There are a number of chat-type applications on codeplex.com complete with source code.

The .NET Framework provides us with a higher level of abstraction upon sockets in the form of TcpListener and TcpClient. TcpListener is a high level interface for server and TCPClient is for client application.
It will use two namespaces System.Net and System.Net.Sockets which are required for Socket Programming. Basically, TCPListener class provides simple methods to listen and accepts incoming connection requests whereas, TcpClient class implements a socket for sending and receiving data using TCP.
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Net.Sockets;
using System.IO;
namespace TcpServer
    class ServerClass
        static void Main(string[] args)
            IPAddress IP = IPAddress.Parse(""); 

// Local address to listen.
            TcpListener Listener = new TcpListener(IP, 1986); 
// Listening from TCP clients.
            Listener.Start(); // Starts listening for incoming requests.
            Console.WriteLine("Server is up at port 1986");
            Console.WriteLine("Waiting for the connection...");
            ClientClass user = new ClientClass(Listener.AcceptTcpClient());
            string Message = Console.ReadLine();
    class ClientClass
        TcpClient Client;
        byte[] Data;
        bool Flag = true;
        NetworkStream netStream;
        // When a client comes in.
        public ClientClass(TcpClient newClient)
            Client = newClient;
            Console.WriteLine("Connected with " + Client.Client.RemoteEndPoint);
            // To notify the client about his connection.
            // For receiving the data.       
            Data = new byte[100];
            netStream = Client.GetStream();
            netStream.BeginRead(Data, 0, 100, ReceiveMessage, null);
        // Read from clients.
        public void ReceiveMessage(IAsyncResult ar)
            int bufferLength;
                bufferLength = Client.GetStream().EndRead(ar);
                // Receive the message from client side.
                string messageReceived = Encoding.ASCII.GetString(Data, 0,
                // Display it on server's console.
                Console.WriteLine(Client.Client.RemoteEndPoint.ToString() + "-> "

 + messageReceived);
                // Continue reading from client. 
                Client.GetStream().BeginRead(Data, 0, 100, ReceiveMessage, null);
            catch(Exception ex)
                Console.WriteLine(Client.Client.RemoteEndPoint.ToString() + " 
is disconnected.");
        // Send the message.
        public void SendMessage(string message)
                byte[] bytesToSend = System.Text.Encoding.ASCII.GetBytes(message);
            catch (Exception ex)
