# Vector3D.Equality(Vector3D, Vector3D) Betreiber

## Definition

Vergleicht zwei Vector3D-Strukturen auf Gleichheit.Compares two Vector3D structures for equality.

``````public:
static bool operator ==(System::Windows::Media::Media3D::Vector3D vector1, System::Windows::Media::Media3D::Vector3D vector2);``````
``public static bool operator == (System.Windows.Media.Media3D.Vector3D vector1, System.Windows.Media.Media3D.Vector3D vector2);``
``static member ( = ) : System.Windows.Media.Media3D.Vector3D * System.Windows.Media.Media3D.Vector3D -> bool``
``Public Shared Operator == (vector1 As Vector3D, vector2 As Vector3D) As Boolean``

#### Parameter

vector1
Vector3D

Die erste zu vergleichende Vector3D-Struktur.The first Vector3D structure to compare.

vector2
Vector3D

Die zweite zu vergleichende Vector3D-Struktur.The second Vector3D structure to compare.

#### Gibt zurück

Boolean

`true`, wenn die Komponenten X, Y und Z von `vector1` und `vector2` gleich sind, andernfalls `false`.`true` if the X, Y, and Z components of `vector1` and `vector2` are equal; `false` otherwise.

## Beispiele

Das folgende Beispiel zeigt, wie der überladene Gleichheits Operator verwendet wird, um zu prüfen, ob zwei- Vector3D Strukturen gleich sind.The following example shows how to use the overloaded equality operator to check if two Vector3D structures are equal.

``````// Checks if two Vector3D structures are equal using the overloaded equality operator.

Vector3D vector1 = new Vector3D(20, 30, 40);
Vector3D vector2 = new Vector3D(45, 70, 80);
Boolean areEqual;

areEqual = (vector1 == vector2);
// areEqual is False
``````
``````' Checks if two Vector3D structures are equal using the overloaded equality operator.

Dim vector1 As New Vector3D(20, 30, 40)
Dim vector2 As New Vector3D(45, 70, 80)
Dim areEqual As Boolean

areEqual = (vector1 = vector2)
' areEqual is False
``````

## Hinweise

Zwei Vector3D-Strukturen sind gleich, wenn die Werte ihrer Eigenschaften X, Y und Z gleich sind.Two Vector3D structures are equal if the values of their X, Y, and Z properties are the same.

Vector3D Werte werden mithilfe von- Double Werten beschrieben.Vector3D values are described using Double values. Da der Wert von bei der Ausführung die Double Genauigkeit verlieren kann, kann es vorkommen, dass ein Vergleich zwischen zwei Vector3D Werten, die logisch gleich sind, fehlschlägt.Because the value of a Double can lose precision when operated upon, a comparison between two Vector3D values that are logically equal might fail.
