    We cannot create the object of abstract class but we can inherit it.

    Abstract classes have the following features: (According to MSDN)

    • An abstract class cannot be instantiated.

    • An abstract class may contain abstract methods and accessors.

    • It is not possible to modify an abstract class with the modifier because the two modifers have opposite meanings. The sealed modifier prevents a class from being inherited and the abstract modifier requires a class to be inherited.

    • A non-abstract class derived from an abstract class must include actual implementations of all inherited abstract methods and accessors.
