Core C# Programming Constructs,

Part I

T

his chapter begins your formal investigation of the C# programming language by presenting a

number of bite-sized, stand-alone topics you must be comfortable with as you explore the .NET

Framework. The first order of business is to understand how to build your program’s 

application

object and the composition of an executable program’s entry point: the Main() method. Next, you

will investigate the intrinsic C# data types (and their equivalent types in the System namespace)

including an examination of the System.String and System.Text.StringBuilder class types.

Once you know the details of the fundamental .NET data types, you will then examine a num-

ber of data type conversion techniques, including narrowing operations, widening operations, and

the use of the unchecked keyword. We wrap up this chapter by examining the core operators, itera-

tion constructs, and decision constructs used to build valid C# code statements.
