heloo.... i want to hide the base class method using new operator. i tried this code.but it was not working.here base class method is calling. plz help me soon. using System; using System.Collections.Generic; using System.Text; namespace ConsoleApplication23 { class Program:user { public new void print() { Console.WriteLine("hello how are you?"); } static void Main(string[] args) { user u = new Program(); u.print(); Console.ReadLine(); } } class user { public void print() { Console.WriteLine("hellohello"); } } } sravani.p

Hey, the 'new' keyword is to explicitly hide the base class members But, if you want to use it, you have to call the method from the derived class. In this case you surely need to create a reference of the derived class other than a original base class reference. Since you have already created the Program object to a user reference, all you need to do is to perform a cast: (Program)u.print(); regards

It's working just fine. You have a reference to
user, so when you use theprintmethod, the method in theuserclass is used. If you want the method in the Program class to be used when you have a Program instance references by a reference to user, you have to use a virtual method instead of using the new modifier.--- single minded; short sighted; long gone;
