Recommend tutorial on Exception Handling

[markknowsley]

Can anyone recommend a tutorial on exception handling in C# web forms? I'm especially interested in trapping SQL - related errors such as null values. I've had a trawl of the web but can't find anything that explains the concept particularly well.

First of all, the SQL related errors should not get in the code that is running the GUI. If you really want to learn something check out the MVC (Model-View-Controller) pattern at

http://www.enode.com/x/markup/tutorial/mvc.html

(or google). The errors would be "detected" in what is called the "business logic" of your application and only a comprehensive, language-dependent description of the incident would reach the GUI ( who's only business is to display information to the user, after all, and not to take decisions).

As for the exception management part, a nice article can be found here:
