No. Your point is hard to understand. For C#, this is the same as to ask "why do we have to breath? where we breath?".

C# is purely object-oriented language, it is designed the way that you virtually cannot write anything without classes. To write a single method, you already need it to be a method in a class or a structure.

If you need to understand why people invented classes, why those classes have been introduced in computer science and computing practice, what are the benefits or downsides of OOP, giving you one or few Quick Answers would be totally useless. You need to read some literature on OOP, to get some basic ideas. Well, programming by extension, encapsulation, abstraction, late binding, polymorphism, open-close principle, all those things. However, reading one good book with understanding, reinforced be some practice, would be enough to catch up.
