Hi Example : using System; namespace Polymorphism { class A { public virtual void Test() { Console.WriteLine( A::Test() ); } } class B : A { public override void Test() { Console.WriteLine( B::Test() ); } } class C : B { public override void Test() { Console.WriteLine( C::Test() ); } } class Program { static void Main( string [] args) { A a = new A(); B b = new B(); C c = new C(); a.Test(); // output --> A::Test() b.Test(); // output --> B::Test() c.Test(); // output --> C::Test() a = new B(); a.Test(); // output --> B::Test() b = new C(); b.Test(); // output --> C::Test() Console.ReadKey(); } } } Refer the following article: http://www.c-sharpcorner.com/UploadFile/3d39b4/virtual-method-in-C-Sharp/ http://www.dotnet-tricks.com/Tutorial/csharp/U33Y020413-Understanding-virtual-override-and-new-keyword-in-C
