Success !!! here's what I did
Code:
--------------------
int UDPPort = 3483;
UdpClient listener = new UdpClient(UDPPort);
IPEndPoint ReceiveIP = new IPEndPoint(IPAddress.Any, UDPPort);
// Notice I escape the 0 terminator.
Char[] request = {
'e',
'I', 'P', 'A', 'D', '\0',
'N', 'A', 'M', 'E', '\0',
'J', 'S', 'O', 'N', '\0',
};
Byte[] RequestData = Encoding.ASCII.GetBytes(request);
listener.Receive(ref ReceiveIP); // This populates ReceiveIP with the ip
address of the server that responded.
int BytesSent = listener.Send(RequestData, RequestData.Length, ReceiveIP); //
Now send our request.
byte[] BytesReceived = listener.Receive(ref ReceiveIP); // Get the response
data ( "ENAME\bmax2playJSON9000" is returned in a byte array )
String RetVal = Encoding.ASCII.GetBytes(BytesReceived);
// The port number is all the digits following JSON which is easily parsed
--------------------
thanks for your help.
We can't stop here this is bat country. RIP Hunter S Thompson.
