範例

// Calculates the cross product of two Vector3D structures 
// using the static CrossProduct method.  
// Returns a Double.	

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

crossProduct = Vector3D.CrossProduct(vector1,vector2);
// crossProduct is equal to (-400, 200, 50)

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