Point.Inequality Operator (Point, Point)

 

Compares two Point structures for inequality.

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

public static bool operator !=(
	Point point1,
	Point point2
)

Parameters

point1
Type: System.Windows.Point

The first point to compare.

point2
Type: System.Windows.Point

The second point to compare.

Return Value

Type: System.Boolean

true if point1 and point2 have different X or Y coordinates; false if point1 and point2 have the same X and Y coordinates.

A point's X and Y coordinates are described using Double values. Because Double values can lose precision when operated on, a comparison between two Point values that are logically equal might fail.

The following example shows how to check whether two Point structures are not equal, using the overloaded (!=) operator.

private Boolean overloadedInequalityOperatorExample()
{
    Point point1 = new Point(20, 30);
    Point point2 = new Point(45, 70);

    // Check whether the two Points are not equal, using the overloaded 
    // inequality operator.
    // areNotEqual is True.
    Boolean areNotEqual = (point1 != point2);

    return areNotEqual;
