Socket编程（一）

一 ：通过Tcp进行通信（阻塞方式）

Server:

1.创建套接字Socket

2.创建绑定的IP+Port(端口号)

3.绑定IP+Port

4.监听

5.接收连接

6.发送数据

7.接收数据

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net.Sockets;
using System.Net;
namespace ServerSocket
{
    class Program
    {
        static void Main(string[] args)
        {
            
            //创建套接字
            Socket serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            //IpEndPoint
            IPAddress ip = IPAddress.Parse("127.0.0.1");
            IPEndPoint ipEndPoint = new IPEndPoint(ip, 7788);
            //绑定
            serverSocket.Bind(ipEndPoint);
            //监听
            serverSocket.Listen(10);
            //接收连接
            Socket clientSocket = serverSocket.Accept();
            //发送数据
            string message="Hello 欢迎";
            byte[] data=Encoding.UTF8.GetBytes(message);
            clientSocket.Send(data);
            

            byte[] data1=new byte[1024];
            int len = clientSocket.Receive(data1);
            string message1 = Encoding.UTF8.GetString(data1, 0, len);
            Console.WriteLine(message1);

            Console.ReadKey();
        }
    }
}

Client：

1.创建套接字

2.创建绑定的IP+Port(端口号)  （这个指的是你要连接的服务器的端口号）

3.连接10.181.245.87

4.接收数据

5.发送数据

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net.Sockets;
using System.Net;
namespace ClientSocket
{
    class Program
    {
        static void Main(string[] args)
        {
            //创建套接字
            Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            //连接
            IPAddress ip=IPAddress.Parse("127.0.0.1");//目标Ip
            IPEndPoint ipEndPoint=new IPEndPoint(ip,7788);
            clientSocket.Connect(ipEndPoint);//阻塞方法
            //接收数据
            byte[] data = new byte[1024];
            int len = clientSocket.Receive(data);
            string message = Encoding.UTF8.GetString(data, 0, len);
            Console.WriteLine(message);

            string message1 = Console.ReadLine();
            byte[] data1 = Encoding.UTF8.GetBytes(message1);
            clientSocket.Send(data1);


            Console.ReadKey();

        }
    }
}
