示例1: InkCanvas_PreviewMouseDown
void InkCanvas_PreviewMouseDown(object sender, MouseEventArgs e)
{
InkCanvas ic = (InkCanvas)sender;
Point pt = 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)
{
StrokeCollection selectedStrokes = ic.GetSelectedStrokes();
StrokeCollection strokesToMove = selectedStrokes.Clone();
// Remove the offset of the selected strokes so they
// are positioned when the strokes are dropped.
Rect inkBounds = strokesToMove.GetBounds();
TranslateStrokes(strokesToMove, -inkBounds.X, -inkBounds.Y);
// Perform drag and drop.
MemoryStream ms = new MemoryStream();
strokesToMove.Save(ms);
DataObject dataObject = new DataObject(
StrokeCollection.InkSerializedFormat, ms);
DragDropEffects effects =
DragDrop.DoDragDrop(ic, dataObject,

if ((effects & DragDropEffects.Move) ==
DragDropEffects.Move)
{
// Remove the selected strokes
// from the current InkCanvas.
