AppDomain.DoCallBack メソッド

[アーティクル]
03/28/2008

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 Overridable Sub DoCallBack( _
   ByVal callBackDelegate As CrossAppDomainDelegate _) Implements _AppDomain.DoCallBack
[C#]
public virtual void DoCallBack(CrossAppDomainDelegatecallBackDelegate);
[C++]
public: virtual void DoCallBack(CrossAppDomainDelegate* callBackDelegate);
[JScript]
public function DoCallBack(
   callBackDelegate : CrossAppDomainDelegate);

パラメータ

callBackDelegate
呼び出すメソッドを指定するデリゲート。

実装

_AppDomain.DoCallBack

解説

callBackDelegate には、値渡しによるマーシャリングオブジェクト、 MarshalByRefObject 、または ContextBoundObject を指定できます。

使用例

[Visual Basic, C#, C++] 静的な DoCallBack メソッドの使用方法を次のサンプルで示します。

 
Public Module PingPong

   Private greetings As String = "PONG!"
   
   Sub Main()
      Dim currentDomain As AppDomain = AppDomain.CurrentDomain
      Dim otherDomain As AppDomain = AppDomain.CreateDomain("otherDomain")
      
      greetings = "PING!"

      MyCallBack()
      otherDomain.DoCallBack(AddressOf MyCallBack)

      ' Output:
      '   PING! from default domain
      '   PONG! from otherDomain
   End Sub 'Main
   
   Sub MyCallBack()
      Dim name As String = AppDomain.CurrentDomain.FriendlyName
      Console.WriteLine(greetings + " from " + name)
   End Sub 'MyCallBack

End Module 'PingPong

[C#] 
static string greetings = "PONG!";

public static void Main() {
   AppDomain currentDomain = AppDomain.CurrentDomain;
   AppDomain otherDomain = AppDomain.CreateDomain("otherDomain");

   greetings = "PING!";

   MyCallBack();
   otherDomain.DoCallBack(new CrossAppDomainDelegate(MyCallBack));

   // Output:
   //   PING! from default domain
   //   PONG! from otherDomain
}

static public void MyCallBack() {
   string name = AppDomain.CurrentDomain.FriendlyName;
   Console.WriteLine(greetings + " from " + name);
}

[C++] 
public __gc class PingPong {
   static String* greetings = S"PONG!";

public:
   static void MyCallBack() {
      String* name = AppDomain::CurrentDomain->FriendlyName;
      Console::WriteLine("{0} from {1}", greetings, name);
   }
   static void Ping() {
      AppDomain*  currentDomain = AppDomain::CurrentDomain;
      AppDomain*  otherDomain = AppDomain::CreateDomain(S"otherDomain");

      greetings = S"PING!";

      MyCallBack();
      otherDomain->DoCallBack(new CrossAppDomainDelegate(0, MyCallBack));

      // Output:
      //   PING! from default domain
      //   PONG! from otherDomain
   }
};

int main() {
   PingPong::Ping();
}
