How to stop custom ThrowHelper from your StackTrace?

Question

The sample you will find in the .net base class library is the ThrowHelper template. In essence, it reduces the number of byte codes for each method.

Anyway, I was wondering if an attribute directive exists to stop the error caused by calling throw helper inside the helper. I would prefer the debugger to stop at the calling line.

i.e.

ThrowHelper.ThrowAnException () 

not inside ThrowAnException ()

Answer 1

You can also mark your attribute throwing method:

 class ThrowHelper { [DebuggerStepThrough] public static void Throw() { throw new InvalidOperationException(); } } 

Then the debugger will not introduce this method.

Answer 2

You could make a helper method really not an exception, just create it. The stack trace will point to the throw statement in your real method, and not to anything in ThrowHelper.

 throw ThrowHelper.CreateAnException();
