Using Objects in ASP.NET

Objects and object-oriented programming have been around for a long time in mainstream desktop and client/server programming. Traditionally, web development has been dominated by procedure-based scripting languages. It is only recently that OOP has begun to integrate into the web programming world. Languages used to create dynamic websites such as Java, Perl, PHP, and Coldfusion have begun to implement object-orientation into their feature sets or improve upon the OOP features they already had. In ASP 3.0, objects could be manipulated or created through COM and VBScript. In ASP.NET, Microsoft has brought ASP to a new level of "object orientedness" not previously seen in web programming languages.

Perhaps you've been using ASP.NET for a while and you're not sure if you're doing everything right when it comes to this OOP stuff. Or perhaps you're still writing ASP.NET code primarily in a script fashion similar to ASP 3. In this article, Craig Bowes discusses how to use OOP features in your ASP.NET web applications.

Bowes lays the groundwork for writing object-oriented components in web applications. He reviews the different levels of access you can give classes and their methods, shows you how to use Get/Set blocks within properties, and demonstrates how simple it is to instantiate and use objects within .aspx pages.
