(1)The use of virtual keyword is to enable or to allow a class to be overridden in the derived class.
(2)The use of sealed keyword is to prevent the class from overridden i.e. you can’t inherit sealed classes.
(3)The use of override keyword is to override the virtual method in the derived class.
(4)The use of abstract keyword is to modify the class, method, and property declaration. You cannot directly make calls to an abstract method and you cannot instantiate an abstract class. | |
