You must compile with debugging symbols (.pdb files), even in release mode, to get the line numbers (this is an option in the project build properties). share|improve this answer edited Oct 25 '12 at 11:53 bluish 9,3291269126 answered Mar 27 '09 at 2:47 Steven A.

In a production Release build, the file name and line number information doesn't exist. Also, the StackFrame object may be null in a release build, which would NullReferenceException to be thrown at runtime.Sadly, the StackTrace/StackFrame approach isn't complete replacement for __LINE__ and __FILE__ for someone who needs to report this kind of information in a production Release build.Mike RizziFriday, 13 June 2003 14:09:03 UTCDoesn't this only work with assemblies containing Debug information? Also any thoughts on this in context of obfuscated assemblies?Brian NantzSaturday, 14 June 2003 06:07:42 UTCTrue. You're pretty much SOL from what I can tell when in Release or obfuscated. Brent Rector would know all about the obfuscation stuff.
