TcpListener 、TcpClient_01

客户端：

            System.Net.Sockets.TcpClient tcpClient = new System.Net.Sockets.TcpClient();
            tcpClient.Connect(hostname: "127.0.0.1", port: 12345);
            var stream = tcpClient.GetStream();
            while (true)
            {
                byte[] message = Encoding.UTF8.GetBytes($"发送:{DateTime.Now.ToString()}");
                //写入数据流
                stream.Write(message, 0, message.Length);
                Console.WriteLine($"{Encoding.UTF8.GetString(message)}");
                Thread.Sleep(1000);

服务端：

        {

            TcpListener listener = new TcpListener(IPAddress.Loopback, 12345);
            listener.Start();
            byte[] buffer = new byte[20];
            var clientStream = listener.AcceptTcpClient().GetStream();
            Task.Factory.StartNew(() =>
            {
                while (true)
                {
                    //   读取数据流
                    clientStream.Read(buffer, 0, buffer.Length);
                    var message = Encoding.UTF8.GetString(buffer);
                    Console.WriteLine($"{message}");

                    //  Console.WriteLine($"{ex.Message}{ex.StackTrace}");
                }

            });
            Console.ReadLine();
        }
