Chapter 5
Advanced C# Class Construction
Techniques
This chapter rounds out your introduction to the core aspects of the C# language by
examining a number of advanced (but extremely useful) syntactic constructs. To begin,
you learn how to construct and use an indexer method. This C# mechanism enables you
to build custom types, which exposes internal subtypes using the familiar bracket
operator (i.e., []). If you have a C++ background, you will find that creating a C# indexer
method is analogous to overloading the [] operator on a C++ class. Once you learn how
to build an indexer, you then examine how to overload various operators (+, -, <, > and so
forth) for a custom C# type.
This chapter then examines three techniques that enable the objects in your system to
engage in bidirectional communications. First, you learn about the C# “delegate”
keyword, which is little more than a type-safe function pointer. Once you learn how to
create and manipulate delegates, you are in a perfect position to investigate the…
