An interface is better than an abstract class when multiple classes need to implement the interface . The member of the interface cannot be static. The only complete member of an abstract class can be static. C# does not support multiple inheritances; interfaces are mainly used to implement the multiple inheritances.
Read moreWhat is a abstract class C++?
An abstract class is a class that is designed to be specifically used as a base class . An abstract class contains at least one pure virtual function. You declare a pure virtual function by using a pure specifier ( = 0 ) in the declaration of a virtual member function in the class declaration.
Read moreWhat is abstract class explain it with an example?
Abstract classes are essential to providing an abstraction to the code to make it reusable and extendable . For example, a Vehicle parent class with Truck and Motorbike inheriting from it is an abstraction that easily allows more vehicles to be added.

Points to Remember
Read moreIs abstract a keyword in C?
abstract (C++/CLI and C++/CX) The abstract keyword declares either: A type can be used as a base type, but the type itself cannot be instantiated . A type member function can be defined only in a derived type.
Read moreWhat is an abstract method C#?
An Abstract method is a method without a body . The implementation of an abstract method is done by a derived class. When the derived class inherits the abstract method from the abstract class, it must override the abstract method. This requirment is enforced at compile time and is also called dynamic polymorphism.

An abstract class is a class that is declared abstract —it may or may not include abstract methods. Abstract classes cannot be instantiated, but they can be subclassed.
