Advanced C# Class Construction Techniques

Abstract

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.
