解决了 
很简单
       //对图片进行放大缩小操作       
        private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
        {
            //string  width = pictureBox1.Width.ToString();
            if (e.Button == MouseButtons.Left)
            {
                if (pictureBox1.Width < 1360)
                {
                    pictureBox1.Width = Convert.ToInt32(pictureBox1.Width * 1.2);
                    pictureBox1.Height = Convert.ToInt32(pictureBox1.Height * 1.2);
                }
            }
            if (e.Button == MouseButtons.Right)
            {
                if (pictureBox1.Width > 635)
                {
                    pictureBox1.Width = Convert.ToInt32(pictureBox1.Width / 1.2);
                    pictureBox1.Height = Convert.ToInt32(pictureBox1.Height / 1.2);
                }
            }
        }
