Point.Subtract 方法

定义

命名空间:

System.Windows

程序集:

WindowsBase.dll

从指定的 Point 中减去指定的 Vector 或 Point。

重载

Subtract(Point, Point)	从指定的 Point 中减去另一个指定的 Point 并将差作为 Vector 返回。
Subtract(Point, Vector)	从指定的 Vector 减去指定的 Point 并返回所得的 Point。

Subtract(Point, Point)

从指定的 Point 中减去另一个指定的 Point 并将差作为 Vector 返回。

public:
 static System::Windows::Vector Subtract(System::Windows::Point point1, System::Windows::Point point2);

public static System.Windows.Vector Subtract (System.Windows.Point point1, System.Windows.Point point2);

static member Subtract : System.Windows.Point * System.Windows.Point -> System.Windows.Vector

Public Shared Function Subtract (point1 As Point, point2 As Point) As Vector

参数

point1

Point

要从中减去 point2 的点。

point2

Point

要从 point1 中减去的点。

返回

Vector

point1 和 point2 之间的差值。

示例

下面的示例演示如何使用静态Subtract方法从另一个Point方法中减去 aPoint。

private Vector subtractExample2()
{

    Point point1 = new Point(10, 5);
    Point point2 = new Point(15, 40);

    // Subtracts a Point from a Point using the static Subtract method
    // and returns the difference as a Vector.
    // vectorResult is equal to (-5, -35)
    Vector vectorResult = Point.Subtract(point1, point2);

    return vectorResult;
}

Private Function subtractExample2() As Vector

    Dim point1 As New Point(10, 5)
    Dim point2 As New Point(15, 40)

    ' Subtracts a Point from a Point using the static Subtract method
    ' and returns the difference as a Vector.
    ' vectorResult is equal to (-5, -35)
    Dim vectorResult As Vector = Point.Subtract(point1, point2)

    Return vectorResult

End Function

Subtract(Point, Vector)

从指定的 Vector 减去指定的 Point 并返回所得的 Point。

public:
 static System::Windows::Point Subtract(System::Windows::Point point, System::Windows::Vector vector);

public static System.Windows.Point Subtract (System.Windows.Point point, System.Windows.Vector vector);

static member Subtract : System.Windows.Point * System.Windows.Vector -> System.Windows.Point

Public Shared Function Subtract (point As Point, vector As Vector) As Point

参数

point

Point

要从中减去 vector 的点。

vector

Vector

要从 vector 中减去的 point。

返回

Point

point 和 vector 之间的差值。

示例

以下示例演示如何使用静态方法从中减去 a Vector Point。Subtract

       private Point subtractExample1()
       {

           Point point1 = new Point(10, 5);
           Vector vector1 = new Vector(20, 30);

           // Subtracts a Vector from a Point using the static Subtract method
           // and returns the difference as a Point.
           // pointResult is equal to (-10, -25).
           Point pointResult = Point.Subtract(point1, vector1);

           return pointResult;
       }

Private Function subtractExample1() As Point

    Dim point1 As New Point(10, 5)
    Dim vector1 As New Vector(20, 30)

    ' Subtracts a Vector from a Point using the static Subtract method
    ' and returns the difference as a Point.
    ' pointResult is equal to (-10, -25).
    Dim pointResult As Point = Point.Subtract(point1, vector1)

    Return pointResult

End Function
