Does C# support multiple inheritance?

Question

A colleague and I are having a bit of an argument over multiple inheritance. I'm saying it's not supported and he's saying it is. So, I thought that I'd ask the brainy bunch on the net.

Answer 1

Sorry, you cannot inherit from multiple classes. You may use interfaces or a combination of one class and interface(s), where interface(s) should follow the class name in the signature.

interface A { } interface B { } class Base { } class AnotherClass { } 

Possible ways to inherit:

class SomeClass : A, B { } // from multiple Interface(s) class SomeClass : Base, B { } // from one Class and Interface(s) 

This is not legal:

class SomeClass : Base, AnotherClass { } 

Answer 2

Nope, use interfaces instead! ^.^
