Well it will be just as tricky as it was in regular/unmanaged C++.
Use the Socket class and set it up for that kind of transmission protocol.

Something like this I suppose?
[code=c#]
System.Net.Sock ets.Socket s = new System.Net.Sock ets.Socket(Syst em.Net.Sockets. AddressFamily.I nterNetwork, System.Net.Sock ets.SocketType. Raw, System.Net.Sock ets.ProtocolTyp e.Icmp);
[/code]

"plz" look it up yourself. We are not going to do you work for you.
Look up the documentation of ICMP calls and you should be able to figure it out.
