C# — Polymorphism

Virtual methods

class Animal {
    public virtual void Sound() {
        Console.WriteLine("Some sound");
    }
}

class Dog : Animal {
    public override void Sound() {
        Console.WriteLine("Bark");
    }
}

Runtime polymorphism

Animal myAnimal = new Dog();
myAnimal.Sound();  // Bark
