Abstract

The chapter delves into the core mechanics of inheritance and polymorphism, essential pillars of object-oriented programming (OOP). It begins by explaining the 'is-a' relationship and how it facilitates code reuse. The text then explores the use of protected members and the sealed keyword to control access between base and derived classes. Additionally, it covers the details of the System.Object class and how to override its methods for custom behavior. The chapter also introduces record types and their support for inheritance in C# 9.0. Throughout, the text provides practical examples and insights, making it an invaluable resource for developers looking to deepen their understanding of OOP principles.
