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, 6688);

                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, 6688);  
                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。
