强制子对象实现静态方法

Question

I want to allow all my child objects to implement static method. For example:

public abstract class A {}
public class B : A {}
public class C : A {}

I want B and C to have DoSomething() static method, where in A there will be default implementation of DoSomething().

What is the bes practice to do so?

Answer 1

You can't do so. You wouldn't be able to call the static method polymorphically anyway. Basically, static members and polymorphism don't work together. Either give up on polymorphism, or create a parallel type hierarchy where those are instance methods.
