System.Runtime.Remoting.Messaging.IMethodReturnMessage Interface

Summary

Defines the method call return message interface.

C# Syntax:

public interface IMethodReturnMessage : IMethodMessage, IMessage

A method call return message represents the response to a method call on an object at the end of the message sink. An IMethodReturnMessage is generated as a result of a method called on a remote object, and is used to return the results of the method call back to the caller.

C# Syntax:

object[] OutArgs {get;}

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