The following example code shows a custom proxy that overrides RealProxy.Invoke in order to write the call message information to the console.
virtual IMessage^ Invoke( IMessage^ myIMessage ) override { Console::WriteLine( "MyProxy::Invoke Start" ); Console::WriteLine( "" ); ReturnMessage^ myReturnMessage = nullptr; if ( dynamic_cast<IMethodCallMessage^>(myIMessage) ) { Console::WriteLine( "Message is of type 'IMethodCallMessage*'." ); Console::WriteLine( "" ); IMethodCallMessage^ myIMethodCallMessage; myIMethodCallMessage = dynamic_cast<IMethodCallMessage^>(myIMessage); Console::WriteLine( "InArgCount is : {0}", myIMethodCallMessage->InArgCount ); IEnumerator^ myEnum = myIMethodCallMessage->InArgs->GetEnumerator(); while ( myEnum->MoveNext() ) { Object^ myObj = safe_cast<Object^>(myEnum->Current); Console::WriteLine( "InArgs is : {0}", myObj ); } for ( int i = 0; i < myIMethodCallMessage->InArgCount; i++ ) { Console::WriteLine( "GetArgName({0}) is : {1}", i, myIMethodCallMessage->GetArgName( i ) ); Console::WriteLine( "GetInArg({0}) is : {0}", i, myIMethodCallMessage->GetInArg( i ) ); } Console::WriteLine( "" ); } else if ( dynamic_cast<IMethodReturnMessage^>(myIMessage) ) Console::WriteLine( "Message is of type 'IMethodReturnMessage*'." ); // Build Return Message myReturnMessage = gcnew ReturnMessage( 5,nullptr,0,nullptr,dynamic_cast<IMethodCallMessage^>(myIMessage) ); Console::WriteLine( "MyProxy::Invoke - Finish" ); return myReturnMessage; } }; // The class used to obtain Metadata. public ref class MyMarshalByRefClass: public MarshalByRefObject { public: int MyMethod( String^ str, double dbl, int i ) { Console::WriteLine( "MyMarshalByRefClass::MyMethod {0} {1} {2}", str, dbl, i ); return 0; } };
