采用udp协议 ,如何获取发送广播消息方的ip地址

 public void BroadCast()

        {

            udpclient = new UdpClient();//用本地ip地址和端口号0构造udpclient

            IPEndPoint ipendpoint = new IPEndPoint(IPAddress.Parse("255.255.255.255"),8000);

         

            string str_msg = "user" + StaticShareData.username + ":" + StaticShareData.GetLocalIp().ToString();

            byte[] buffer = Encoding.Unicode.GetBytes(str_msg);//ip地址          

            while (true)

            {

                try

                {

                    udpclient.Send(buffer, buffer.Length, ipendpoint);//向局域网内的电脑发送广播消息

                    Thread.Sleep(

                        1000);

                }

                catch

                {

                    //MessageBox.Show("广播出错","提示");

                }

            }

            

        }
