IMethodMessage Interface

Defines the method message interface.

Namespace: System.Runtime.Remoting.Messaging

A method message is used to send information to and from remote methods. For example, messages used for remote method calls implement the IMethodMessage interface.

The following example code shows a custom proxy that overrides RealProxy.Invoke in order to write the message information to the console and return immediately without making a remote call.

[PermissionSet(SecurityAction.Demand, Name="FullTrust")]
public class MyProxyClass : RealProxy
   private Object  myObjectInstance  = null;
   private Type    myType      = null;

   public MyProxyClass(Type argType) : base(argType)
      myType = argType;
      myObjectInstance = Activator.CreateInstance(argType);

   // Overriding the Invoke method of RealProxy.
   public override IMessage Invoke(IMessage message)
      IMethodMessage myMethodMessage = (IMethodMessage)message;

      Console.WriteLine("**** Begin Invoke ****");
      Console.WriteLine("\tType is : " + myType);
      Console.WriteLine("\tMethod name : " +  myMethodMessage.MethodName);

      for (int i=0; i < myMethodMessage.ArgCount; i++)
         Console.WriteLine("\tArgName is : " + myMethodMessage.GetArgName(i));
         Console.WriteLine("\tArgValue is: " + myMethodMessage.GetArg(i));

          Console.WriteLine("\t The method have variable arguments!!");
          Console.WriteLine("\t The method does not have variable arguments!!");

      // Dispatch the method call to the real object.
      Object returnValue = myType.InvokeMember( myMethodMessage.MethodName, BindingFlags.InvokeMethod, null,
                                           myObjectInstance, myMethodMessage.Args );
      Console.WriteLine("**** End Invoke ****");

      // Build the return message to pass back to the transparent proxy.
      ReturnMessage myReturnMessage = new ReturnMessage( returnValue, null, 0, null,
          (IMethodCallMessage)message );
      return myReturnMessage;
