GDI+ 中发生一般性错误

[枫之幻月]

public static string CreateDirectory(string str)
    {
        if (!Directory.Exists(HttpContext.Current.Server.MapPath(str)))//如果不存在就创建str文件夹
        {
            Directory.CreateDirectory(HttpContext.Current.Server.MapPath(str));
        }
        return str;
    }

try
        {
            string base64 = context.Request["base64"].Trim().ToString();　　　　　　//接收前台传过来的参数
            byte[] btsdata = Convert.FromBase64String(base64);
            string ImgName = Guid.NewGuid().ToString("D") + ".jpg";
            string uploadDir = OA_Class.CreateDirectory("~/images/Shipping/" + DateTime.Now.Year + "/") + ImgName;
            using (System.Drawing.Image img = System.Drawing.Image.FromStream(new System.IO.MemoryStream(btsdata)))
            {
                img.Save(uploadDir, System.Drawing.Imaging.ImageFormat.Jpeg);//GDI+ 中发生一般性错误
            }
            context.Response.Write(base64);
        }
        catch (Exception ex)
        {
            LogHelper.WriteLog("Image.ashx", ex);
        }

在img.Save(uploadDir, System.Drawing.Imaging.ImageFormat.Jpeg);报错“GDI+ 中发生一般性错误”，看了下，“images/Shipping/2019”这个文件夹已创建

嗷找到原因了，我忘记uploadDir是虚拟路劲了，要加Server.MapPath
