Assembly:

System.Reflection.Emit.dll

Quelle:

PropertyBuilder.cs

Legt die Methode zum Festlegen des Eigenschaftswerts fest.

public:
 void SetSetMethod(System::Reflection::Emit::MethodBuilder ^ mdBuilder);

public void SetSetMethod (System.Reflection.Emit.MethodBuilder mdBuilder);

member this.SetSetMethod : System.Reflection.Emit.MethodBuilder -> unit

Public Sub SetSetMethod (mdBuilder As MethodBuilder)

Parameter

Ausnahmen

ArgumentNullException

mdBuilder ist null.

InvalidOperationException

CreateType() wurde für den einschließenden Typ aufgerufen.

Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie eine dynamische Methode an eine set Eigenschaft angefügt wird, die mit PropertyBuilder erstellt wurde.SetSetMethod
