Get line number in exception

Question

Possible Duplicate:
C# Exceptions Not Giving Line Numbers

In C# winform, inside a catch block i have

Exception.ToString() -> to get exception information and line number of the code where the exception is thrown.

In dev. environment, i get the line number, whereas when the same EXE is deployed in the production, i don't get line numbers, any thoughts?

How do i get line #s in production environment? Even i tried StackTrace

class's GetFileLineNumber(), but it didn't bring me the line # in production environment.

You need to post the code you are having problems with. as it stands the question does not make that much sense... — MoonKnight, Sep 19 '12 at 15:44

The file name and line number are only available if debug symbols are loaded for the code that throws the exception. These symbols are in the .pdb files, which are usually not deployed with the assemblies in the production environment. If you deploy these files, you should get the line number information in the stack trace.

I have the program debug database (PDB) file along with the EXE, but still i don't see the line #. – Sharpeye500 Sep 19 '12 at 16:25
@Sharpeye500, are you sure that your PDB file matches the executable? – Thomas Levesque Sep 19 '12 at 16:30
Sorry my bad, it doesn't get installed, it was kept as a supporting file. How do i handle this? is there any dynamic code approach for this? – Sharpeye500 Sep 19 '12 at 16:39
@Sharpeye500, how do you handle what? You just need to deploy the PDB that was generated at the same time as the exe – Thomas Levesque Sep 19 '12 at 17:24

You need to have the PDB file in the same directory as the application in order to get this kind of information. Release builds generally aren't meant for debugging however, so I don't know why you would need this information from a release build.

In many cases some problems are hard to reproduce in the debug environment (especially race conditions). Having a line number really helps. Having said that, refactoring your code so that one method has exactly one responsibility can also help identify what might be the problem. – akhisp Sep 19 '12 at 15:49
