AssemblyName.SetPublicKey(Byte[]) Methode

public:
 void SetPublicKey(cli::array <System::Byte> ^ publicKey);

public void SetPublicKey (byte[] publicKey);

public void SetPublicKey (byte[]? publicKey);

member this.SetPublicKey : byte[] -> unit

Public Sub SetPublicKey (publicKey As Byte())

Parameter

Beispiele

Im folgenden Beispiel wird eine dynamische Assembly ausgegeben und im aktuellen Verzeichnis gespeichert. Wenn die Assembly erstellt wird, wird die SetPublicKey -Methode verwendet, um der Assembly einen öffentlichen Schlüssel zu geben. Die GetPublicKey -Methode wird dann verwendet, um den öffentlichen Schlüssel abzurufen, der in der Konsole angezeigt wird.

Hinweise

Sie müssen auch die SetPublicKeyToken -Methode verwenden, um ein Öffentliches Schlüsseltoken bereitzustellen. Andernfalls wird ein SecurityException ausgelöst, wenn die GetPublicKey -Methode aufgerufen wird.
