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
