How can implement Dynamic Polymorphism in c# ? Dynamic polymorphism is implemented by abstract classes and virtual functions. using System; namespace PolymorphismApplication { class Shape { protected int width, height; public Shape( int a=0, int b=0) { width = a; height = b; } public virtual int area() { Console.WriteLine("Parent class area :"); return 0; } } class Rectangle: Shape { public Rectangle( int a=0, int b=0): base(a, b) { } public override int area () { Console.WriteLine("Rectangle class area :"); return (width * height); } } class Triangle: Shape { public Triangle(int a = 0, int b = 0): base(a, b) { } public override int area() { Console.WriteLine("Triangle class area :"); return (width * height / 2); } } class Caller { public void CallArea(Shape sh) { int a; a = sh.area(); Console.WriteLine("Area: {0}", a); } } class Tester { static void Main(string[] args) { Caller c = new Caller(); Rectangle r = new Rectangle(10, 7); Triangle t = new Triangle(10, 5); c.CallArea(r); c.CallArea(t); Console.ReadKey(); } } }
