Question

我想直截了当地把我从开始点获得的东西放在一边,但现在,我把直截了当地摆到电影院中间,当时我想把它放在起点的位置上。

private void DragSelectComponent_SelectionEnd(DragSelectEventArgs e)
{
    Output.Text = "Start: " + e.StartPoint.ToString() + "     End: " + e.EndPoint.ToString() + "
(" + e.EventType + ")
";
    Rectangle rectangle = new Rectangle() { Width = e.EndPoint.X - e.StartPoint.X, Height = e.EndPoint.Y - e.StartPoint.Y, Fill = new SolidColorBrush(Colors.Purple) };
    PictureCanvas.Children.Add(rectangle);
}

Answer 1

公正使用:-

 Rectangle rectangle = new Rectangle() { Width = e.EndPoint.X - e.StartPoint.X, Height = e.EndPoint.Y - e.StartPoint.Y, Fill = new SolidColorBrush(Colors.Purple) };
 Canvas.SetLeft(rectangle, e.StartPoint.X);
 Canvas.SetTop(rectangle, e.StartPoint.Y);
 PictureCanvas.Children.Add(rectangle);

Answer 2

您:

rectangle.SetValue(Canvas.LeftProperty, p.X);
rectangle.SetValue(Canvas.TopProperty, p.Y);
