Examples

The following example code shows a custom proxy that overrides RealProxy.Invoke in order to write the return message information to the console.

   Console::WriteLine( "Method name : {0}", myIMethodReturnMessage->MethodName );
   Console::WriteLine( "The return value is : {0}", myIMethodReturnMessage->ReturnValue );

   // Get number of 'ref' and 'out' parameters.
   int myArgOutCount = myIMethodReturnMessage->OutArgCount;
   Console::WriteLine( "The number of 'ref', 'out' parameters are : {0}",
      myIMethodReturnMessage->OutArgCount );
