how to use inheritance in asp.net with example

Question

Jignesh Trivedi · Answer

hi, Creating a new class from existing class is called as inheritance.When you derive a class from a base class, the derived class will inherit all members of the base class except constructors, though whether the derived class would be able to access those members would depend upon the accessibility of those members in the base class. Main advantage of inheritance is reusability of the code. public class Animal { public Animal() { Console.WriteLine("Animal constructor"); } public void Greet() { Console.WriteLine("Animal says Hello"); } public void Talk() { Console.WriteLine("Animal talk"); } public virtual void Sing() { Console.WriteLine("Animal song"); } } public class Cow : Animal { public Cow() { Console.WriteLine("Cow constructor"); } public new void Talk() { Console.WriteLine("Dog talk"); } public override void Sing() { Console.WriteLine("Cow song"); } } Animal cow = new Cow(); cow.Talk(); cow.Sing(); cow.Greet(); //Output Animal constructor cow constructor Animal talk cow song Animal says Hello please refer http://www.programcall.com/19/csnet/inheritance-with-an-example-in-csnet.aspx hope this will help you.

We can create a basePage which will inherit from system.web.page and your all pages will inherit only basepage not from system.web.page. You can write some common logic or some common data member which will use in all pages.
