c#.net doesn’t support multiple inheritance through classes

Hi Ashok,

C# doesnot support multiple inheritance due to diamond problem.

The Diamond problem is an ambiguity that arises when two classes B and C inherit from Class A and class D inherits from both B and C. If a method in D calls a method defined in A(and does not override the method), and B and C have overridden that method differently, then from which class does it inherit: B or C?
