如何在另一个pictureBox中制作Drag＆amp; Drop图片框

Question

private void CreateControls()
    {
        if (pictures[0] != null)
            DisposeControls();

        for (var i = 0; i < 52; i++)
        {
            var newPictureBox = new PictureBox();
            newPictureBox.Width = 75;
            newPictureBox.Height = 100;
            //newPictureBox.BorderStyle = BorderStyle.Fixed3D;
            pictures[i] = SizeImage(newPictureBox, i + 1);

        }
    }

    private void DisplayControls()
    {
        for (var i = 51; i >= 0; i--)
        {
            var picture = pictures[i];
            picture.Left = (i*15) + 15;
            picture.Top = 50;
            this.Controls.Add(picture);
        }
    }

所以，我有这个，但我所做的并不奏效。 更准确地说，我有2个图片框，我需要将PictureBox拖到PictureBox1 ... 我试过了：

//picture.MouseMove += (ss, ee) =>
            //{
            //    if (ee.Button == MouseButtons.Left)
            //    {
            //        //create a temporary point
            //        Point temp = MousePosition;
            //        Point res = new Point(firstPoint.X - temp.X, firstPoint.Y - temp.Y);
            //        //apply value to object
            //        picture.Location = new Point(picture.Location.X, picture.Location.Y);
            //        //update first point
            //        firstPoint = temp;
            //    }
            //};

但仍然无效.. 我怎么能让它发挥作用？
