示例1: CType

Private Sub InkCanvas_PreviewMouseDown(ByVal sender As Object, _
                               ByVal e As MouseButtonEventArgs)

    Dim ic As InkCanvas = CType(sender, InkCanvas)

    Dim pt As Point = e.GetPosition(ic)

    ' If the user is moving selected strokes, prepare the strokes to be
    ' moved to another InkCanvas.
    If ic.HitTestSelection(pt) = InkCanvasSelectionHitResult.Selection Then

        Dim selectedStrokes As StrokeCollection = _
                               ic.GetSelectedStrokes()

        Dim strokesToMove As StrokeCollection = _
                             selectedStrokes.Clone()

        ' Remove the offset of the selected strokes so they
        ' are positioned when the strokes are dropped.
        Dim inkBounds As Rect = strokesToMove.GetBounds()
        TranslateStrokes(strokesToMove, -inkBounds.X, -inkBounds.Y)

        ' Perform drag and drop.
        Dim ms As New MemoryStream()
        strokesToMove.Save(ms)

        Dim dataObject As New DataObject _
            (StrokeCollection.InkSerializedFormat, ms)

        Dim effects As DragDropEffects = _
            DragDrop.DoDragDrop(ic, dataObject, DragDropEffects.Move)

        If (effects And DragDropEffects.Move) = DragDropEffects.Move Then

            ' Remove the selected strokes from the current InkCanvas.
            ic.Strokes.Remove(selectedStrokes)
