In this chapter, you’ll deepen your understanding of the C# programming language by examining a number of more advanced syntactic constructs. To begin, you’ll learn how to implement and use an indexer method. This C# mechanism enables you to build custom types that provide access to internal subitems using an array-like syntax. After you learn how to build an indexer method, you’ll see how to overload various operators (
>, and so forth), and how to create custom explicit and implicit conversion routines for your types (and you’ll learn why you might want to do this).
Next, you’ll examine topics that are particularly useful when working with LINQ-centric APIs (though you can use them outside ...
