Re: What if the Query String is empty?

"exceptions are handled" and "exceptions are not happening" 2 different things...

I did not say that user needs to get ASP.NET error screen with bunch of information if something is not integer.
But if user decided to play with QueryString by hand and put into ProductId his name instead of number he deserves to be redirected to the default.aspx how I do it in case of exception that is caught in Application_OnError

So it's perfectly OK to assume that ProductId is a number (if it's in database) and do a conversion without tipping-toeing around.

Are we back to this????

What if the sun will not come up tomorrow.....
Any programming is based on assumptions.... And it's good to have those assumptions.

Utter rubbish! Utter, utter garbage!

Robust programming (look it up on Google) is based on doing whatever you can to make sure that exceptions are handled.

Trying to instantiate an integer from something which cannot be converted into an integer will cause an exception.

Trapping for that eventualilty will not...
