The code uses the feature of Operator Overloading in C#. It shows how different operators are overloaded and can be used in a easy manner.

using System;
class Rectangle
{
private int iHeight;
private int iWidth;
public Rectangle()
{
Height=0;
Width=0;
}
public Rectangle(int w,int h)
{
Width=w;
Height=h;
}
public int Width
{
get
{
return iWidth;
}
set
{
iWidth=
value;
}
}
public int Height
{
get
{
return iHeight;
}
set
{
iHeight=
value;
}
}
public int Area
{
get
{
return Height*Width;
}
}
public static bool operator==(Rectangle a,Rectangle b)
{
return ((a.Height==b.Height)&&(a.Width==b.Width));
}
public static bool operator!=(Rectangle a,Rectangle b)
{
return !(a==b);
}
/* Overloding > */
public static bool operator>(Rectangle a,Rectangle b)
{
return a.Area>b.Area;
}
public static bool operator<(Rectangle a,Rectangle b)
{

}
public static bool operator>=(Rectangle a,Rectangle b)
{
return (a>b)||(a==b);
}
public static bool operator<=(Rectangle a,Rectangle b)
{
return (a<b)||(a==b);
}
public override String ToString()
{
return "Height=" + Height + ",Width=" + Width;
}
public static void Main()
{
Rectangle objRect1 =
new Rectangle();
