Socket

网络上的两个程序通过一个双向的通信连接实现数据交换，这个连接的一端称为一个 Socket ，Socket 包含了网络通信必须的五种信息

Socket 例子{

协议： TCP

本地： IP ，端口

远程： IP ，端口

}

可以通过ipconfig，netstat -ano 查看 Ip 和端口

创建客户端连接服务端

客户端代码：

using System;
using System.Net.Sockets;namespace wangluo
{class Program{static void Main(string[] args){//创建一个Socket 需要using System.Net.Sockets;Socket tempClient = new Socket(AddressFamily.InterNetwork,SocketType.Stream, ProtocolType.Tcp);tempClient.Connect("127.0.0.1", 8888);}}
}

服务端代码：

using System;
using System.Net.Sockets;
using System.Net;namespace Server
{class Program{static void Main(string[] args){Socket tempServer = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);IPEndPoint tempEndPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8888);  //using System.Net;tempServer.Bind(tempEndPoint);  //绑定端口tempServer.Listen(0);  //监听，0表示挂起的队列无限长Console.WriteLine("服务端启动成功");Socket tempConnectClient = tempServer.Accept();Console.WriteLine("客户端连接成功:" + tempConnectClient);}}
}

先开启服务端再开启客户端

客户端服务端互发信息

客户端代码：

using System;
using System.Net.Sockets;
using System.Text;namespace wangluo
{class Program{static void Main(string[] args){//创建一个Socket 需要using System.Net.Sockets;Socket tempClient = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);tempClient.Connect("127.0.0.1", 8888);//客户端向服务端发信息string tempSendInfo = Console.ReadLine();//将字符串转换成 bufferbyte[] tempSendData = Encoding.UTF8.GetBytes(tempSendInfo);//发送信息tempClient.Send(tempSendData);//接收来自服务端的信息byte[] tempReadBuffer = new byte[1024];tempClient.Receive(tempReadBuffer);string tempReadString = Encoding.UTF8.GetString(tempReadBuffer);Console.WriteLine("接收到服务端信息：" + tempReadString);}}
}

服务端代码：

using System;
using System.Net.Sockets;
using System.Net;
using System.Text;namespace Server
{class Program{static void Main(string[] args){Socket tempServer = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);IPEndPoint tempEndPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8888);  //using System.Net;tempServer.Bind(tempEndPoint);  //绑定端口tempServer.Listen(0);  //监听，0表示挂起的队列无限长Console.WriteLine("服务端启动成功");Socket tempConnectClient = tempServer.Accept();Console.WriteLine("客户端连接成功:" + tempConnectClient);byte[] tempReadBuffer = new byte[1024];tempConnectClient.Receive(tempReadBuffer);//将 byte 转换成字符串string tempReadString = Encoding.UTF8.GetString(tempReadBuffer);Console.WriteLine("接收到客户端信息：" + tempReadString);//服务端向客户端发信息string tempSendInfo = Console.ReadLine();byte[] tempSendData = Encoding.UTF8.GetBytes(tempSendInfo);tempConnectClient.Send(tempSendData);}}
}

封装一下代码：

客户端：

using System;
using System.Net.Sockets;
using System.Text;namespace wangluo
{class Program{static void Main(string[] args){//创建一个Socket 需要using System.Net.Sockets;Socket tempClient = CreateSocket();tempClient.Connect("127.0.0.1", 8888);Send(tempClient);Receive(tempClient);}static Socket CreateSocket(){return new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);}static void Send(Socket tempClient){//客户端向服务端发信息string tempSendInfo = Console.ReadLine();//将字符串转换成 bufferbyte[] tempSendData = Encoding.UTF8.GetBytes(tempSendInfo);//发送信息tempClient.Send(tempSendData);}static void Receive(Socket tempClient){//接收来自服务端的信息byte[] tempReadBuffer = new byte[1024];tempClient.Receive(tempReadBuffer);string tempReadString = Encoding.UTF8.GetString(tempReadBuffer);Console.WriteLine("接收到服务端信息：" + tempReadString);}}
}

服务端：

using System;
using System.Net.Sockets;
using System.Net;
using System.Text;namespace Server
{class Program{static void Main(string[] args){Socket tempServer = CreateSocket();BindAndListen(tempServer);Socket tempConnectClient = Accept(tempServer);Receive(tempConnectClient);Send(tempConnectClient);}static Socket CreateSocket(){return new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);}static void BindAndListen(Socket pSocket){IPEndPoint tempEndPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8888);  //using System.Net;pSocket.Bind(tempEndPoint);  //绑定端口pSocket.Listen(0);  //监听，0表示挂起的队列无限长Console.WriteLine("服务端启动成功");}static Socket Accept(Socket pSocket){Socket tempConnectClient = pSocket.Accept();Console.WriteLine("客户端连接成功:" + tempConnectClient);return tempConnectClient;}static void Receive(Socket pSocket){byte[] tempReadBuffer = new byte[1024];pSocket.Receive(tempReadBuffer);//将 byte 转换成字符串string tempReadString = Encoding.UTF8.GetString(tempReadBuffer);Console.WriteLine("接收到客户端信息：" + tempReadString);}static void Send(Socket pSocket){//服务端向客户端发信息string tempSendInfo = Console.ReadLine();byte[] tempSendData = Encoding.UTF8.GetBytes(tempSendInfo);pSocket.Send(tempSendData);}}
}
