Question

Let’s say I have 3 classes:

GrandDad, Dad and Son. Son inherits from Dad, which inherits from GrandDad.

GrandDad has 2 methods:

public virtual void foo();
public virtual void do();

Dad inherits foo(), but overrides do();

public override void do();

If Son wants to modify foo(), is it acceptable to:

make Dad override foo(), but simply call foo.base()? Then Son can override foo(), but Dad’s foo() functionality remains the same?

Or is that a hacky way?

Answer 1

As long as Dad never defined a foo(), there’s no reason he has to do anything. Son should be able to override foo() from GrandDad.
