• Wenn die Anzahl der Partitionen 2 * Log^Nüberschreitet, wobei N der Bereich des Eingabearrays ist, wird ein Heapsort Algorithmus verwendet.

• Andernfalls wird ein Quicksort- Algorithmus verwendet.

Diese Implementierung führt eine instabile Sortierung durch; wenn zwei Elemente gleich sind, wird ihre Reihenfolge möglicherweise nicht beibehalten. Im Gegensatz dazu behält eine stabile Sortierung die Reihenfolge von Elementen bei, die gleich sind.

Diese Methode ist ein O(n Protokoll n) Vorgang, wobei n die Length von arrayist.

Beispiele

Das folgende Codebeispiel veranschaulicht die Sort<TKey,TValue>(TKey[], TValue[]), [], Sort<TKey,TValue>(TKey[], TValue[], IComparer<TKey>), Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32)und Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32, IComparer<TKey>) generische Methodenüberladungen zum Sortieren von Arrays, die Schlüssel und Werte darstellen.

Im Codebeispiel wird ein alternativer Vergleich für Zeichenfolgen mit dem Namen ReverseComparedefiniert, der die generische Schnittstelle IComparer<string> (IComparer(Of String) in Visual Basic, IComparer<String^> in Visual C++) implementiert. Der Comparer ruft die CompareTo(String)-Methode auf, wobei die Reihenfolge der Vergleiche umgekehrt wird, sodass die Zeichenfolgen anstelle von "niedrig" von "hoch" nach "hoch" sortieren.

Das Codebeispiel erstellt und zeigt ein Array von Dinosauriernamen (die Schlüssel) und ein Array von ganzen Zahlen an, die die maximale Länge jedes Dinosauriers in Metern (die Werte) darstellen. Die Arrays werden dann mehrmals sortiert und angezeigt:

• Die Sort<TKey,TValue>(TKey[], TValue[]) Überladung wird verwendet, um beide Arrays in der Reihenfolge der Dinosauriernamen im ersten Array zu sortieren.

• Die Sort<TKey,TValue>(TKey[], TValue[], IComparer<TKey>) Überladung und eine Instanz von ReverseCompare werden verwendet, um die Sortierreihenfolge der gekoppelten Arrays umzukehren.

• Die Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32) Überladung wird verwendet, um die letzten drei Elemente beider Arrays zu sortieren.

• Die Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32, IComparer<TKey>) Überladung wird verwendet, um die letzten drei Elemente beider Arrays in umgekehrter Reihenfolge zu sortieren.

Hinweise

Jeder Schlüssel in der keysArray verfügt über ein entsprechendes Element im itemsArray. Wenn ein Schlüssel während der Sortierung neu positioniert wird, wird das entsprechende Element im itemsArray entsprechend neu positioniert. Daher wird die itemsArray nach der Anordnung der entsprechenden Schlüssel im keysArraysortiert.

Wenn comparernullist, muss jeder Schlüssel in der keysArray die IComparable<T> generische Schnittstelle implementieren, um Vergleiche mit jedem anderen Schlüssel durchführen zu können.

Sie können sortieren, wenn mehr Elemente als Schlüssel vorhanden sind, aber die Elemente ohne entsprechende Schlüssel werden nicht sortiert. Sie können nicht sortieren, wenn mehr Schlüssel als Elemente vorhanden sind. Dadurch wird ein ArgumentExceptionausgelöst.

Wenn die Sortierung nicht erfolgreich abgeschlossen wurde, sind die Ergebnisse nicht definiert.

Diese Methode verwendet den Algorithmus für die introspektive Sortierung (introsorten) wie folgt:

• Wenn die Partitionsgröße kleiner oder gleich 16 Elemente ist, verwendet sie eine Einfügesortierung Algorithmus.

• Wenn die Anzahl der Partitionen 2 * Log^Nüberschreitet, wobei N der Bereich des Eingabearrays ist, wird ein Heapsort Algorithmus verwendet.

• Andernfalls wird ein Quicksort- Algorithmus verwendet.

Diese Implementierung führt eine instabile Sortierung durch; wenn zwei Elemente gleich sind, wird ihre Reihenfolge möglicherweise nicht beibehalten. Im Gegensatz dazu behält eine stabile Sortierung die Reihenfolge von Elementen bei, die gleich sind.

Diese Methode ist ein O(n Protokoll n) Vorgang, wobei n die Length von arrayist.

Hinweise für Aufrufer

.NET Framework 4 und frühere Versionen verwendeten nur den Quicksort-Algorithmus. Quicksort identifiziert ungültige Vergleiche in einigen Situationen, in denen der Sortiervorgang eine IndexOutOfRangeException Ausnahme auslöst, und löst eine ArgumentException Ausnahme für den Aufrufer aus. Ab .NET Framework 4.5 ist es möglich, dass Sortiervorgänge, die zuvor ArgumentException ausgelöst haben, keine Ausnahme auslösen, da die Einfügesortierungs- und Heapsortalgorithmen keinen ungültigen Vergleich erkennen. Dies gilt größtenteils für Arrays mit weniger als oder gleich 16 Elementen.

Der Comparer ruft die CompareTo(String)-Methode auf, wobei die Reihenfolge der Vergleiche umgekehrt wird, sodass die Zeichenfolgen anstelle von "niedrig" von "hoch" nach "hoch" sortieren.

Das Codebeispiel erstellt und zeigt ein Array von Dinosauriernamen (die Schlüssel) und ein Array von ganzen Zahlen an, die die maximale Länge jedes Dinosauriers in Metern (die Werte) darstellen. Die Arrays werden dann mehrmals sortiert und angezeigt:

• Die Sort<TKey,TValue>(TKey[], TValue[]) Überladung wird verwendet, um beide Arrays in der Reihenfolge der Dinosauriernamen im ersten Array zu sortieren.

• Die Sort<TKey,TValue>(TKey[], TValue[], IComparer<TKey>) Überladung und eine Instanz von ReverseCompare werden verwendet, um die Sortierreihenfolge der gekoppelten Arrays umzukehren.

• Die Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32) Überladung wird verwendet, um die letzten drei Elemente beider Arrays zu sortieren.

• Die Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32, IComparer<TKey>) Überladung wird verwendet, um die letzten drei Elemente beider Arrays in umgekehrter Reihenfolge zu sortieren.

Hinweise

Jeder Schlüssel in der keysArray verfügt über ein entsprechendes Element im itemsArray. Wenn ein Schlüssel während der Sortierung neu positioniert wird, wird das entsprechende Element im itemsArray entsprechend neu positioniert. Daher wird die itemsArray nach der Anordnung der entsprechenden Schlüssel im keysArraysortiert.

Jeder Schlüssel innerhalb des angegebenen Elementbereichs in der keysArray muss die IComparable<T> generische Schnittstelle implementieren, um Vergleiche mit jedem anderen Schlüssel zu ermöglichen.

Sie können sortieren, wenn mehr Elemente als Schlüssel vorhanden sind, aber die Elemente ohne entsprechende Schlüssel werden nicht sortiert. Sie können nicht sortieren, wenn mehr Schlüssel als Elemente vorhanden sind. Dadurch wird ein ArgumentExceptionausgelöst.

Wenn die Sortierung nicht erfolgreich abgeschlossen wurde, sind die Ergebnisse nicht definiert.

Diese Methode verwendet den Algorithmus für die introspektive Sortierung (introsorten) wie folgt:

• Wenn die Partitionsgröße kleiner oder gleich 16 Elemente ist, verwendet sie eine Einfügesortierung Algorithmus.

• Wenn die Anzahl der Partitionen 2 * Log^Nüberschreitet, wobei N der Bereich des Eingabearrays ist, wird ein Heapsort Algorithmus verwendet.

• Andernfalls wird ein Quicksort- Algorithmus verwendet.

Diese Implementierung führt eine instabile Sortierung durch; wenn zwei Elemente gleich sind, wird ihre Reihenfolge möglicherweise nicht beibehalten. Im Gegensatz dazu behält eine stabile Sortierung die Reihenfolge von Elementen bei, die gleich sind.

Diese Methode ist ein O(n Protokoll n) Vorgang, wobei nlengthist.
