The Object Class
As indicated earlier, all .NET classes are ultimately derived from System.Object . In fact, if you don ’ t
specify a base class when you define a class, the compiler will automatically assume that it derives
from Object . Because inheritance has not been used in this chapter, every class you have seen here is
actually [...]

Constructors
The syntax for declaring basic constructors in C# is the same as in Java and C++. You declare a method
that has the same name as the containing class and that does not have any return type:
public class MyClass
{
public MyClass()
{
}
[...]

C# Programming Guidelines
The final section of this chapter supplies the guidelines you need to bear in mind when writing C#
programs.
Rules for Identifiers
This section examines the rules governing what names you can use for variables, classes, methods, and
so on. Note that the rules presented in this section are not merely guidelines: they are enforced by the [...]

Enumerations
An enumeration is a user - defined integer type. When you declare an enumeration, you specify a set of
acceptable values that instances of that enumeration can contain. Not only that, but you can give the
values user - friendly names. If, somewhere in your code, you attempt to assign a value that is not in the
acceptable [...]

Predefined Data Types
Now that you have seen how to declare variables and constants, let ’ s take a closer look at the data types
available in C#. As you will see, C# is much stricter about the types available and their definitions than
some other languages are.
Value Types and Reference Types
Before examining the data types in C#, [...]

This chapter gives you a good start in that direction by providing you with a basic knowledge of the
fundamentals of C# programming, which is built on in subsequent chapters. The main topics
covered are:
❑ Declaring variables
❑ Initialization and scope of variables
❑ Predefined C# data types
❑ Dictating the flow of execution within a C# program using loops [...]

The Role of C# in the . NET Enterprise Architecture
C# requires the presence of the .NET runtime, and it will probably be a few years before most clients —
particularly most home computers — have .NET installed. In the meantime, installing a C# application is
likely to mean also installing the .NET redistributable components. Because of that, [...]

A Closer Look at Intermediate Language
From what you learned in the previous section, Microsoft Intermediate Language obviously plays a
fundamental role in the .NET Framework. As C# developers, we now understand that our C# code will
be compiled into IL before it is executed (indeed, the C# compiler compiles only to managed code). It
makes sense, then, to [...]
