Beginning C# 2008 Objects: From Concept to Code

13.1. Namespaces

Throughout the examples in Parts One and Two of this book, and in most of the examples to follow, we've commonly placed a using statement (more formally referred to as a using directive) at the top of our programs to allow us to access the elements of a particular namespace by their simple names. By way of review, a namespace is a logical grouping of related programming elements, as was briefly discussed in Chapter 1; the .NET Framework libraries are so vast that namespaces are used to divide the libraries up into more manageable sublibraries.

A simple name is the name of the class as it appears in the class declaration; for example:

// This class has the simple name "Student".
public class Student {
  // Details omitted.
}
