8年前，令我窒息的Java socket体验学习

本来已经放弃编程了，那时我发誓再也不去IT培训班了，如果找不到工作，我就去工地上打工。可心有不甘，老是惦记着，我不想天天面对生产线，做一个丧失思考能力的操作工，可后来呀，还是走上了程序员之路。。。这么多年了，接触到C#的socket编程，可我还能感受到当时想去洋谷科技而又不能的那种无奈，迷茫。

我不会Java，仅用C#来说明，用socket实现聊天功能，代码是网上抄的，但可以说明当年我感觉高深的socket编程

Server:

 using System;
 using System.Net;
 using System.Net.Sockets;
 using System.IO;

 namespace TCPServer
 {
     class Program
     {
         static void Main(string[] args)
         {
             TcpClient client=null;
             try
             {
                 IPAddress myIp=IPAddress.Parse("127.0.0.1");
                 TcpListener myServer = new TcpListener(myIp, );

                 myServer.Start();
                 Console.WriteLine("Wait for client's connection....");

                 client = myServer.AcceptTcpClient();
                 Console.WriteLine("Client is already connected...");

                 NetworkStream stream = client.GetStream();
                 StreamReader sr = new StreamReader(stream);
                 StreamWriter sw = new StreamWriter(stream);

                 while(true)
                 {
                     Console.WriteLine("\nClient:\n" + sr.ReadLine()+"\n");
                     Console.WriteLine("Server:");
                     string msg= Console.ReadLine();
                     sw.WriteLine(msg);
                     sw.Flush();
                 }
             }
             catch
             {
                 if(client!=null)
                 {
                     client.Dispose();
                 }
             }
         }
     }
 }

Client：

 using System;
 using System.IO;
 using System.Net;
 using System.Net.Sockets;

 namespace TCPClient
 {
     class Program
     {
         static void Main(string[] args)
         {
             TcpClient client=null;
             try
             {
                 IPAddress myIp = IPAddress.Parse("127.0.0.1");
                 client = new TcpClient();
                 client.Connect(myIp, );
                 Console.WriteLine("server connected...please enter contact content...");  

                 NetworkStream stream = client.GetStream();
                 StreamReader sr = new StreamReader(stream);
                 StreamWriter sw = new StreamWriter(stream);  

                 while (true)
                 {
                     Console.WriteLine("Client:");
                     string msg = Console.ReadLine();
                     sw.WriteLine(msg);
                     sw.Flush();
                     Console.WriteLine("\nServer:\n" + sr.ReadLine()+"\n");
                 }
             }
             catch
             {
                 if(client!=null)
                 {
                     client.Dispose();
                 }
             }
         }
     }
 }

先运行Server端

看到Wait for client's connection... 后，运行client端

然后，client端发送信息"Hi Server, I am from client."到server端，server端收到client发来的消息

然后，server端发送信息"Hi Client, I am from Server."到client端，client端收到server发来的消息

按Ctrl+c先后中断客户端和服务端。
