Asynchronous call

// This is an example of an asynchronous call. SimpleMath has an asynchronous method called BeginAdd. Who can change the SimpleNath class to a form that contains beginxxx and endxxx methods, like asynchronous calls like beginxxx and endxxx in a socket.

using System.Runtime.Remoting.Messaging;
using System.Threading;

namespace DemoDelegate
{
public delegate int AddDelegate (int n1, int n2);
class Class1
{
static void Main (string [] args)
{
SimpleMath math = new SimpleMath ();
IAsyncResult asyncResult = math.BeginAdd (2,5, new AsyncCallback (AddCallback));
Console.WriteLine ("Press Enter to terminate the program ...");
Console.Read ();
}

// Addition callback function
private static void AddCallback (IAsyncResult ar)
{
AsyncResult async = (AsyncResult) ar;
AddDelegate d = (AddDelegate) async.AsyncDelegate;
int result = d.EndInvoke (ar);
Console.WriteLine ("2 + 5 =" + result);

// addition

Thread.Sleep (2000);

In the CS program, when remoting peer-to-peer communication is used, if I do not use the event repeater mode, I directly transfer the set delegate to the server, and then the server implements the remote callback method in the callback client method. Is this method the same as two-machine communication? ?
