List of Tables
Therefore, in this book, I have deliberately chosen to avoid creating examples that tie the example code to
a specific industry or vein of programming. Rather, I choose to explain C#, OOP, the CLR, and the .NET
base class libraries using industry-agnostic examples. Rather than having every blessed example fill a grid
with data, calculate payroll, or whatnot, I'll stick to subject matter we can all relate to: automobiles (with
some geometric structures and employees thrown in for good measure). And that's where you come in.
My job is to explain the C# programming language and the core aspects of the .NET platform the best I
possibly can. As well, I will do everything I can to equip you with the tools and strategies you need to
continue your studies at this book's conclusion. Your job is to take this information and apply it to your
specific programming assignments.
I obviously understand that your projects most likely don't revolve around automobiles with pet names;
however, that's what applied knowledge is all about! Rest assured, once you understand the concepts
presented within this text, you will be in a perfect position to build .NET solutions that map to your own
unique programming environment.

LiTsth oisf cThaabpletser begins by examining how interface-based programming techniques can be used to build an
event-based system. This will function as a point of contrast to the meat of Chapter 7: the delegate type.
Simply put, a .NET delegate is an object that "points" to other methods in your application. Using this
pattern, you are able to build systems that allow multiple objects to engage in a two-way conversation.
After you examine the use of .NET delegates, you are then introduced to the C# "event" keyword, which is
used to simplify the manipulation of raw delegate programming.
Chapter 8: Advanced C# Type Construction Techniques
The final chapter of this section completes your study of the C# programming language by introducing you
to a number of advanced programming techniques. For example, here you learn how to overload
operators and create custom conversion routines (both implicit and explicit), as well how to manipulate C-
style pointers within a *.cs code file. This chapter also takes the time to explain how these C#-centric
programming constructs can be accessed by other .NET programming languages (such as Visual Basic
.NET), which is a natural lead-in to the topic of .NET assemblies.
