上代码：

            //图片类型            Response.ContentType = "image/jpeg";            //元图路径            string filePath = Server.MapPath("ImgUpload/" + "9d82d158ccbf6c81db35544dbe3eb13533fa4010.jpg");            //水印内容            string addText = "localhost";            System.Drawing.Image image = System.Drawing.Image.FromFile(filePath);            Bitmap bitmap = new Bitmap(image.Width, image.Height);            System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(bitmap);            g.DrawImage(image, 0, 0, image.Width, image.Height);                        //字体            System.Drawing.Font f = new System.Drawing.Font("Arial Black", 30.0f, System.Drawing.FontStyle.Bold);                        //笔刷色值            System.Drawing.Brush b = new System.Drawing.SolidBrush(System.Drawing.Color.Green);            //将原图画在位图上            g.DrawImage(image, new Point(0, 0));            //将水印加在位图上            g.DrawString(addText, f, b, new System.Drawing.PointF(50,50));            //将位图输入到流            bitmap.Save(Response.OutputStream, ImageFormat.Jpeg);            g.Dispose();            image.Dispose();            bitmap.Dispose();
