IMethodReturnMessage Interface
.NET Framework 2.0
Defines the method call return message interface.
Namespace: System.Runtime.Remoting.Messaging
Assembly: mscorlib (in mscorlib.dll)

'Declaration <ComVisibleAttribute(True)> _ Public Interface IMethodReturnMessage Inherits IMethodMessage, IMessage 'Usage Dim instance As IMethodReturnMessage
/** @attribute ComVisibleAttribute(true) */ public interface IMethodReturnMessage extends IMethodMessage, IMessage

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