C# Objects

Object-Oriented Programming

We'll discuss some of the basics concepts of object oriented programming and exactly what it means to be "object oriented". We'll learn the differences between objects and classes. Then we'll see how to create classes and objects in C#. 13 steps

Inheritance

We'll learn about one of the four core principles of OO: inheritance. We'll also learn how inheritance is used to create and handle custom exceptions. 12 steps
