Rules for Inheriting class

Question

Can I set rules for the class inheriting my base class. eg. Person : BaseClass, I want Person to implement iSomeKindOfInterface, if Person does not implement the interface, it is not allowed to inherit from BaseClass.

I know this is posibble in generic base classes where you can do the following

public BaseClass<T>
     where T : iSomeKinfOfInterface

Answer 1

You can implement the interface in your base class and force the inheriting class to supply the implementation:

public interface ISomeInterface
{
    void DoSomething();
}

public abstract class BaseClass : ISomeInterface
{
    public abstract void DoSomething();
}

public class Person : BaseClass
{
    public override void DoSomething()
    {
        ...
    }
}

Answer 2

Declare your class as

abstract BaseClass : ISomeKinfOfInterface
