Explicit(Point to Vector)
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
參數
- point
- Point
要轉換的點。
傳回
向量,其 X 值等於這個點的 X 值且 Y 值等於這個點的 Y 值。
範例
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
適用於
Explicit(Point to Size)
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
參數
- point
- Point
要轉換的點。
傳回
Size 結構,其 Width 等於這個點的 X 值且 Height 等於這個點的 Y 值。
範例
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
備註
Size因為 結構不能是負數,所以會使用點和 Y 屬性的 X 絕對值。
