What I would like to be able to do is take an ICriteria object (or IQuery) and dump the generated SQL to the screen or custom log (not log4...

Occasions when the using statement and IDisposable should never be used

Hi, I was reading about this scenario where making use of the C# using statement can cause problems. Exceptions thrown within the scope of the using block can be lost if the Dispose function called at the end of the using statement was to throw an exception also.

Other than setting a debug variable and incrementing it every time you start the foreach, when you break in with the visual studio debugger connected, is there any way to tell that this is the Xth time through the loop?
