Problem

You need to send data between two computers on a network using a TCP/IP connection.

Solution

One computer (the server) must begin listening using the System.Net.Sockets.TcpListener class. Another computer (the client) connects to it using the System.Net.Sockets.TcpClient class. Once a connection is established, both computers can communicate using the System.Net.Sockets.NetworkStream class.
