这个是服务器端代码有问题还是客户端代码有问题??

以下是服务器端代码:

static void Main(string[] args)
        {
            IPAddress IP = IPAddress.Parse("127.0.0.1");
            int port = 10001;

            TcpListener server = new TcpListener(IP, port);
            server.Start();

            Console.WriteLine("等待客户机连接");

            Socket socket = server.AcceptSocket();
            Console.WriteLine("服务器接受连接");

            while (true)
            {
                try
                {
                    Console.WriteLine("联机成功！");
                    byte[] buff = new byte[1024];
                    int length = socket.Receive(buff);
                    string data = Encoding.ASCII.GetString(buff, 0, length);
                }
                catch (Exception e)
                {
                    Console.WriteLine("客户机离开");
                    socket.Close();
                }
            }
            Console.ReadLine();
        }
