TcpClient和Tcplistener

前天去面试，让写这东西

之前的项目也做过这东西，好长时间没看，就给忘了，惭愧！今天重新拾起来，做了个简单的demo

Client端

    static void Main(string[] args)
        {
            TcpClient client = new System.Net.Sockets.TcpClient();

            client.Connect(IPAddress.Parse("127.0.0.1"), );  //连接到服务器

            NetworkStream ns= client.GetStream();                //获取socket网络流对象

            byte[] buffer=  System.Text.ASCIIEncoding.Default.GetBytes("this message from client"); //字符串编码

            ns.Write(buffer, , buffer.Length);                 //发送二进制数组

            ns.Close();
            client.Close();
        }

Server端

 static void Main(string[] args)
        {
            System.Net.Sockets.TcpListener server = new System.Net.Sockets.TcpListener(); //创建服务器的socket
            server.Start();                                                   //开始监听
            System.Net.Sockets.TcpClient client = server.AcceptTcpClient();     //获取到客户端的TcpClient对象
            System.Net.Sockets.NetworkStream ns = client.GetStream();           //获取到网络流NetworkStream对象
            string str = new StreamReader(ns).ReadToEnd();                      //读取到NetworkStream中的字符串
        }
