inheritance - C#: How do I call a static method of a base class from a static method of a derived class?

In C#, I have base class Product and derived class Widget.

Product contains a static method MyMethod().

I want to call static method Product.MyMethod() from static method Widget.MyMethod().

I can't use the base keyword, because that only works with instance methods.

I can call Product.MyMethod() explicitly, but if I later change Widget to derive from another class, I have to revise the method.

Is there some syntax in C# similar to base that allows me to call a static method from a base class from a static method of a derived class?

static methods are basically a method to fallback from object oriented concepts. As a consequence, they are not very flexible in inheritance hierarchies and it's not possible to do such a thing directly.

The closest thing I can think of is a using directive.

using mybaseclass = Namespace.BaseClass;

class MyClass : mybaseclass {

  static void MyMethod() {  mybaseclass.BaseStaticMethod();  }

}
