Summary

In this chapter, we've looked at collecting related information together into a structure that we can use to populate certain types of ASP.NET controls with information. While it would eventually become tedious to enter a great deal of information in this way, it is a useful technique when working with short lists or collections of data.

We have covered:

• Using arrays to store simple collections of data

• •ArrayLists, and the advantages they have over the simple array, including the ability to dynamically insert, add, and remove items from the collection

• Storing key-value pairs of data using a Hashtable and a SortedList

• What namespaces and classes are, and how the .NET Framework stores classes hierarchically in the .NET Framework

In the next chapter, we'll look at how to deal with problems that arise when errors occur in our applications.
