The purpose of an abstract class (often referred to as an ABC) is to provide an appropriate base class from which other classes can inherit . Abstract classes cannot be used to instantiate objects and serves only as an interface. Attempting to instantiate an object of an abstract class causes a compilation error.
Read moreIs abstract class better than interface in C#?
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 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.
