C# OOP - Inheritance, Polymorphism, Interfaces

Explore object orientation through three pillars—classes as containers for logic, encapsulation via a simple public API, and object instantiation—illustrated with a zoo example of constructors, properties, and methods.

Learn object-oriented programming in C# by building classes and objects, properties and constructors, and explore polymorphism and inheritance through guitar, musician, and a console game.

Learn inheritance in c# oop: apply the is-a rule with animal as base for cat and dog, including abstract classes and single inheritance for code reuse.

Explore polymorphism through type substitution and dynamic binding, using base and derived classes with virtual and abstract members to tailor eating and start behavior in a zoo example.

Explore polymorphism in C# by building an inheritance hierarchy of vehicles and employees, overriding start and stop behaviors, and using abstract methods and dynamic binding to execute concrete class behavior.

Explore static classes and members, including utility classes like string utils, and static constructors. See why static classes cannot be instantiated or inherited, but can mix static and non-static members.

Explore static classes and static members through practical exercises, creating a static text animator, a static random utils class, and a static monster count to track instances.

Practice creating and wiring class libraries in C# by adding references, using statements, and namespaces, then reorganize types into utils and dungeons of doom core for a console game.

Compare reference types and value types, including how classes and structs differ and how boxing and unboxing work. Explain default values, nullable value types, and opt-in nullable reference types.
