.net 将接口获取到的图片字节转为图片并存到本地

 byte[] base = GetTDSFileService.GetAccessoriesByName(path);
                            if (base != null && base.Length > 0)
                            {
                                MemoryStream memStream = new MemoryStream(base);
                                System.Drawing.Image img = System.Drawing.Image.FromStream(memStream);
                                Random rad = new Random();
                                int values = rad.Next(1000, 10000);//用rad生成大于等于1000，小于等于9999的随机数；
                                string suijishu = values.ToString(); //转化为字符串；
                                string fileName = DateTime.Now.ToString("yyyyMMdd") + suijishu + ".jpg";
                                img.Save(Server.MapPath("../pages/UpFile/") + fileName);
                                imgPath += "../UpFile/" + fileName + ",";
                            }
