class Program
    int port = 80;

    static void Main(string[] args)
        Program program = new Program();
    public void ClientMain()
        IPEndPoint ip = new IPEndPoint(IPAddress.Parse(""), port);
        Socket client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        new TcpListener(client);

public class TcpListener
    Thread inThread, outThread;
    NetworkStream stream;
    StreamReader reader;
    StreamWriter writer;
    public TcpListener(Socket client)

        stream = new NetworkStream(client);
        reader = new StreamReader(stream);
        writer = new StreamWriter(stream);
        inThread = new Thread(new ThreadStart(inLoop));
        outThread = new Thread(new ThreadStart(outLoop));
    public void inLoop()
        while (true)
            String s = reader.ReadLine();
            Console.WriteLine("server:" + s);           

    public void outLoop()
        while (true)

There is already a tutorial on the site here: [Introduction-to-TCP-client-server-in-C]

If you read the example and make it as the example you should be able to do this in your own code.

goodluck :)
