Base Keyword in C#
In this article I will explain about base keyword in C#.
Introduction
The concept of base keyword is very simple in c#. The base keyword is used when we want to access members and functionalities of the base class, from within a derived class. In the following example, both the base class, Owner, and the derived class, Employee, have a method named info. By using the base keyword, it is possible to call the info method on the base class, from within the derived class.
Example
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace this_example
{
public class Owner
{
protected string pinname = "78";
protected string name = "rahul";
public virtual void Info()
{
Console.WriteLine("Name: {0}", name);
Console.WriteLine("pinname: {0}", pinname);
}
}
class Employee : Owner
{
public string id = "ABC567";
public override void Info()
{
// Calling the base class GetInfo method:
base.Info();
Console.WriteLine("Employee ID: {0}", id);
}
}
class TestClass
{
public static void Main()
{
Employee E = new Employee();
E.Info();
Console.ReadLine();
}
}
}
The output of following program
