Socket(套接字)变成UDP

1.

 

 

 

1.创建socket
2.绑定一步写到位

分步骤写：

3.接受数据：需要开启线程，线程开启的是一个方法：

服务器端建立完毕

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace SocketUdp服务器
{
    class Program
    {
        public static Socket socketUdp;
        static void Main(string[] args)
        {
            //1.创建Socket
             socketUdp = new Socket(AddressFamily.InterNetwork,SocketType.Dgram,ProtocolType.Udp);
            //2.绑定本地Ip
            IPAddress iPAddress = IPAddress.Parse("10.0.208.54");
            EndPoint endPoint = new IPEndPoint(iPAddress, 7788);
            socketUdp.Bind(endPoint);
            //3.接收数据，需要开启线程
            Thread thread = new Thread(AcceptMessage);
            thread.Start();
            Console.ReadKey();

        }
        public static void AcceptMessage()
        {
            while (true)
            {

            EndPoint endPoint = new IPEndPoint(IPAddress.Any,0);
            byte[] data = new byte[1024];
            int length=  socketUdp.ReceiveFrom(data,ref endPoint);
            string mess=   Encoding.UTF8.GetString(data,0,length);
            Console.WriteLine("客户端发来消息"+mess);
            }
        }
    }
}

 

 

 建立客户端：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;

namespace 客户端Udp
{
    class Program
    {
        static void Main(string[] args)
        {
            //1.建立Socket
            Socket socketCline = new Socket(AddressFamily.InterNetwork,SocketType.Dgram,ProtocolType.Udp);
            //2.发送内容
            while (true)
            {

            string mess = Console.ReadLine();
            byte[] data=  Encoding.UTF8.GetBytes(mess);
            socketCline.SendTo(data,new IPEndPoint(IPAddress.Parse("10.0.208.54"),7788));
            }

            Console.ReadKey();
        }
    }
}

 

 

 运行步骤：先运行服务器端，再运行客户端
