Head First C# Code: Chapter 4, Types and References
Data type, database, Lieutenant Commander Data... it's all important stuff.
Without data, your programs are useless. You need information from your users, and you use that to look up or produce new information, to give back to them. In fact, almost everything you do in programming involves working with data in one way or another. In this chapter, you'll learn the ins and outs of C#'s data types, how to work with data in your program, and even figure out a few dirty secrets about objects (psstt… objects are data, too).
