Encapsulation and Polymorphism. C#, like all other object oriented languages support these features. Of the three core features of an object-oriented languages, inheritance is the most useful and most fascinating feature since it fosters code organization and reusability. Inheritance in OOP is similar ...
Applying polymorphism to functions this way is sometimes called function overloading.
