Beispiele

Im folgenden Beispiel wird die ToBase64String(Byte[])-Methode verwendet, um ein Bytearray in eine UUencoded -Zeichenfolge (Base-64) zu konvertieren, und ruft dann die FromBase64String(String)-Methode auf, um das ursprüngliche Bytearray wiederherzustellen.

using System;

public class Example
{
   public static void Main()
   {
       // Define a byte array.
       byte[] bytes = { 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 };
       Console.WriteLine("The byte array: ");
       Console.WriteLine("   {0}\n", BitConverter.ToString(bytes));

       // Convert the array to a base 64 string.
       string s = Convert.ToBase64String(bytes);
       Console.WriteLine("The base 64 string:\n   {0}\n", s);

       // Restore the byte array.
       byte[] newBytes = Convert.FromBase64String(s);
       Console.WriteLine("The restored byte array: ");
       Console.WriteLine("   {0}\n", BitConverter.ToString(newBytes));
   }
}

' The example displays the following output:

Im Folgenden sehen Sie ein komplexeres Beispiel, das ein 20-Elementarray mit 32-Bit-Ganzzahlen erstellt. Anschließend wird die BitConverter.GetBytes(Int32)-Methode verwendet, um jedes Element in ein Bytearray zu konvertieren, das in der entsprechenden Position in einem Puffer gespeichert wird, indem die Array.Copy(Array, Int32, Array, Int32, Int32)-Methode aufgerufen wird. Dieser Puffer wird dann an die ToBase64String(Byte[])-Methode übergeben, um eine UUencoded -Zeichenfolge (Base-64) zu erstellen. Anschließend ruft sie die FromBase64String(String)-Methode auf, um die UUencoded-Zeichenfolge zu decodieren, und ruft die BitConverter.ToInt32-Methode auf, um jeden Satz von vier Byte (die Größe einer 32-Bit-Ganzzahl) in eine ganze Zahl zu konvertieren. Die Ausgabe aus dem Beispiel zeigt, dass das ursprüngliche Array erfolgreich wiederhergestellt wurde.

Hinweise

Die Elemente von inArray werden als numerischer Wert verwendet und in eine Zeichenfolgendarstellung konvertiert, die mit Base64-Ziffern codiert ist.

Die Base64-Ziffern in aufsteigender Reihenfolge von null sind die Großbuchstaben "A" bis "Z", die Kleinbuchstaben "a" in "z", die Ziffern "0" in "9" und die Symbole "+" und "/". Das wertlose Zeichen "=" wird für nachfolgende Abstände verwendet.

Ordinarily, the ToBase64String method is not used to round-trip a UUEncoded (base-64 encoded) string. Wenn Sie also eine Zeichenfolge durch Aufrufen der FromBase64String-Methode decodieren, codieren Sie das zurückgegebene Bytearray durch Aufrufen der ToBase64String-Methode, ist die resultierende Zeichenfolge nicht unbedingt identisch mit der ursprünglichen Zeichenfolge. Die Zeichenfolge wird nur gerundet, wenn die ursprüngliche Zeichenfolge eine gültige base64-codierte Zeichenfolge ist.

Hinweise

Die Elemente des inArray-Parameters werden als numerischer Wert verwendet und in eine Zeichenfolgendarstellung in Basis 64 konvertiert.

Die Base64-Ziffern in aufsteigender Reihenfolge von null sind die Großbuchstaben "A" bis "Z", die Kleinbuchstaben "a" in "z", die Ziffern "0" in "9" und die Symbole "+" und "/". Das wertlose Zeichen "=" wird für nachfolgende Abstände verwendet.

Wenn der parameter options auf InsertLineBreaks festgelegt ist und die Ausgabe der Konvertierung länger als 76 Zeichen ist, wird ein Zeilenumbruch alle 76 Zeichen eingefügt. Ein Zeilenumbruch wird als Wagenrücklaufzeichen (U+000D) gefolgt von einem Zeilenvorschubzeichen (U+000A) definiert. Da Zeilenumbrüche als Leerzeichen in einer Base64-Codierung gelten, werden sie beim Konvertieren einer base64-codierten Zeichenfolge zurück in ein Bytearray ignoriert. Die Zeilenumbrüche sind einfach praktisch, wenn die codierte Zeichenfolge auf einem Steuerelement oder einem Gerät wie einem Konsolenfenster angezeigt wird.

Beispiele

Im folgenden Beispiel wird die ToBase64String-Methode veranschaulicht. Die Eingabe wird in Gruppen von drei Bytes (jeweils 24 Bit) unterteilt. Folglich besteht jede Gruppe aus vier 6-Bit-Zahlen, bei denen jede Zahl zwischen Dezimalzahl 0 und 63 liegt. In diesem Beispiel gibt es 85 3-Byte-Gruppen mit einem byte verbleibenden Byte. Die erste Gruppe besteht aus den Hexadezimalwerten 00, 01 und 02, die vier 6-Bit-Werte mit dezimal 0, 0, 4 und 2 ergeben. Diese vier Werte entsprechen den Basis-64 Ziffern "A", "A", "E" und "C" am Anfang der Ausgabe.

Wenn keine integrale Anzahl von 3-Byte-Gruppen vorhanden ist, werden die verbleibenden Bytes effektiv mit Nullen aufgefüllt, um eine vollständige Gruppe zu bilden. In diesem Beispiel ist der Wert des letzten Bytes hexadezimal FF. Die ersten 6 Bits sind gleich dezimal 63, was der Basis-64-Ziffer "/" am Ende der Ausgabe entspricht, und die nächsten 2 Bits werden mit Nullen aufgefüllt, um eine Dezimalzahl von 48 zu erzielen, die der Basis-64-Ziffer "w" entspricht. Die letzten beiden 6-Bit-Werte sind Abstand und entsprechen dem wertlosen Abstandszeichen "=".

Hinweise

Die Elemente des inArray-Parameters werden als numerischer Wert verwendet und in eine Zeichenfolgendarstellung in Basis 64 konvertiert.

Die Base64-Ziffern in aufsteigender Reihenfolge von null sind die Großbuchstaben "A" bis "Z", die Kleinbuchstaben "a" in "z", die Ziffern "0" in "9" und die Symbole "+" und "/". Das wertlose Zeichen "=" wird für nachfolgende Abstände verwendet.

Die Parameter offset und length sind 32-Bit-Signierte Nummern. Der parameter offset ist nullbasiert.

Wenn der parameter options auf InsertLineBreaks festgelegt ist und die Ausgabe der Konvertierung länger als 76 Zeichen ist, wird ein Zeilenumbruch alle 76 Zeichen eingefügt. Ein Zeilenumbruch wird als Wagenrücklaufzeichen (U+000D) gefolgt von einem Zeilenvorschubzeichen (U+000A) definiert. Weitere Informationen finden Sie unter RFC 2045, "Multipurpose Internet Mail Extensions", unter https://www.rfc-editor.org/.
