Point.Explicit 运算符

定义

命名空间:

System.Windows

程序集:

WindowsBase.dll

将 Point 转换为 Size 或 Vector。

重载

Explicit(Point to Vector)	创建一个 Vector 结构，该结构的 X 值等于该点的 X 值，且 Y 值等于该点的 Y 值。
Explicit(Point to Size)	创建一个 Size 结构，该结构的 Width 等于此点的 X 值，且 Height 等于此点的 Y 值。

Explicit(Point to Vector)

创建一个 Vector 结构，该结构的 X 值等于该点的 X 值，且 Y 值等于该点的 Y 值。

public:
 static explicit operator System::Windows::Vector(System::Windows::Point point);

public static explicit operator System.Windows.Vector (System.Windows.Point point);

static member op_Explicit : System.Windows.Point -> System.Windows.Vector

Public Shared Narrowing Operator CType (point As Point) As Vector

参数

point

Point

要变换的点。

返回

Vector

一个向量，它的 X 值等于该点的 X 值，且 Y 值等于该点的 Y 值。

示例

下面的示例演示如何显式转换为 Point a Vector.

private Vector overloadedExplicitOperatorVectorExample()
{

    Point point1 = new Point(10, 5);

    // Explicitly converts a Point structure into a Vector structure.
    // returnVector is equal to (10,5).
    Vector returnVector = (Vector)point1;

    return returnVector;
}

Private Function overloadedExplicitOperatorVectorExample() As Vector

    Dim point1 As New Point(10, 5)

    ' Explicitly converts a Point structure into a Vector structure.
    ' returnVector is equal to (10,5).
    Dim returnVector As Vector = CType(point1, Vector)

    Return returnVector

End Function

Explicit(Point to Size)

创建一个 Size 结构，该结构的 Width 等于此点的 X 值，且 Height 等于此点的 Y 值。

public:
 static explicit operator System::Windows::Size(System::Windows::Point point);

public static explicit operator System.Windows.Size (System.Windows.Point point);

static member op_Explicit : System.Windows.Point -> System.Windows.Size

Public Shared Narrowing Operator CType (point As Point) As Size

参数

point

Point

要变换的点。

返回

Size

一个 Size 结构，它的 Width 等于此点的 X 值，且 Height 等于此点的 Y 值。

示例

下面的示例演示如何显式转换为 Point a Size.

private Size overloadedExplicitOperatorSizeExample()
{

    Point point1 = new Point(10, 5);

    // Explicitly converts a Point structure into a Size structure.
    // returnSize has a width of 10 and a height of 5  
    Size returnSize = (Size)point1;

    return returnSize;
}

Private Function overloadedExplicitOperatorSizeExample() As Size

    Dim point1 As New Point(10, 5)

    ' Explicitly converts a Point structure into a Size structure.
    ' returnSize has a width of 10 and a height of 5  
    Dim returnSize As Size = CType(point1, Size)

    Return returnSize

End Function

注解

Size由于结构不能为负值，因此使用了点的X绝对值和Y属性。
