Besides allocating memory for a new reference object, C#
uses the new keyword to hide the implementation of a method or property
from the member that has the same name in a base class. Here is an example of
using it:
|
using System;
public class Square
{
private double _side;
public double Side
{
get { return (_side < 0) ? 0.00 : _side; }
set { _side = value; }
}
public double Area
{
get { return _side * _side; }
}
}
public class Cube : Square
{
new public double Area
{
get { return this.Side * this.Side * this.Side; }
}
}
public class Exercise
{
static void ShowCube(Cube faces)
{
Console.WriteLine("Characteristics of the cube");
Console.WriteLine("Side: {0}", faces.Side);
Console.WriteLine("Area: {0}", faces.Area);
}
static void Main()
{
Cube SixFaces = new Cube();
SixFaces.Side = 24.55;
ShowCube(SixFaces);
}
}
