# Point4D.Inequality(Point4D, Point4D) Operator

## Definition

Vergleicht zwei Point4D-Strukturen auf Ungleichheit.Compares two Point4D structures for inequality.

``````public:
static bool operator !=(System::Windows::Media::Media3D::Point4D point1, System::Windows::Media::Media3D::Point4D point2);``````
``public static bool operator != (System.Windows.Media.Media3D.Point4D point1, System.Windows.Media.Media3D.Point4D point2);``
``static member op_Inequality : System.Windows.Media.Media3D.Point4D * System.Windows.Media.Media3D.Point4D -> bool``
``Public Shared Operator != (point1 As Point4D, point2 As Point4D) As Boolean``

#### Parameter

point1
Point4D

Die erste zu vergleichende Point4D-Struktur.The first Point4D structure to compare.

point2
Point4D

Die zweite zu vergleichende Point4D-Struktur.The second Point4D structure to compare.

#### Gibt zurück

`true`, wenn die X-, Y-, Z- und die W-Koordinate von `point4D1` und `point4D2` ungleich sind, andernfalls `false`.`true` if the X, Y, Z, and W coordinates of `point4D1` and `point4D2` are different; otherwise, `false`.

## Beispiele

Das folgende Beispiel zeigt, wie der überladene Ungleichheits Operator verwendet wird Point4D , um zu überprüfen, ob zwei-Strukturen ungleich sind.The following example shows how to use the overloaded inequality operator to check whether two Point4D structures are not equal.

``````// Checks if two Point4Ds are not equal using the overloaded inequality operator.

Point4D point1 = new Point4D(10, 5, 1, 4);
Point4D point2 = new Point4D(15, 40, 60, 75);
Boolean areNotEqual;

areNotEqual = (point1 != point2);
// areNotEqual is True

// Displaying Results
syntaxString = "areNotEqual = (point1 != point2);";
resultType = "Boolean";
operationString = "Checking if two 3D points are not equal";
ShowResults(areNotEqual.ToString(), syntaxString, resultType, operationString);
``````
``````' Checks if two Point4Ds are not equal using the overloaded inequality operator.

Dim point1 As New Point4D(10, 5, 1, 4)
Dim point2 As New Point4D(15, 40, 60, 75)
Dim areNotEqual As Boolean

areNotEqual = (point1 <> point2)
' areNotEqual is True

' Displaying Results
syntaxString = "areNotEqual = (point1 != point2)"
resultType = "Boolean"
operationString = "Checking if two 3D points are not equal"
ShowResults(areNotEqual.ToString(), syntaxString, resultType, operationString)
``````

## Hinweise

Zwei Point4D -Strukturen sind nicht gleich, wenn die Werte XIhrer YEigenschaften Z,, W und unterschiedlich sind.Two Point4D structures are not equal if the values of their X, Y, Z, and W properties are different.

Da bei Double der Ausführung arithmetischer Operationen bei einem Wert die Genauigkeit verloren gehen kann, kann es Point4D vorkommen, dass ein Vergleich zwischen zwei Werten, die logisch gleich sind, fehlschlägt.Because a Double value can lose precision when arithmetic operations are performed on them, a comparison between two Point4D values that are logically equal might fail.
