Does C# have abstract classes?

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 .

C# Abstract Class Features An abstract class can inherit from a class and one or more interfaces. An abstract class can implement code with non-Abstract methods. An Abstract class can have modifiers for methods, properties etc.6 Nis 2019

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.
