How to pass anonymous type as a method parameter using dynamic with LINQ

    public class test
    {
        public static bool Process()
        {
            using (MyContext context = new MyContext())
            {
                var query = (from c in context.MyContents
                             join v in context.MyContentVersions
                                 on new { contentId = c.ContentId, verGmt = (DateTime)c.PubVerGmt }
                                 equals new { contentId = v.ContentId, verGmt = v.VerGmt }
                             where
                             c.PubVerGmt != null
                             && c.CatId == ConfigHelper.CatId
                             && System.Data.Objects.SqlClient.SqlFunctions.DateDiff("day", v.VerGmt, DateTime.Now) < ConfigHelper.Days
                             select new
                             {
                                 ContentId = v.ContentId,
                                 VerGmt = v.VerGmt,
                                 Body = v.Body,
                                 Format = c.FormatId,
                                 CatId = c.CatId
                             }).OrderByDescending(a => a.ContentId);


                IQueryable<dynamic> q = query as IQueryable<dynamic>;

                int maxNumberOfImage = ConfigHelper.MaxNumberOfImage;
                if (maxNumberOfImage > -1)
                {
                    q = q.Take(maxNumberOfImage);
                }

                return SaveImages(q);
            }
        }

        private static bool SaveImages(IEnumerable<dynamic> contents)
        {
            string filename = "";
            foreach (var item in contents)
            {
                filename = item.CatId + "-" + item.ContentId.ToString();
                using (MemoryStream memStream = new MemoryStream(item.Body))
                {
                    Bitmap bitmap = new Bitmap(memStream);
                    bitmap.Save(filename, ImageHelper.GetImageFormat(item.Format));
                }
            }

            return true;
        }
    }
