我从我的代码中得到了一个eroor,我无法追踪问题/错误.这是我的代码位...

private void DoArrange()
    {
        Point center = new Point((this.Width - ItemSize) / 2, (this.Height - ItemSize) / 2);
        double radiusX = center.X;
        double radiusY = center.Y;
        double scale = ScalePerspective;

        for (int i = 0; i < Children.Count; i++)
        {
            UIElement item = Children[i];
            double radians = (double)item.GetValue(CarouselPanel.AngleProperty);

            Point p = new Point(
                                (Math.Cos(radians) * radiusX) + center.X,
                                (Math.Sin(radians) * radiusY) + center.Y
                               );

            if (item.RenderTransform == null)
            {
                item.RenderTransform = new MatrixTransform();
                item.RenderTransformOrigin = new Point(0.5, 0.5);
            } …
