    ASP.NET Basics Part 10: Making Exceptions - Endgame


    (Page 12 of 12 )

    And that's about it for this series. Over the last ten tutorials, I've attempted to introduce you to the basics of ASP.NET development, using simple examples and illustrations to explain the basics of the language to you. Among the things we've covered:

    1. A quick introduction to Microsoft's .NET vision, followed by the installation and configuration of the .NET SDK on a PC

    2. The anatomy of an ASP.NET script using ASP.NET HTML server controls

    3. Variables and simple data types

    4. Conditional expressions

    5. Different types of loops

    6. Multi-dimensional and jagged arrays

    7. Form submission with the GET and POST methods

    8. Functions

    9. Database interaction with ADO.NET;

    Finally, I wrapped things up with this final article, a gentle introduction to the ASP.NET exception handling mechanism. First, I showed you how to redirect the client to a simple error page when an exception is generated using the "web.config" file. Then, I demonstrated the "try-catch" exception handling construct, which can be used to easily trap and resolve exceptions within your script itself. Finally, I showed you how to throw your own custom exceptions, and tied it all up with a real-world example using nested "try-catch-finally" blocks.

    Of course, there's a lot more to learn in ASP.NET - and the following links should give you more than enough food for thought:
