What is abstraction in C#? Explain in details.

Question

Rajanikant Hawaldar · Answer

Hello Anand, " Abstraction " simply means showing only those details to the user, which are of use to them. Abstraction refers to the act of representing essential features without including the background details or explanations. 1) Abstraction is concerned with hiding, or providing detail at a later date. A class that is abstracted is something where you provide an interface that have to be implemented within the class, but that class itself contains no implementation itself. 2) The best software abstractions make complex things simple. They do this by ruthlessly hiding away unessential aspects of a class. These unessential aspects, once truly hidden away, cannot then be seen, used, or depended upon in any way. 3) Abstraction defines way to abstract or hide your data and members from outside world. Simply speaking Abstraction is hiding the complexities of your class or struct or in a generic term Type from outer world. This is achieved by means of access specifiers. (Interview Definition: - Hiding the complexities of your type from outside world.) Public -- Accessible outside the class through object reference. Private -- Accessible inside the class only through member functions. Protected -- Just like private but Accessible in derived classes also through member functions. Internal -- Visible inside the assembly. Accessible through objects. Protected Internal -- Visible inside the assembly through objects and in derived classes outside the assembly through member functions. https://www.c-sharpcorner.com/UploadFile/4624e9/abstraction-in-C-Sharp

Abstraction allows making relevant information visible and encapsulation enables a programmer to implement the desired level of abstraction. Abstraction can be achieved using abstract classes in C#. C# allows you to create abstract classes that are used to provide a partial class implementation of an interface. for more details please refer below links Shiv Prasad Koirala Sir Video. https://youtu.be/0EnSPBVrbG0 OR Kudvenket video https://www.youtube.com/watch?v=7amjs2y_dgo https://www.youtube.com/watch?v=yyU3bXyc_oU https://www.geeksforgeeks.org/c-sharp-abstraction/ https://www.c-sharpcorner.com/UploadFile/4624e9/abstraction-in-C-Sharp/

Abstraction is "To represent the essential feature without representing the background details." Abstraction lets you focus on what the object does instead of how it does it. Abstraction provides you a generalized view of your classes or objects by providing relevant information. Abstraction is the process of hiding the working style of an object, and showing the information of an object in an understandable manner. Real-world Example of Abstraction Suppose you have an object Mobile Phone. Suppose you have 3 mobile phones as in the following: Nokia 1400 (Features: Calling, SMS) Nokia 2700 (Features: Calling, SMS, FM Radio, MP3, Camera) Black Berry (Features:Calling, SMS, FM Radio, MP3, Camera, Video Recording, Reading E-mails) Abstract information (necessary and common information) for the object "Mobile Phone" is that it makes a call to any number and can send SMS. Abstraction means putting all the variables and methods in a class that are necessary. For example: Abstract class and abstract method. Abstraction is a common thing.

Abstraction is one of the principle of object oriented programming. It is used to display only necessary and essential features of an object to ouside the world. Means displaying what is necessary and encapsulate the unnecessary things to outside the world. Hiding can be achieved by using "private" access modifiers. Outside the world means when we use reference of object then it will show only necessary methods and properties and hide methods which are not necessary.

Abstraction: In simple word we can say abstraction is provide the functionality for future implementation. example we have a company which provide some service we Incluse some services into the broucher while company started so we include or add more services while we enhanncing the company this is called abstarction. i belive i have provide you a good example for understanding the abstraction.

Rajeev Kumar · Answer

In Abstraction, by using access modifiers, we can hide the required details of the object and expose only necessary methods and properties through an object's reference . In real-time, the laptop is a perfect example of abstraction in c#.
