Hi y'all,

I posted this as an add on to another post so I thought I'd repost it here.

How do I identify an event programmatically?

Is it necessary to do a

if(e.message=="<Event description>" ) ...

to identify the particular event?

Thanx,
Bill

The best thing is to only subscribe events you're interested in, and
use different handlers for each of the events you want to handle
differently - that way you don't need to test in your code.
 
I am not clear on how to subscribe on a particulat event. Alright, in this
case, the exception a System.ArgumentException and I can catch it. But my
question is, given a System.ArgumentException, will the message property
always be the same could there be a range of exceptions within this? I
suspect the latter, so all I can do is catch a category of exceptions and
not act on a specific exception which I may want to ignore unless I check
the message property..

Ah, you were talking about exceptions rather than events? In that case,
I suggest you only catch the right kind of exception:

catch (ArgumentException e)
{
....
}

And no, the message of an exception won't always be the same.
