C# - Remoting Client Server Example

This code snippet shows how to create a simple remoting client server program. The code shows how to use remoting to invoke a remote object.

1. // Create two projects (Client, Server)
2. // and Add a reference to System.Runtime.Remoting in both.
3. // Add the ICalculate Interface in both projects.
4.  
5.  
6. // Client.cs
7. using System;
8. using System.Runtime.Remoting;
9. using System.Runtime.Remoting.Channels;
10. using System.Runtime.Remoting.Channels.Tcp;
11.  
12.     class Program
13.     {
14.         static void Main(string[] args)
15.         {
16.             TcpClientChannel channel = new TcpClientChannel();
17.             ChannelServices.RegisterChannel(channel, false);
18.             ICalculate Employee = (ICalculate)Activator.GetObject(typeof(ICalculate), "tcp://localhost:5555/Calculate");
19.             Console.WriteLine(Employee.Sum(5, 5));
20.             Console.ReadKey();
21.         }
22.     }
23.  
24.     public interface ICalculate
25.     {
26.         int Sum(int a, int b);
27.     }

44.  
45.             RemotingConfiguration.RegisterWellKnownServiceType(remObj);
46.             Console.WriteLine("Server is running...");
47.             Console.ReadKey();
