UDPClient的用法

UDP_Server:

 

　　　　 UdpClient receivingUdpClient = new UdpClient(11000);
        IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Any, 0);
        try
        {
            byte[] sdata = Encoding.ASCII.GetBytes("dkasfjkdsjf");
            IPAddress ipa = IPAddress.Parse("192.168.97.30");
            receivingUdpClient.Receive(ref RemoteIpEndPoint);
            Console.WriteLine("远程：{0}",RemoteIpEndPoint.ToString());
            while (true)
            {
                receivingUdpClient.Send(sdata, sdata.Length, new IPEndPoint(RemoteIpEndPoint.Address, RemoteIpEndPoint.Port));
                System.Threading.Thread.Sleep(3000);
                Console.Write('.');
            }
        }
        catch (Exception e)
        {
            Console.WriteLine(e.ToString());
        }
 

UDP_Client

　　　　UdpClient udpClient = new UdpClient();
       udpClient.Connect("192.168.97.30", 11000);
       IPEndPoint ep = null;
       try
       {
           byte[] rddata = new byte[100];
           udpClient.Send(new byte[] { 0x31,0x32}, 2);
           while (true)
           {
               rddata = udpClient.Receive(ref ep);
               string aa = Encoding.ASCII.GetString(rddata);
               Console.WriteLine(aa);
           }

       }
       catch (Exception e)
       {
           Console.WriteLine(e.ToString());
       }
