Chapter 4. Variables and Data Types


Data manipulation is the heart of any software application. You could choose to process the data the way that your computer's CPU does: bit by bit. But that quickly becomes tedious, so languages like Visual Basic include a variety of data types , implementations of data management tools each based on a subset of possible data values. This chapter discusses data types, the data managed by those types, and how they are processed in Visual Basic and .NET.

The term "data types" differs from the more general term "types" used throughout this and other .NET documentation. .NET is built on the concept of the type, the basic data construct of .NET, which includes classes, structures, delegates, and other high-level elements used to build applications and pass data around programs. The data types available in .NET are built from these more generalized types, as are your own custom classes. Data types provide a small but essential set of data manipulation tools, grouped by the subset of possible data values managed by each data type.
