)

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

'Usage

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

This operator type is not supported by WinRT JavaScript

public:
bool operator ==(

   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.
