GetFileLineNumber () returns 0, although I use a debug build

Question

I am using VS2010 to develop my project. In my code base, I use the stackframe GetFileLineNumber() function. However, at runtime, it always returns 0 . This happens even though I run a debug build. I also confirmed that the generated pdb file exists along with the generated executable.

Any ideas?

Yeah! I found the information running at the bottom of the MS help mail:

Turns out you should build your StackTrace instance like this:

 st = new StackTrace(true); 

true gets file and line information.
