How to make broadcasting in C#

But what you need is using broadcasting with ICMP. Try understanding what broadcasting is with that link above.

For ICMP, you'll need to send a "PING" to the broadcast IP. Here's a few source codes to write your own PING program.

If you're using .NET Framework 2.0, there's a Ping utility class at the namespace System.Net.NetworkInformation which you can use. There is also an ICMP class available.

I hope that helps.
