Point.Equality Operator (Point, Point)

 

Compares two Point structures for equality.

Namespace:   System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)

Public Shared Operator = (
	point1 As Point,
	point2 As Point
) As Boolean

Parameters

point1
Type: System.Windows.Point

The first Point structure to compare.

point2
Type: System.Windows.Point

The second Point structure to compare.

Return Value

Type: System.Boolean

true if both the X and Y coordinates of point1 and point2 are equal; otherwise, false.

A point's coordinates are described using Double values. Because the value of Double can lose precision when arithmetic operations are performed on them, a comparison between two Point values that are logically equal might fail.

The following example shows how to check if two Point structures are equal using the overloaded (==) operator.

Private Function overloadedEqualityOperatorExample() As Boolean
	Dim point1 As New Point(10, 5)
	Dim point2 As New Point(15, 40)

	' Check if two Points are equal using the overloaded equality operator.
	' areEqual is False.
	Dim areEqual As Boolean = (point1 = point2)

	Return areEqual

End Function
