Parameter

Gibt zurück

Ein MethodBuilder-Objekt, das die neu hinzugefügte Methode darstellt.

Ausnahmen

Hinweise

Verwenden Sie diese Überladung, wenn Sie benutzerdefinierte Modifizierer angeben müssen. Wenn Sie benutzerdefinierte Modifizierer angeben müssen, nachdem die Methode erstellt wurde, wie z. B. bei einer generischen Methode, deren Parametertypen durch ihre generischen Typparameter angegeben werden, können Sie die DefineMethod(String, MethodAttributes) - oder DefineMethod(String, MethodAttributes, CallingConventions) -Methodenüberladungen verwenden, um die -Methode zu definieren und dann mit der MethodBuilder.SetSignature -Methode den Parameter zu definieren und Typen mit benutzerdefinierten Modifizierern zurückzugeben.

Hinweise

Verwenden Sie diese Methodenüberladung, wenn Sie die Methodensignatur zum Zeitpunkt der Definition der Methode nicht kennen. Beispielsweise können die Parametertypen und der Rückgabetyp einer generischen Methode durch die generischen Typparameter der Methode angegeben werden, die definiert werden müssen, nachdem die Methode dem Typ hinzugefügt wurde. Die Parameter und der Rückgabetyp der Methode können später mithilfe der MethodBuilder.SetSignature -Methode festgelegt werden.

Beispiele

Im folgenden Codebeispiel wird eine generische Methode mit dem Namen DemoMethod definiert, deren Parametertyp und Rückgabetyp durch ihre generischen Typparameter angegeben werden. Die Methode wird ohne Signatur mithilfe der Standardaufrufkonvention definiert. Die MethodBuilder.DefineGenericParameters -Methode wird verwendet, um eine generische Methode zu erstellen DemoMethod , und die neu definierten Typparameter werden dann für die Signatur und den Rückgabetyp verwendet.

Dieses Codebeispiel ist Teil eines größeren Beispiels für die DefineGenericParameters -Methode.
