I am trying to create some sort of error catching method that will return the error line number. We have an abort email that is sent out when a process aborts that gives us the err.number and err.description but I would like to know where is actually errors out.

I know you can do the following:

1: code here
2: code here
3: code here

etc. and use ERL to get the number but it would be tedious to type each line out like that.

Is there either a way to automatically do this or would it be easier to use Stacktrace? If Stacktrace is better could you please show me an example?

    Generating line numbers in exception stack traces is a built-in feature for the CLR. You do however have to provide the information it needs to map a code address to a line number. Switch to the Release configuration of your project. Project + Properties, Compile tab, Advanced Compile Options. Change the “Generate debug info” setting from pdb-only to Full. Deploy the .pdb files along with your program.

    Beware that the line number you get is always an estimate so do not blindly trust what you see. The mapping is imperfect due to the jitter optimizer inlining methods and otherwise moving code around to make the program run faster.
