picture跟随鼠标横向移动

Question

我在窗体上放了个pictureBox1。里面载入一张图片，然后我让他跟随鼠标横向移动，代码我是这样写的
  private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
        {            this.pictureBox1.Location = new Point(this.pictureBox1.Location.X +e.X, this.pictureBox1.Location.Y);        }我是了，鼠标没指到pictureBox1的中间部分呀？我想让鼠标指到pictureBox1的中间，因为pictureBox1的宽度是20，高度是8，所以我想这样写
  private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
        {            this.pictureBox1.Location = new Point(this.pictureBox1.Location.X +e.X+10, this.pictureBox1.Location.Y+4);        }可不对呀？迷糊了，就想实现pictureBox1随着鼠标动，挪动pictureBox1的时候，鼠标在他的正中间，该怎么实现呀？

Answer 1

改成：
pictureBox1.Left += e.X - 10;
            pictureBox1.Top += e.Y - 4;
