C# Exception Line Number Is Always Zero (0)

Question

I published my project in debug mode and put both dll and pdb files in my server,
now i want to get exception line number using these codes :

   System.Diagnostics.StackTrace trace = new System.Diagnostics.StackTrace(ex, true);
   Response.Write("Line: " + trace.GetFrame(0).GetFileLineNumber());

but i don't know why line number of exception is always zero -> 0
how can i fix it?

Just use `ex.ToString()` instead of messing around with the stack trace and frames yourself. — Oded, Jan 16 '13 at 10:06
dear dash, i saw that link - but problem still exists in release mode! — SilverLight, Jan 16 '13 at 10:11
`ex.ToString()` returns the whole StackTrace, not only the line the exception has been thrown. — Carsten, Jan 16 '13 at 10:56

Try

System.Diagnostics.StackTrace trace = new System.Diagnostics.StackTrace(ex, true);
var stackFrame = trace.GetFrame(trace.FrameCount - 1);
var lineNumber = stackFrame.GetFileLineNumber();

Doesn't `trace.GetFrame(trace.FrameCount - 1)` get the most ancestral frame (and therefore line) of code in your application's main method? (or just before the call to main in the system code?) – Jesse Chisholm Jan 14 '16 at 22:11
Didn't work in my case, still 0 – Amitai Weil Feb 05 '23 at 13:16
