c#UDP协议

UDP协议是不可靠的协议，传输速率快

服务器端：

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

using System.Net.Sockets;
using System.Net;
using System.Threading;

namespace UDPServer
{
    class Server
    {
        private Socket _ServerSocket;                       //服务器监听套接字
        private bool _IsListionContect;                     //是否在监听

        public Server()
        {
            //定义网络终节点（封装IP和端口）
            IPEndPoint endPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"),);
            //实例化套接字
            _ServerSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
            //服务端绑定地址
            _ServerSocket.Bind(endPoint);

            EndPoint ep = (EndPoint)endPoint;

            while (true)
            {
                //准备一个数据缓存
                byte[] msyArray = new byte[ * ];
                //接受客户端发来的请求，返回真实的数据长度
                int TrueClientMsgLenth = _ServerSocket.ReceiveFrom(msyArray,ref ep);
                //byte数组转字符串
                string strMsg = Encoding.UTF8.GetString(msyArray, , TrueClientMsgLenth);
                //显示客户端数据
                Console.WriteLine("客户端数据：" + strMsg);
            }
        }

        static void Main(string[] args)
        {
            Server obj = new Server();
        }
    }
}

客户端：

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

using System.Threading;
using System.Net;
using System.Net.Sockets;

namespace UDPClient
{
    class Client
    {
        private Socket _ClientSocket;                       //客户端通讯套接字
        private IPEndPoint SeverEndPoint;                   //连接到服务器端IP和端口

        public Client()
        {
            //服务器通信地址
            SeverEndPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), );
            //建立客户端Socket
            _ClientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);

            EndPoint ep =(EndPoint) SeverEndPoint;

            while (true)
            {
                //输入信息
                string strMsg = Console.ReadLine();
                //退出
                if (strMsg == "exit")
                {
                    break;
                }
                //字节转换
                Byte[] byeArray = Encoding.UTF8.GetBytes(strMsg);
                //发送数据
                _ClientSocket.SendTo(byeArray,ep);
                Console.WriteLine("我：" + strMsg);
            }
            //关闭连接
            _ClientSocket.Shutdown(SocketShutdown.Both);
            //清理连接资源
            _ClientSocket.Close();
        }

        static void Main(string[] args)
        {
            Client obj = new Client();
        }
    }
}
