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ipconfignetstat -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

}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);}}
}Socket 代码解析
AddressFamily: InterNetwork 使用IPv4 InterNetworkV6 使用IPv6
SocketType
