Summary

In this chapter you covered the last of the .NET Framework class library's standard I/O mechanisms. You started with a quick refresher on XML. You then examined how to read, validate, write, and update XML documents using forward-only access. Then you took a look at DOM trees and how to go about reading from, updating, and writing to them. Next, you took a brief look at the powerful XPath. You finished off by learning how simple it is to manipulate ADO.NET databases using XML.

Now with all four I/O systems covered, you should have no problems getting the information needed by your system into it.

In the next chapter, you move on to the world of the Internet and how to build ASP.NET applications using Managed C++.
