Point.Inequality(Point, Point) Operator

Definition

Namespace:

System.Windows

Assembly:

WindowsBase.dll

Compares two Point structures for inequality.

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 op_Inequality : System.Windows.Point * System.Windows.Point -> bool

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

Parameters

point1

Point

The first point to compare.

point2

Point

The second point to compare.

Returns

Boolean

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

Examples

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;
}

Private Function overloadedInequalityOperatorExample() As Boolean
    Dim point1 As New Point(20, 30)
    Dim point2 As New Point(45, 70)

    ' Check whether the two Points are not equal, using the overloaded 
    ' inequality operator.
    ' areNotEqual is True.
    Dim areNotEqual As Boolean = (point1 <> point2)

    Return areNotEqual

End Function

Remarks

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.
