Hi I am a little confused about interfaces.
Can an abstract class inherit an interface, so that interface can be used in conjunction of a class derived from the adstract?
eg A is an interface, B is an abstarcat class, C & D inherit from B but have different proerties.
Can A still be utilised to interface with C and D, if so how will the one method in the interface be passed down through the adstract class and will the derived classes have to overide the method?
