Exceptions after compile to Release

I am working with Exceptions and have found a bit of a problem for me.
Using the code below in Debug I get the info I want which is basically:
-Line of error
-Column of error
-Method where error happened

However, when you compile to Release version you get no line or column
numbers. So I assume this is because the .pdb file holds all of the info
regarding the lines and columns or something to that order. I am not
really to sure what the .pdb file actually holds.

So what I am after is a way to track down the exact place the error
happened without having to put a try...catch block everywhere in my
code. Am I going about this all wrong?

Also please note the code below is simply me playing and is in no way
complete or even ready for release. Also I should note that I am running
this by pressing F5 in VS.Net 2003 with DotNet Framework 1.1.

TIA

Well after some research I have found that what I want to do is not
actually possible. I guess I can live with the method that the error is
in using the "GetMethod" method, but what about the page? Below is what
I have come up with as a guide to what can be used as far as the methods
of the StackFrame. Hope it saves someone the trouble I went through.

Equals (inherited from Object) - Debug and Release
GetFileColumnNumber - Debug Only
GetFileLineNumber - Debug Only
GetFileName - Debug Only
GetHashCode - Debug and Release
GetILOffset - ???
GetMethod - Debug and Release
GetNativeOffset - ???
GetType - Debug and Release
ToString - Debug and Release
