Vector.CrossProduct Method

Calculates the cross product of two vectors.

Namespace:  System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)

public static double CrossProduct(
	Vector vector1,
	Vector vector2


Type: System.Windows.Vector

The first vector to evaluate.

Type: System.Windows.Vector

The second vector to evaluate.

Return Value

Type: System.Double
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)

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;
