Property Value

Type: System::Int32

The number of arguments in the method call marked as ref or out parameters.

Exception Condition
SecurityException

The immediate caller makes the call through a reference to the interface and does not have infrastructure permission.

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

virtual IMessage^ Invoke( IMessage^ myMessage ) override
{
   IMethodCallMessage^ myCallMessage = (IMethodCallMessage^)( myMessage );

   IMethodReturnMessage^ myIMethodReturnMessage =
      RemotingServices::ExecuteMessage( myMarshalByRefObject, myCallMessage );

   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 );
   // Gets name and values of 'ref' and 'out' parameters.
   for ( int i = 0; i < myArgOutCount; i++ )
   {
      Console::WriteLine( "Name of argument {0} is '{1}'.",
         i, myIMethodReturnMessage->GetOutArgName( i ) );
      Console::WriteLine( "Value of argument {0} is '{1}'.",
         i, myIMethodReturnMessage->GetOutArg( i ) );
   }
   Console::WriteLine();
   array<Object^>^myObjectArray = myIMethodReturnMessage->OutArgs;
   for ( int i = 0; i < myObjectArray->Length; i++ )
      Console::WriteLine( "Value of argument {0} is '{1}' in OutArgs",
         i, myObjectArray[ i ] );
   return myIMethodReturnMessage;
}
