# Vector3D.Inequality(Vector3D, Vector3D) Operator

## Definition

Compares two Vector3D structures for inequality.

``````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 op_Inequality : System.Windows.Media.Media3D.Vector3D * System.Windows.Media.Media3D.Vector3D -> bool``
``Public Shared Operator != (vector1 As Vector3D, vector2 As Vector3D) As Boolean``

#### Parameters

vector1
Vector3D

The first Vector3D structure to compare.

vector2
Vector3D

The second Vector3D structure to compare.

#### Returns

`true` if the X, Y, and Z components of `vector3D1` and `vector3D2` are different; `false` otherwise.

## Examples

The following example shows how to use the overloaded inequality operator to check if two Vector3D structures are not equal.

``````// Checks if two Vector3D structures are not equal using the overloaded inequality operator.

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

areNotEqual = (vector1 != vector2);
// areNotEqual is True
``````
``````' Checks if two Vector3D structures are not equal using the overloaded inequality operator.

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

areNotEqual = (vector1 <> vector2)
' areNotEqual is True
``````

## Remarks

Two Vector3D structures are not equal if the values of their X, Y, and Z properties are different.

Vector3D values are described using Double values. Because the value of a Double can lose precision when operated upon, a comparison between two Vector3D values that are logically equal might fail.
