The base keyword has two uses: 1. To call a base class constructor from a derived class constructor. 2. To call a base class method which is overridden in the derived class. This simple program illustrates both uses: using System; class Parent { string message; public virtual void MyMethod() { Console.WriteLine(message); } public Parent (string message) { this.message = message; } } class Child : Parent { public override void MyMethod() { Console.WriteLine("Hello from child class"); } public void YourMethod() { base.MyMethod(); } public Child (string message) : base (message) { } } class Test { static void Main() { Child c = new Child("Hello from base class"); c.MyMethod(); c.YourMethod(); Console.ReadKey(); } } The output is: Hello from child class Hello from base class

C# base keyword is used to call the base class constructor and base class field. First the values are received by the derived class constructor and then passed to the base class constructor. See The Code class A { int i; A(int n, int m) { x = n; y = m Console.WriteLine("n="+x+"m="+y); } } class B:A { int i; B(int a, int b):base(a,b)//calling base class constructor and passing value { base.i = a;//passing value to base class field i = b; } public void Show() { Console.WriteLine("Derived class i="+i); Console.WriteLine("Base class i="+base.i); } } class MainClass { static void Main(string args[]) { B b=new B(7,8);//passing value to derive class constructor b.Show(); } } OUTPUT n=7 m= 8 Derived class i=8 Base class i=7
