Inheriting from 2 Interfaces

C.E.O. Gargantua

Is it possible for a class to inherit from two interfaces?

When I try to add a second interface, and compile, the error is:
type in interface list is not an interface
related to the second interface.

If I remove the first interface, and compile with just the second, it
succeeds.

It is possible to inherit from (zero or one base class) + (zero to many
interfaces).

Therefore, if the second item in your interface list is a base class, it
won't compile.

Could this be the problem?

If not, could you post some code to demonstrate the problem?

The God's Awful Truth

Ok, yes that was it.

I was using two interfaces.

I assigned each to one of two abstract classes.

Then I tried to derive a class from both class and the interfaces.

What I did is keep the two interfaces, and derive the abstract class
from them. Then I derive a set of classes from the one abstract class.

Thanks Nick!
