IMethodReturnMessage.OutArgs Property

Returns the specified argument marked as a ref or an out parameter.

Namespace:  System.Runtime.Remoting.Messaging
Assembly:  mscorlib (in mscorlib.dll)

Object[] OutArgs { get; }

Property Value

Type: System.Object[]
The specified argument marked as a ref or an out parameter.


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

Although the OutArgs property is redundant since the same functionality can be achieved through the OutArgCount field and GetOutArg method, there might be performance optimization available if the implementer understands when all the arguments will be retrieved.

public override IMessage Invoke(IMessage myMessage)
   IMethodCallMessage myCallMessage = (IMethodCallMessage)myMessage;

   IMethodReturnMessage myIMethodReturnMessage =
      RemotingServices.ExecuteMessage(myMarshalByRefObject, myCallMessage);

   Console.WriteLine("Method name : " + myIMethodReturnMessage.MethodName);
   Console.WriteLine("The return value is : " + myIMethodReturnMessage.ReturnValue);

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

   for(int i = 0; i < myObjectArray.Length; i++)
      Console.WriteLine("Value of argument {0} is '{1}' in OutArgs",
         i, myObjectArray[i]);
   return myIMethodReturnMessage;
