We can use this class in this senario 1. If we have created some method and we want to modify some methods with new feature and we have to use somewhere then we can use abstract class 2. If we are developing some product type project where we have to keep on adding new features in coming days then we can use abstract class.

Hi Pawan Refer to this post and read it carefully this answers your question: http://www.headspring.com/two-reasons-to-use-abstract-classes-in-c/ Also you may want to Google it. Basically Abstract classes help you improve your code not only through what they can do but also through what they can't. They can hold common features for many classes to inherit without accidentally becoming objects themselves. They can also force you to write unique implementations of a common method preventing human errors of forgetfulness. When you set up a class hierarchy seriously consider whether you need a normal class to inherit from or whether an abstract class will do. It may end up making the difference between a solid or buggy program. Mark it as answer if it helps. Cheers!
