UDP接收...public void ReceiveMessage()
        {
           //在本机指定的端口接收
            IPEndPoint remoteIpEndIPoint = new IPEndPoint(IPAddress.Any,1000);
            udpReceive = new UdpClient(remoteIpEndIPoint);
            IPEndPoint iep = new IPEndPoint(IPAddress.Any, 0);
            //接收从远程主机发送过来的信息
            while (true)
            {
             //ref表示引用类型的 IPPoint实例接收消息
                byte[] receiveBytes = udpReceive.Receive(ref iep);
               for (int i = 0; i < receiveBytes.Length; i++)
                {
                    RetStr += String.Format("{0:X2} ", receiveBytes[i]);
                }
               MessageBox.Show(RetStr);
            }
        }

UDP发送...            udpSend = new UdpClient();////初始化UdpClient
            IPEndPoint iep = new IPEndPoint(IPAddress.Parse("192.168.123.168"), 10006);
            byte[] bytes = System.Text.Encoding.UTF8.GetBytes(this.textBox3.Text);
                //设置重传次数 
                int retry = 0;
                while (true)
                {
                    
                        //发送组播信息
                        udpSend.Send(bytes, bytes.Length, iep);
                        break;
                                       
                        if (retry < 3)
                        {
                            retry++;
                            continue;
                        }
                        else
                        {
                            DialogResult result = MessageBox.Show("发送失败！");
                            break;
                        } 
               
            }
