Vector.AngleBetween(Vector, Vector) 方法

定義

命名空間:

System.Windows

組件:

WindowsBase.dll

擷取兩個所指定向量之間的角度 (以度數表示)。

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

參數

vector1

Vector

要評估的第一個向量。

vector2

Vector

要評估的第二個向量。

傳回

Double

vector1 與 vector2 之間的角度 (以度數為單位)。

範例

下列範例示範如何使用這個方法來取得兩 Vector 個結構之間的角度。

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;
}
