示例代码：

Bitmap bmp = new Bitmap("image file path");
            Graphics g = Graphics.FromImage(bmp);
            String str = DateTime.Now.ToString("yyyy-MM-dd HH:mm");
            Font font = new Font("宋体", 8);
            SolidBrush sbrush = new SolidBrush(Color.Black);
            g.DrawString(str, font, sbrush, new PointF(10, 10));
            MemoryStream ms = new MemoryStream();
            bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
