Question

I want to catch all exceptions raised (handled or unhandled) to log them. for unhandled i use ThreadExceptionEventHandler and UnhandledExceptionEventHandler but i want to catch and exceptions that are in try catch block with or without (Exception e). It’s possible to inherit the exceptions class to create a general event?

Answer 1

Inheriting from Exception to provide your own Exception class would work fine for exceptions you generate in your code, and you could use the inner exception constructor to carry built in exceptions up the chain.

If you were goig to try that, you’d need to replace all of your exception handling code, and probably add a chunk more as well. I don’t think it’d be substantially better than Peter McG’s approach, but it might allow you different options when preserving & examining the original exceptions and re-throwing, for example keeping a record of whether it has already been logged lower down the chain.

Just to be explicit, it is possible to use:

catch (Exception e)
{
   log(e);
   throw;
}

which will rethrow the original exception.
