multiple inheritance in c#.net - abstract classes

Question

One quick question.

I understand that multiple inheritance is not supported in c#.net. But you can still achieve the functionality by implementing multiple interfaces. Now my question is Can a child class inherit from two or more classes as long as they are abstract?

Answer 1

In short, no. Multiple interface inheritance implementation is possible, but not multiple class inheritance (abstract or not).

Answer 2

You can't inherit from multiple classes, period. No matter if abstract or not. Read about extension methods, that may help you a bit: if your classes implement an interface, you can attach common functionality to them without inheritance and copy-paste.

Answer 3

No you can only inherit from one class whether it is abstract or concrete.

Here is link to a question that has quite a detailed discussion of abstract vs base classes
