Concepts of Encapsulation and Abstraction (C#)

In this chapter you will learn:

  • What is Encapsulation?
  • What is Abstraction?
  • What is the functionality of Encapsulation and Abstraction in C#?

Encapsulation and abstraction is essential part of C sharp programming that is mostly used for hide complex code from unauthorized user and shows only relevant information.

What is encapsulation?

Encapsulation is the process of hiding irrelevant data from the user. To understand encapsulation, consider an example of mobile phone. Whenever you buy a mobile, you don’t see how circuit board works. You are also not interested to know how digital signal converts into analog signal and vice versa. These are the irrelevant information for the mobile user, that’s why it is encapsulated inside a cabinet.

In C# programming, we will do same thing. We will create a cabinet and keep all the irrelevant information in it that will be unavailable for the user.

What is abstraction?

Abstraction is just opposite of Encapsulation. Abstraction is mechanism to show only relevant data to the user. Consider the same mobile example again. Whenever you buy a mobile phone, you see their different types of functionalities as camera, mp3 player, calling function, recording function, multimedia etc. It is abstraction, because you are seeing only relevant information instead of their internal engineering.



In this chapter you learned what is Encapsulation and Abstraction in C#. In next chapter, you will learn various types of access specifiers that are used to encapsulate code.
