The Weird and The Wonderful

   

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrassing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

I am sorry you do not fully understand what I wrote.

First, I did show that constructor exceptions are "swallowed", though I do admit that is a subjective term. To be more precise, constructor exceptions occur outside the MSIL exception handling. In order to catch the constructor exception, the "using" has to be wrapped in a try-catch of its own.

Second, because of what I just explained, the unit test that implements "using" needs the outer try-catch, while the other approach does not. The "using" approach results in nested try-catches, which is why it creates more lines of code to be executed. The coding for the unit tests is correct "as-is". The outer try-catch in your version of the StandardUsageTest() method is unnecessary.

Third, the execution time is not the point. I ran them several times, to account for any caching, and the time relationship remains the same. The point is that a very popular C# coding shortcut results in more lines of code to be executed (MSIL) than the other approach, and forecloses the opportunity to capture runtime values in the exception's Data dictionary within the MSIL code.

If you want to stick with the "using" statement, then do so. I am not trying to tell you or anyone else what they should do. I am presenting information for the "what" and "how" so that an objective person can decide for themselves. I provided the details, as was asked, and it completely and rationally supports my thesis. If you agree, fine. If you disagree with rational reasons you can explain, then educate us all. But since you are disagreeing without a rational basis, that is fine. You should continue to do things the way you think is best. But if you don't like my approach, just admit it is a personal preference to stick with the "using" statement. For example, if benefitting from more advanced exception handling does not provide a value for you, then implementing the "using" statement makes sense.
