C# TCP/IP (线程池监控)

服务端

客户端

            TcpClient tcpClient = new TcpClient();//创建一个TcpClient对象，自动分配主机IP地址和端口号
            tcpClient.Connect("127.0.0.1", 10010);//连接服务器，其IP和端口号为127.0.0.1和888
            if (tcpClient != null)
            {
                Console.WriteLine("连接服务器成功");
                NetworkStream networkStream = tcpClient.GetStream();//获取网络数据流
                BinaryReader reader = new BinaryReader(networkStream);//定义数据读取对象
                BinaryWriter writer = new BinaryWriter(networkStream);//定义数据写入对象
                string localip = "127.0.0.1";//存储本机IP，默认值为127.0.0.1
                IPAddress[] ips = Dns.GetHostAddresses(Dns.GetHostName());//获取所有Ip地址
                foreach (var item in ips)
                {
                    //如果不是ipv6
                    if (!item.IsIPv6LinkLocal)
                    {
                        if (!item.IsIPv6Teredo)
                        {
                            localip = item.ToString();
                        }
                    }
                }


                writer.Write(localip + " 你好服务器，我是客服端" + ass);//向服务器发送消息

                while (true)
                {
                    try
                    {
                        string strReader = reader.ReadString();//接收服务器发送的数据
                        if (strReader != null)
                        {
                            Console.WriteLine("来自服务器的消息：" + strReader + "   " + ass);//输出接收服务器的消息
                        }

                    }
                    catch (Exception e)
                    {
                        tcpClient.Close();
                        Console.WriteLine("错误！！" + e.Message);
                        break;//出错退出循环
                    }
                }

            }
            else
            {
                Console.WriteLine("连接服务器错误");
            }
        

当某些情况需要客户端对接受数据的等待时间设置超时可以设置NetworkStream的ReadTimeout属性(单位为毫秒)
