In C#, is it possible to mark an overridden virtual method as final so implementers cannot override it? How would I do it?
An example may make it easier to understand:
class A
{
abstract void DoAction();
}
class B : A
{
override void DoAction()
{
// Implements action in a way that it doesn't make
// sense for children to override, e.g. by setting private state
// later operations depend on
}
}
class C: B
{
// This would be a bug
override void DoAction() { }
}
Is there a way to modify B in order to prevent other children C from overriding DoAction, either at compile-time or runtime?
