Question

Say I have a method like this:

public void SaveData()
{
   try
   {
        foreach (var somevar1 in list.SomeType1s)
        {
            CEData.SaveRow(sometype1)
        }    
        foreach (var somevar2 in list.SomeType2s)
        {
            CEData.SaveRow(sometype2)
        }    
        foreach (var somevar3 in list.SomeType3s)
        {
            CEData.SaveRow(sometype3)
        }    
        foreach (var somevar4 in list.SomeType4s)
        {
            CEData.SaveRow(sometype4)
        }    
        foreach (var somevar5 in list.SomeType5s)
        {
            CEData.SaveRow(sometype5)
        }    
   }
   catch (Exception e)
   {
     logger.DebugException("Rollback Occured with the following stack trace: \r\n" 
         + e.StackTrace, e);
     Rollback();
     throw;
   }
}

is there a way to know in the catch portion what line I got to? My stack trace will just say that it was in the method SaveData(), but not which line failed.

I could go an add logging in between each line, but I would rather not (for various release of debug code reasons).

So, I thought I would ask. Is it possible to know what line was being executed when the exception was thrown?

More Info:

Looks like line numbers should come standard. The only reason I can see that I am not getting them is that I am doing Windows Mobile and Compact Framework development. So maybe they are not included in the compact framework? (My project has “full” set for the Debug Info Output.)

Answer 1

Nope, the Compact Framework doesn’t give that info. Refactor the SaveData into private methods for each of the for loops, then you’d at least narrow it that far (by method name or input parameter).
