C# 客户端服务端的编写

客户端的代码 
class client
    {

        public void mehod()
        {
            TcpClient tcp = new TcpClient();
            tcp.Connect(IPAddress.Parse("192.168.0.168"), );

            NetworkStream stream = tcp.GetStream();

            string cmd = "demo TESTING";

            byte[] outbytes = System.Text.Encoding.ASCII.GetBytes(cmd.ToCharArray());

            stream.Write(outbytes, , outbytes.Length);

            byte[] buffer = new byte[];
            int len = stream.Read(buffer, , buffer.Length);
            string msg = System.Text.Encoding.ASCII.GetString(buffer, , len);

            Console.WriteLine("客户端执行。。。。。。");
            new server().method();
            tcp.Close();

            Console.ReadLine();
        }

    }
服务端的代码：

 class server
    {
        public void method()
        {
            IPAddress ipaddress = IPAddress.Parse("192.168.0.168");

            TcpListener listener = new TcpListener(ipaddress, 23850);

            listener.Start();
            Console.WriteLine("服务端执行");
            Console.ReadLine();

            Socket socket = listener.AcceptSocket();

            byte[] buffer = new byte[1024];
            socket.Receive(buffer);

            string message = "hello";
            byte[] outbytes = System.Text.Encoding.ASCII.GetBytes(message.ToCharArray());
            socket.Send(outbytes, message.Length, 0);

            socket.Close();
        }
    }
