指定したデリゲートで識別される、別のアプリケーションドメイン内のコードを実行します。

public:
 virtual void DoCallBack(CrossAppDomainDelegate ^ callBackDelegate);

public void DoCallBack(CrossAppDomainDelegate callBackDelegate);

abstract member DoCallBack : CrossAppDomainDelegate -> unit
override this.DoCallBack : CrossAppDomainDelegate -> unit

Public Sub DoCallBack (callBackDelegate As CrossAppDomainDelegate)

パラメーター

callBackDelegate: CrossAppDomainDelegate

呼び出すメソッドを指定するデリゲート。

実装

DoCallBack(CrossAppDomainDelegate)

例外

ArgumentNullException

callBackDelegate が nullです。

例

次の例では、静的 DoCallBack メソッドの使用を示します。

public ref class PingPong

        // Output:
