# Vector.Inequality(Vector, Vector) Operator

## Definition

Compares two vectors for inequality.

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

#### Parameters

vector1
Vector

The first vector to compare.

vector2
Vector

The second vector to compare.

#### Returns

Boolean

`true` if the X and Y components of `vector1` and `vector2` are different; otherwise, `false`.

## Examples

The following example shows how to use this operator (!=) to check whether two Vector structures are not equal.

``````private Boolean overloadedInequalityOperatorExample()
{
Vector vector1 = new Vector(20, 30);
Vector vector2 = new Vector(45, 70);
Boolean areNotEqual;

// Check whether the two Vectors are not equal, using the overloaded
// inequality operator.
// areNotEqual is True.
areNotEqual = (vector1 != vector2);

return areNotEqual;
}
``````
``````Private Function overloadedInequalityOperatorExample() As Boolean
Dim vector1 As New Vector(20, 30)
Dim vector2 As New Vector(45, 70)
Dim areNotEqual As Boolean

' Check whether the two Vectors are not equal, using the overloaded
' inequality operator.
' areNotEqual is True.
areNotEqual = (vector1 <> vector2)

Return areNotEqual

End Function
``````

## Remarks

A vector's X and Y properties are described using Double values. Because the value of a Double can lose precision when arithmetic operations are performed on it, a comparison between two Vector structures that are logically equal might fail.
