diff between abstract class vs interface
Basically, an abstract class = interface if it has all abstract functions. But the abstract class can have variables when interface doesn't.
To decide whether you should use abstract class or interface, you have to think about the structure of your application. If you want to push all derived class to have similar behaviors and they are pre-defined, then abstract class is the case, and one more important point is you can inherit only one abstract class while many interfaces can be inherited. Cheers.

Hi,
One more thing .net does not supports multiple inheritence directly but interface is the way to accomplish multiple inheritence....
