Using the .NET Collection Classes Part 2

This tutorial is the final part of a 2 part series on .NET Collections, and focuses on a real world use for the ArrayList class. It will demonstrate how to use an ArrayList collection to display all the image files stored in a directory as well as display each image file’s associated file information. The display layout of the images and data is handled using a DataList control. The image browser will also utilize classes in Namespaces other than System.Collections to incorporate paging, providing the end user with a mechanism to view a specific number of images per page view and also to display image specific file system information.
