Thanks Cris,
Thanks for your quick and valuable information ,
My Answers
1. I already have an old DLL which does many things
including Ping , the ping function is openning Raw
socket.
2. That code is old C++ code (unmanaged).
I have three questions:
1. Is is possible to ping systems in same network domain
(LAN) without using RAw Sockets?
2. I am open to rewrite my ping specific code in C# but
tell me how to host it ? How will I make it Out process ?
3. What benifit I will get if I port my C++ code to C#
code in terms of performance and bugs.
Socket is in System.Net.Sockets Namespace not in
System.Web assembly.
Thanks in advance
