Parameter

Gibt zurück

Eine 32-Bit-Ganzzahl mit Vorzeichen, die die lexikalische Beziehung der beiden verglichenen Elemente angibt.

Beispiele

Im folgenden Beispiel werden Teile von zwei Zeichenfolgen mit den verschiedenen CompareInfo Objekten verglichen:

• CompareInfo Objekt, das der spanischen Kultur (Spanien) mit internationaler Sortierung zugeordnet ist

• CompareInfo Objekt, das der spanischen Kultur (Spanien) mit traditioneller Sortierung zugeordnet ist

• CompareInfo -Objekt, das dem InvariantCulture

// The following code example compares two strings using the different CompareInfo instances:
//    a CompareInfo instance associated with the S"Spanish - Spain" culture with international sort,

Hinweise

Standardmäßig wird der Vergleich mithilfe CompareOptions.Nonevon ausgeführt. Wenn eine Sicherheitsentscheidung von einem Zeichenfolgenvergleich oder einer Änderung der Groß-/Kleinschreibung abhängt, sollten Sie die InvariantCulture -Eigenschaft verwenden, um sicherzustellen, dass das Verhalten unabhängig von den Kultureinstellungen des Betriebssystems konsistent ist.

Hinweise für Aufrufer

Zeichensätze enthalten ignorierbare Zeichen, d. h. Zeichen, die bei der Durchführung eines linguistischen oder kulturabhängigen Vergleichs nicht berücksichtigt werden. Die Compare(String, String) Methode berücksichtigt solche Zeichen nicht, wenn sie einen kulturabhängigen Vergleich durchführt. Für instance gibt ein kultursensitiver Vergleich von "Animal" mit "ani-mal" (unter Verwendung eines weichen Bindestrichs oder U+00AD) an, dass die beiden Zeichenfolgen gleichwertig sind, wie im folgenden Beispiel gezeigt.

Imports System.Globalization

Module Example
   Public Sub Main()
      Dim ci As CompareInfo = CultureInfo.CurrentCulture.CompareInfo
      Dim s1 As String = "ani" + ChrW(&h00AD) + "mal"
      Dim s2 As String = "animal"
      
      Console.WriteLine("Comparison of '{0}' and '{1}': {2}", 
                        s1, s2, ci.Compare(s1, s2))
  End Sub
End Module
' The example displays the following output:
'       Comparison of 'ani-mal' and 'animal': 0

Um nichtnorierbare Zeichen in einem Zeichenfolgenvergleich zu erkennen, rufen Sie die Compare(String, String, CompareOptions) -Methode auf, und geben Sie den Wert entweder Ordinal oder OrdinalIgnoreCase für den options -Parameter an.

Hinweise

Wenn eine Sicherheitsentscheidung von einem Zeichenfolgenvergleich oder einer Änderung der Groß-/Kleinschreibung abhängt, sollten Sie die InvariantCulture -Eigenschaft verwenden, um sicherzustellen, dass das Verhalten unabhängig von den Kultureinstellungen des Betriebssystems konsistent ist.

Hinweise für Aufrufer

Zeichensätze enthalten ignorierbare Zeichen, d. h. Zeichen, die bei der Durchführung eines linguistischen oder kulturabhängigen Vergleichs nicht berücksichtigt werden. Die Compare(String, String, CompareOptions) Methode berücksichtigt solche Zeichen nicht, wenn sie einen kulturabhängigen Vergleich durchführt. Um nichtnorierbare Zeichen in Ihrem Vergleich zu erkennen, geben Sie den Wert oder OrdinalOrdinalIgnoreCase für den options Parameter an.

Hinweise

Wenn eine Sicherheitsentscheidung von einem Zeichenfolgenvergleich oder einer Änderung der Groß-/Kleinschreibung abhängt, sollten Sie die InvariantCulture -Eigenschaft verwenden, um sicherzustellen, dass das Verhalten unabhängig von den Kultureinstellungen des Betriebssystems konsistent ist.

Hinweise für Aufrufer

Zeichensätze enthalten ignorierbare Zeichen. Die Compare(String, Int32, Int32, String, Int32, Int32) Methode berücksichtigt diese Zeichen nicht, wenn sie einen linguistischen oder kulturabhängigen Vergleich durchführt. Um ignorierbare Zeichen im Vergleich zu erkennen, rufen Sie die Compare(String, Int32, Int32, String, Int32, Int32, CompareOptions) -Methode auf, und geben Sie den Wert oder OrdinalOrdinalIgnoreCase für den options -Parameter an.
