Recreating Ping in .Net Problems

[Jason Rodman]

I have downloaded every example on how to create a ping utility in .Net in
both VB and C#, but have been disappointed with the results. I have YET to
find an example that returns consistent results that are even close the the
actual ping command line utility. For example:

If i would ping the same server over and over, some pings would come back in
0 milliseconds, others would come back in 15, but never in between. It would
always jump between the two. The real ping utility would consitently return
in 5-6ms for the same host but I could never get that kind of precision or
consistency. What does the real ping utility do different to get those kind
of results?

Any thoughts?

Well, you could always use the commandline ping, hack that this idea is..

exec master..xp_cmdshell 'ping www.server.com'

or shell ping www.server.com > out.txt

Jason,
I went through this mess recently. Send me your email address and I'll send
you some code. It may be what you already have but it's worth a look.

I recall trying out an open source ICMP implementation done using C# and it
seemed nice and quite stable.

Hope this helps,
