Overview

Now that you understand a little more about what C# can do, you will want to learn how to use it. This chapter on the basics of C# will give you a good start in that direction by providing you with a basic knowledge of the fundamentals of C# programming, which we will build on in subsequent chapters. The main topics we will be covering are:

• Declaring variables

• Initialization and scope of variables

• C#'s predefined data types

• Dictating the flow of execution within a C# program using loops and statements

• Calling and declaring classes and methods

• Using arrays

• Operators

• Type safety and how to convert between data types

• Enumerations

• Namespaces

• The Main() method

• Basic command-line C# compiler options

• Using System.Console to perform console I/O

• Using commenting features in C# and Visual Studio .NET

• C# identifiers and keywords

By the end of this chapter you will know enough C# to write simple programs, though without using inheritance or other object-oriented features. We will be exposing these details in the next few chapters of the book.
