Hands-On Design Patterns with C# and .NET Core

Inheritance polymorphism

Inheritance polymorphism allows for functionality to be determined at runtime in a similar way to an interface but applies to class inheritance. In our example, a pet can be fed, so we can define this as having a new Feed(IPetFood) method, which uses the interface that was defined previously:

public virtual void Feed(IPetFood food){    Eat(food);}protected void Eat(IPetFood food){    _hunger -= food.Energy;}
