  It's very simple to make same thing in C# Server: var Server = new UdpClient(8888); var ResponseData = Encoding.ASCII.GetBytes("SomeResponseData"); while (true) { var ClientEp = new IPEndPoint(IPAddress.Any, 0); var ClientRequestData = Server.Receive(ref ClientEp); var ClientRequest = Encoding.ASCII.GetString(ClientRequestData); Console.WriteLine("Recived {0} from {1}, sending response", ClientRequest, ClientEp.Address.ToString()); Server.Send(ResponseData, ResponseData.Length, ClientEp); } Client: var Client = new UdpClient(); var RequestData = Encoding.ASCII.GetBytes("SomeRequestData"); var ServerEp = new IPEndPoint(IPAddress.Any, 0); Client.EnableBroadcast = true; Client.Send(RequestData, RequestData.Length, new IPEndPoint(IPAddress.Broadcast, 8888)); Client.Receive(ref ServerEp); var ServerResponseData = Client.Receive(ref ServerEp); var ServerResponse = Encoding.ASCII.GetString(ServerResponseData); Console.WriteLine("Recived {0} from {1}", ServerResponse, ServerEp.Address.ToString()); Client.Close();
