private void ConnectToServer()
{
    using (TcpClient tc = new TcpClient("127.0.0.1", 12))
    {
        NetworkStream ns = tc.GetStream();
        StreamWriter sw = new StreamWriter(ns);
        StreamReader sr = new StreamReader(ns);

        sw.WriteLine("test message");
        sw.Flush();
        System.Console.WriteLine(sr.ReadLine());
    }
}
