.NET Framework Class Library
Point..::.Inequality Operator

Compares two Point structures for inequality.

Namespace:  System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)
Visual Basic
Public Shared Operator <> ( _
    point1 As Point, _
    point2 As Point _
) As Boolean
C#
public static bool operator !=(
    Point point1,
    Point point2
)
Visual C++
public:
static bool operator !=(
    Point point1, 
    Point point2
)
F#
static let inline (<>)
        point1:Point * 
        point2:Point  : bool

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.

Visual Basic
        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
C#
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;

}
