How to overload more operators in C #
This article introduces the knowledge of "how to overload more operators in C #". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
Example
Using System
Namespace OperatorOvlApplication
{
Class Box
{
Private double length; / / length
Private double breadth; / / width
Private double height; / / height
Public double getVolume ()
{
Return length * breadth * height
}
Public void setLength (double len)
{
Length = len
}
Public void setBreadth (double bre)
{
Breadth = bre
}
Public void setHeight (double hei)
{
Height = hei
}
/ / overload + operator to add two Box objects
Public static Box operator+ (Box b, Box c)
{
Box box = new Box ()
Box.length = b.length + c.length
Box.breadth = b.breadth + c.breadth
Box.height = b.height + c.height
Return box
}
Public static bool operator = (Box lhs, Box rhs)
{
Bool status = false
If (lhs.length = = rhs.length & & lhs.height = = rhs.height
& & lhs.breadth = = rhs.breadth)
{
Status = true
}
Return status
}
Public static bool operator! = (Box lhs, Box rhs)
{
Bool status = false
If (lhs.length! = rhs.length | | lhs.height! = rhs.height
| lhs.breadth! = rhs.breadth) |
{
Status = true
}
Return status
}
Public static bool operator rhs.breadth)
{
Status = true
}
Return status
}
Public static bool operator = rhs.breadth)
{
Status = true
}
Return status
}
Public override string ToString ()
{
Return String.Format ("({0}, {1}, {2})", length, breadth, height)
}
}
Class Tester
{
Static void Main (string [] args)
{
Box Box1 = new Box (); / / declare Box1 with type Box

Double volume = 0; / / Volume
/ / Box1 details
Box1.setLength (6.0)
Box1.setBreadth (7. 0)
Box1.setHeight (5.0)
/ / Box2 details
Box2.setLength (12.0)
Box2.setBreadth (13.0)
Box2.setHeight (10.0)
/ / use overloaded ToString () to display two boxes
Console.WriteLine ("Box1: {0}", Box1.ToString ())
Console.WriteLine ("Box2: {0}", Box2.ToString ())
/ / Volume of Box1

Console.WriteLine ("volume of Box1: {0}", volume)
/ / Volume of Box2
Volume = Box2.getVolume ()
Console.WriteLine ("volume of Box2: {0}", volume)
/ / add two objects together
Box3 = Box1 + Box2
Console.WriteLine ("Box3: {0}", Box3.ToString ())
/ / Volume of Box3
Volume = Box3.getVolume ()
Console.WriteLine ("volume of Box3: {0}", volume)
/ / comparing the boxes
If (Box1 > Box2)
Console.WriteLine ("Box1 is greater than Box2")
Else
Console.WriteLine ("Box1 is not greater than Box2")
If (Box1 = Box2)
Console.WriteLine ("Box1 greater than or equal to Box2")
Else
Console.WriteLine ("Box1 is not greater than or equal to Box2")
