Is there something comparable in C#?

No there is not. I believe On Error Resume Next still exists in VB.Net
because current VBers complained and wanted it in there. You really should
use a structured error handling rather than a GoTo, it takes getting used to
but it is much better method.

Most old VB code cannot be converted without the use of the On Error
commands. Hence its inclusion in VB.Net.
Fortunately, most of the VB programmers I've talked to are dead set against
using it in new projects.

Wow that got some fiery responses.
I do not wish to "write crappy code."
The problem is I have a routine
that pushes information out to servers (jobs to be more direct). The
user has the option to select multiple servers and push a tool out to
the servers. Each tool push is a single call to a sproc. My problem is
this, I wish the tools to be pushed out to the servers via a loop but I
do not wish to report errors until all the servers that have been
selected to receive the push actually do so (i.e. I would like to show
success/failures in a cumulative nature after the procedure has been
intiated). The reasoning behind this is that a failed push is likely and
should not force the whole action to fail.
Thanks,
Brandon

I didn't figure you did. Sorry if it sounded that way.
How about something like this aircode then?
//assumes collection of servers of some kind. Tweak to fit.
int nServers = servers.Count;
bool[] result = new bool[nServers];
for (int i = 0; i < nServers; i++){
try{
DoWork(servers[i]);
}
catch (Exception e){
result[i] = false;
//could log failure here or whatever using e
continue; //skips to next iteration.
}
result[i] = true;
}
for (int i = 0; i < nServers; i++)
Console.WriteLine("Was server #{0} successful? {1}", i, result[i] );
Keep Smilin'

I did find one issue with your example, Ed.
You cannot dynamically set an array size using
a variable other than a constant (i.e. the size
needs to be known at design time). The ArrayList
object is what I choose to overcome this limitation.
Thanks,
Brandon

If you want to write crappy code that ignores exceptions, you should switch to
VB. It's designed to let you shoot yourself in the foot faster than you can in
C# [1] ;-))
If you find yourself thinking you need to ignore an exception (or a whole
block of them, which is what On Error Resume Next does), why not post what you
are trying to do and get some help in restructuring your algorithm? 99.9% of
the time there will be a better way to do things, and it can help to have a
few extra sets of eyes looking at it.
If you don't want to switch to VB, but still insist on not handling
exceptions, you can always do this:
[1] C# equiv of On Error Resume Next
try{
//One line of crap code here that you will never know is failing.
}catch {}
try{
//Next line of crap code here that you will never know is failing.
}catch {}
