Give an example of polymorphism in C#.?

abstract class Shape { public abstract void Draw(); }

class Circle : Shape { public override void Draw() =>

Console.WriteLine("Drawing Circle"); }

class Rectangle : Shape { public override void Draw() =>

Console.WriteLine("Drawing Rectangle"); }

Shape s1 = new Circle();
Shape s2 = new Rectangle();

s1.Draw(); // Circle's Draw

s2.Draw(); // Rectangle's Draw
