Question

What are the best practices to consider when catching exceptions and re-throwing them? I want to make sure that the Exception object\'s InnerException

Answer 1

The rule of thumb is to avoid Catching and Throwing the basic Exception object. This forces you to be a little smarter about exceptions; in other words you should have an explicit catch for a SqlException so that your handling code doesn't do something wrong with a NullReferenceException.

In the real world though, catching and logging the base exception is also a good practice, but don't forget to walk the whole thing to get any InnerExceptions it might have.
