What do the “+n” values mean at the end of a method name in a stack trace?

Question

When reading a stack trace like:

[FormatException: Input string was not in a correct format.]
   System.Number.Strin         


        

Answer 1

I believe they're offsets into the code of the method - whether IL or JIT-compiled-assembly bytes, I'm not sure...

(Basically they're taking the place of line numbers, which of course aren't available without the pdbs.)
