像狗皮膏药一样的图片拖拉操作

今天因为要用到图片拖拉操作，所以简单的看了下，做了一个简单的demo，先来张效果图: 像狗皮膏药一样的图片拖拉操作

code is simple:

Code
public partial class 图片拖放 : Form
    {
        public 图片拖放()
        {
            InitializeComponent();
        }
        PictureBox pb = null;

        private void 图片拖放_Load(object sender, EventArgs e)
        {
            panel1.AllowDrop = true;
        }

        private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
        {
            this.pictureBox1.DoDragDrop(this.pictureBox1.Image, DragDropEffects.Copy);
        }

        private void panel1_DragEnter(object sender, DragEventArgs e)
        {
            e.Effect = DragDropEffects.Copy;
        }

        private void panel1_DragDrop(object sender, DragEventArgs e)
        {
            pb = new PictureBox();
            pb.Image = (Image)e.Data.GetData(DataFormats.Bitmap);
            pb.Size = new Size(26, 24);
            pb.Location = new Point(e.X - 105 - Location.X, e.Y - 30 - Location.Y);

            this.panel1.Controls.Add(pb);
        }
    }
