Summary

This chapter examined C# syntax for declaring and manipulating objects. You have seen how to declare static and instance fields, properties, methods, and constructors. You have also seen that C# adds some new features not present in the OOP model of some other languages: Static constructors provide a means of initializing static fields, whereas structs allow you to define high-performance types, albeit with a more restricted feature set, which do not require the use of the managed heap. You have also seen how all types in C# derive ultimately from the type System.Object, which means that all types start with a basic set of useful methods, including ToString().

Chapter 4, "Inheritance," examines implementation and interface inheritance in C#.
