Vulpes · Answer

In C# any class (other than a static class) can act as a base class provided it is not sealed. So: class A { // this can be a base class } static class B { // this can't be a base class because its a static class } sealed class C { // this can't be a base class because it's sealed } class D : A { // inherits from A }
