.NET Forum / Languages / C# / September 2007Identifying function name
Is there some generic property that will give me the name of a function within its catch block? > Is there some generic property that will give me the name of a function > within its catch block? You can use the StackTrace class - but don't start building stack traces in performance critical code. If you're interested in what threw the exception, you can just use Exception.TargetSite.

What about this: ? http://msdn2.microsoft.com/en-us/library/system.reflection.methodbase.getcurrent method.aspx Are there any performance issues with that...?

It is probably faster than StackTrace though. Arne >>>> Is there some generic property that will give me the name of a function >>>> within its catch block?

I made a small test with: StackTrace GetCurrentMethod maintaining a special call stack via AspectDNG The timings were: StackTrace: 10,53125 GetCurrentMethod: 2,171875 AOP: 4,171875 So GetCurrentMethod is absolutely the fastest. But I would say its usability is limited because it does exactly what its name says so it can only be used in inline code not out in a special log/whatever method.

Not sure, to be honest - I only didn't mention it because I missed it :) SignatureJon Skeet - <skeet@pobox.com> http://www.pobox.com/~skeet Blog: http://www.msmvps.com/jon.skeet If replying to the group, please do not mail me too > Is there some generic property that will give me the name of a function > within its catch block? What are you trying to accomplish ? (when you write the code you know the function name) Arne I have a single error reporting method that takes the exception variable as its argument; so I don't know which method caused the exception but as detailes in the Jon Skeet's post, the exception variable holds the name. > > Is there some generic property that will give me the name of a function > > within its catch block?

Yes. And because you already have the exception, then there are very little overhead. Arne Free MagazinesGet these publications absolutely FREE for up to 12 months.
