Vector.AngleBetween(Vector, Vector) 方法

定義

命名空間:
System.Windows
組件:
WindowsBase.dll

取兩個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

第一個要評估的向量。

vector2
Vector

第二個評估向量。

傳回

Double

與 之間的vector1vector2角度（度數）。

範例

以下範例說明如何使用此方法取得兩個 Vector 結構間的角度。

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;
}
