Icmp monitoring using visual c# .net

Question

I want to write an application that monitors some of my remote branches. I want to monitor 2 things

1) icmp drop (if i send 10 pings and 2 or more are dropped then alert) 2) if latency of ping is above 20 ms then alert.

I have just defined the rough thresholds. Can it be done in visual c#, Basically i am learning c# and also doing stuff for my office so that my learning is in right direction. If you guys can point me in right direction i will be grateful. I have seen ping class in .net (on google i mean) but i think it only tells whether the IP is up or not.

Kindly guide me

Answer 1

This is a fairly easy thing to do.

First you need the winpcap driver http://www.winpcap.org/ which you may already have if you have anything like wireshark installed.

Once you have the winpcap driver you then either need 'SharpPcap' the .NET library to interface to WinPcap:

or you can wrap it yourself using P/Invoke and other unmanaged goodies...
