Equality Operator (AnnRectangle)

C#
Visual Basic
Objective-C
Java
C++

public bool operator ==( 
   AnnRectangle left,
   AnnRectangle right
)

'Declaration
 
Public Operator =( _
   ByVal left As AnnRectangle, _
   ByVal right As AnnRectangle _
) As Boolean

'Usage

public:
bool operator ==( 
   AnnRectangle left,
   AnnRectangle right
)

Parameters

left: The AnnRectangle structure on the left side of the equality operator.
right: The AnnRectangle structure on the right side of the equality operator.

Return Value

This operator returns true if left and right have equal Width and Height values; otherwise false.

If the two rectangles have different units, the comparison will be done after temporarily converting both rectangles to a common unit.

This example creates a rectangle in inches, converts it to pixels then makes sure the 2 rectangles are still equal.
