Vector.AngleBetween(Vector, Vector) 方法

定义

检索两个指定向量之间的角度(用度表示)。Retrieves the angle, expressed in degrees, between the two specified vectors.

public:
 static double AngleBetween(System::Windows::Vector vector1, System::Windows::Vector vector2);
public static double AngleBetween (System.Windows.Vector vector1, System.Windows.Vector vector2);
static member AngleBetween : System.Windows.Vector * System.Windows.Vector -> double
Public Shared Function AngleBetween (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 之间的角度(以度为单位)。The angle, in degrees, between vector1 and vector2.

示例

下面的示例演示如何使用此方法来获取两个Vector结构之间的角度。The following example shows how to use this method to get the angle between two Vector structures.

private Double angleBetweenExample()
{
    Vector vector1 = new Vector(20, 30);
    Vector vector2 = new Vector(45, 70);
    Double angleBetween;

    // angleBetween is approximately equal to 0.9548
    angleBetween = Vector.AngleBetween(vector1, vector2);

    return angleBetween;

}
