IMethodMessage.MethodName プロパティ

呼び出されたメソッドの名前を取得します。

名前空間: System.Runtime.Remoting.Messaging
アセンブリ: mscorlib (mscorlib.dll 内)
構文

Visual Basic (宣言)

ReadOnly Property MethodName As
 String

Visual Basic (使用法)

Dim instance As IMethodMessage
Dim value As String

value = instance.MethodName

string MethodName { get; }

C++

property String^ MethodName {
    String^ get ();
}

/** @property */
String get_MethodName ()

JScript

function get MethodName () : String

プロパティ値
呼び出されたメソッドの名前。

例外

例外の種類	条件
SecurityException	直前の呼び出し元は、インターフェイスへの参照を通じて呼び出しを実行します。この呼び出し元には、インフラストラクチャアクセス許可がありません。

使用例

RealProxy.Invoke をオーバーライドして、メソッドの名前をコンソールに書き込むカスタムプロキシについては、次のコード例を参照してください。
