Point.Equality(Point, Point) Point.Equality(Point, Point) Point.Equality(Point, Point) Point.Equality(Point, Point) Operator

Definition

Compares two Point structures for equality.

public:
 static bool operator ==(System::Windows::Point point1, System::Windows::Point point2);
public static bool operator == (System.Windows.Point point1, System.Windows.Point point2);
static member ( = ) : System.Windows.Point * System.Windows.Point -> bool
Public Shared Operator == (point1 As Point, point2 As Point) As Boolean

Parameters

point1
Point Point Point Point

The first Point structure to compare.

point2
Point Point Point Point

The second Point structure to compare.

Returns

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

Examples

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

private Boolean overloadedEqualityOperatorExample()
{
    Point point1 = new Point(10, 5);
    Point point2 = new Point(15, 40);

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

    return areEqual;

}
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

Remarks

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.
