Yep!

As of right now, there has not been a new release created with that fix in it. You'll have to download the source and recompile.

I got the same problem with infinite timeout when server is not responding. I use downloaded library. Should I get source code and recompile with above patch or there will be a new precompiled version of library?

Change the line:

_port = (

ushort)IPAddress.NetworkToHostOrder(BitConverter.ToUInt16(port, 0));

to:

_port = (

ushort)IPAddress.NetworkToHostOrder((short)BitConverter.ToUInt16(port, 0));

otherwise the returned port is always 0.

I suspect it would...there's nothing too fancy in the code. If you are able to give it a shot, let me know if it works or not. If I can get around to it, I'd be interested to try this out as well...

Really! I expected there would be a default timeout of some sort (not infinite!)....thanks for the info on adjusting it on the underlying socket! I'll adjust the code here accordingly.

I appreciate the work you put into this. We were just talking about implementing something like this in-house. You saved us some time! I had one issue come up while using it though. I had a situation where a DNS server didn't exist or wasn't properly set, so the UDP Receive function would hang indefinitely. I changed your code to take in a timeout_ms parameter in the Resolve function, and I set the underlying socket receive timeout to use it so everything could dispose properly when it timed out. Works like a charm now! Thanks!

Here's a snippet

UdpClient udpClient = new UdpClient();
try
{
udpClient.Connect(ipep);
udpClient.Send(bDnsQuery, bDnsQuery.Length);

udpClient.Client.ReceiveTimeout = timeout_ms; //added socket timeout here.
recvBytes = udpClient.Receive(ref ipep);

}
finally
{
udpClient.Close();
}
