We can use the base keyword to reference members from parent class.
It is especially useful when referencing the overridden method.
using System;
class Shape{
public virtual int Area{
get{
return 0;
}
}
}
class Rectangle:Shape{
public int width;
public int height;
public override int Area{
get{
Console.WriteLine(base.Area);
return width * height;
}
}
}
class Program
{
static void Main(string[] args)
{
Rectangle r = new Rectangle();
r.width = 4;
r.height = 6;
Console.WriteLine(r.Area);
}
}
The output:
