Equality Operator (AnnLength)

C#
Visual Basic
Objective-C
Java
C++

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

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

'Usage

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

Parameters

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

Return Value

This operator returns true if left and right have equal lengths; otherwise false.

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

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