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

Box Box2 = new Box (); / / declare Box2 with type Box

Box Box3 = new Box (); / / declare Box3 with type Box

Box Box4 = new 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

Volume = Box1.getVolume ()

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")

If (Box1
