Does C# have abstract classes?

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.

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.

An abstract class cannot be instantiated. The purpose of an abstract class is to provide a common definition of a base class that multiple derived classes can share .
