When we use abstract class

Question

Mahesh Chand · Answer

Abstract classes are created by class library owners/creators who wants certain functionality implemented by the developers who wants to inhertite his/her class library classes. Abstract classes don't implement any functionality. They just define certail abstract members that must be implemented by the derived classes. In typical Windows and Web applications, you will probably never use abstract classes, unless you're building libraries and components.

Abstract class can be created when we want to move the common functionality of 2 or more classes into base class and where the base class not to be instantiated.

Abstract class is special kind of class, which will allow sub classes must implement the abstract methods. If abstract class contains non abstract methods then there is not must implementation condition for them.

Ranjit Powar · Answer

Abstract class used to share common functionalities with different implementation in child parent class relation. In abstract class there is abstract method (only declaration) which can be implemented by child classes. Check here http://knowledgetpoint.com/csharp/abstract-class-methods/

Ankit Sharma · Answer

If we don't want a class to be instantiated,we define it as abstract. Abstract classes can be inherited though. An abstract class can have abstract and non abstract methods. If a method is defined as abstract, it must be implemented in derived class .

I think you will easily find this answer on google. When two classes share the same properties or method the common denominator is your abstract class. Please visit below link: https://msdn.microsoft.com/en-in/library/scsyfw1d(v=vs.71).aspx

An abstract class is a just like a template/definition of methods and variables of a class that contains one or more abstracted methods. Abstract classes are used in all common object-oriented programming (OOP) languages (C++, C# and VB.NET, Java). Objects or classes may be abstracted, which means that they are summarized into characteristics that are relevant to the current program’s operation. // Abstract class abstract class Animal { // Abstract method (does not have a body) public abstract void animalSound(); // Regular method public void sleep() { Console.WriteLine("Zzz"); } } // Derived class (inherit from Animal) class Pig : Animal { public override void animalSound() { // The body of animalSound() is provided here Console.WriteLine("The pig says: wee wee"); } } class Program { static void Main(string[] args) { Pig myPig = new Pig(); // Create a Pig object myPig.animalSound(); // Call the abstract method myPig.sleep(); // Call the regular method } }
