# Vector.CrossProduct(Vector, Vector)Vector.CrossProduct(Vector, Vector)Vector.CrossProduct(Vector, Vector)Vector.CrossProduct(Vector, Vector) Method

## Definition

Calculates the cross product of two vectors.

``````public:
static double CrossProduct(System::Windows::Vector vector1, System::Windows::Vector vector2);``````
``public static double CrossProduct (System.Windows.Vector vector1, System.Windows.Vector vector2);``
``static member CrossProduct : System.Windows.Vector * System.Windows.Vector -> double``
``Public Shared Function CrossProduct (vector1 As Vector, vector2 As Vector) As Double``

#### Parameters

vector1
Vector Vector Vector Vector

The first vector to evaluate.

vector2
Vector Vector Vector Vector

The second vector to evaluate.

#### Returns

The cross product of `vector1` and `vector2`. The following formula is used to calculate the cross product:

`(Vector1.X * Vector2.Y) - (Vector1.Y * Vector2.X)`

## Examples

The following example shows how to use this method to calculate the cross product of two Vector structures.

``````private Double crossProductExample()
{
Vector vector1 = new Vector(20, 30);
Vector vector2 = new Vector(45, 70);
Double crossProduct;

// crossProduct is equal to 50
crossProduct = Vector.CrossProduct(vector1, vector2);

return crossProduct;

}
