        String message = "";
        MyProjectsEntities db = new MyProjectsEntities();

            var file = Request.Files[0];

            try
            {
                if (file != null && file.ContentLength > 0)
                {
                    var content = new byte[file.ContentLength];
                    file.InputStream.Read(content, 0, file.ContentLength);
                    pro.Files = content;
                    db.Projects.Add(pro);
                    db.SaveChanges();
                    message = "Success";
                    Status = true;
                }

            }
            catch (DbEntityValidationException e)
            {
                foreach (var eve in e.EntityValidationErrors)
                {
                    message = " Entity of type \"{0}\" in state \"{1}\" has the following validation errors:" + eve.Entry.Entity.GetType().Name + " " + eve.Entry.State;
                    //Console.WriteLine("Entity of type \"{0}\" in state \"{1}\" has the following validation errors:",
                    //    eve.Entry.Entity.GetType().Name, eve.Entry.State);
                    foreach (var ve in eve.ValidationErrors)
                    {
                        message = "- Property: \"{0}\", Error: \"{1}\"" + ve.PropertyName + " " + ve.ErrorMessage;
                        //Console.WriteLine("- Property: \"{0}\", Error: \"{1}\"",
                        //    ve.PropertyName, ve.ErrorMessage);
                    }
                }
                //throw;
            }


        ViewBag.Message = message;
        ViewBag.Status = Status;
        return RedirectToAction("FileUpload");
    }
