Answer 1

Here's an excellent writeup for Windows sockets with code:

http://www.codeproject.com/KB/IP/Ping_and_Traceroute.aspx

It covers both ping and traceroute (which is what you're interested in).

Answer 2

you will send icmp (ping) to the address, each time you extend the ttl (time to live) by 1 - and that's how you get the trace.

here some library that helps you use ping in c#
