Vector.CrossProduct(Vector, Vector) 方法

定义

计算两个向量的叉积。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

参数

vector1
Vector

要计算的第一个向量。The first vector to evaluate.

vector2
Vector

要计算的第二个向量。The second vector to evaluate.

返回

vector1vector2 的叉乘积。The cross product of vector1 and vector2. 可使用下面的公式计算叉乘积:The following formula is used to calculate the cross product: (Vector1.X * Vector2.Y) - (Vector1.Y * Vector2.X)(Vector1.X * Vector2.Y) - (Vector1.Y * Vector2.X)

示例

下面的示例演示如何使用此方法来计算两个Vector结构的叉积。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;

}
