From Beej's Guide to Network Programming:

How can I set a custom timeout value for a TCP or UDP socket?

It depends on your system. You might search the net for SO_RCVTIMEO and SO_SNDTIMEO (for use with setsockopt()) to see if your system supports such functionality.

The Linux man page suggests using alarm() or setitimer() as a substitute.

I'm interested in implementing a socket timeout using setitimer(), is there any sample code that does that? Thanks.

Socket client = new Socket(AddressFamily.InterNetwork,
SocketType.Dgram, ProtocolType.Udp);
client.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReceiveTimeout, 5000);

So SocketOptionName has ReceiveTimeout/SendTimeout. Hope this will help you.
