关于EF4.1更新数据后的显示问题-----PagedList

2种方式都可以更新成功，不过第一种更新成功后，我这里的显示总是有问题，不知道什么时候就出来了。很郁闷

 1         /// <summary>

 2         /// 推荐和取消

 3         /// Author:isaac zhang

 4         /// Date: 2012-04-11

 5         /// </summary>

 6         /// <param name="id">主键ID</param>

 7         /// <param name="type">操作类型</param>

 8         /// <returns>列表页面</returns>

 9         [HttpPost]

         public ActionResult News_TopOrNot(int id = 0, string ttype = "top")

         {

             NewInfo model = null;

             using (UBIQ_DB_JDZXContext db = new UBIQ_DB_JDZXContext())

             {

                 model = db.NewInfoes.AsNoTracking().First(c => c.NewID == id);

             }

             if (model == null)

             {

                 return HttpNotFound();

             }

             using (UBIQ_DB_JDZXContext db = new UBIQ_DB_JDZXContext())

             {

                 int tuijian = 1;

                 if (ttype != "top")

                 {

                     tuijian = 0;

                 }

                 model.IsTop = tuijian;

                 db.Database.ExecuteSqlCommand("Update NewInfo SET istop = @istop WHERE newid = @newid"

                     , new SqlParameter[] { new SqlParameter("@istop",model.IsTop), 

                         new SqlParameter("@newid",model.NewID)});

                 //db.NewInfoes.Attach(model);

                 //db.Entry(model).State = EntityState.Modified;

                 //var S = db.Database.SqlQuery<NewInfo>("SELECT * FROM NewInfo", null);

                 //db.SaveChanges();

             }

             return View("~/Views/Administrator/NewsAdmin/News_Manage.cshtml");

         }

注释的是显示有问题的更新方式，2种更新是都可以成功的哦～～

         public static string GetNewJson(Int32 pageIndex, Int32 pageCount, String sortname, String sortorder)

         {

             //取出记录总数

             var count = DataHelper.db.View_NewsInfoManage

                         .OrderByDescending(o => o.NewID).ToList().Count;

             List<View_NewsInfoManage> list = null;

             //根据排序type取数据

             if (sortorder.ToLower() == "desc")

             {

                 //list = DataHelper.db.View_NewsInfoManage

                 //        .OrderByDescending(o => o.NewID).ToPagedList(pageIndex, pageCount);

                 String sql = "SELECT * FROM View_NewsInfoManage order by  " + sortname + " " + sortorder;

                 list = DataHelper.db.Database.SqlQuery<View_NewsInfoManage>(sql).Skip((pageIndex - 1) * pageCount).Take(pageCount).ToList();

                 //DataHelper.db.Database.SqlQuery<View_NewsInfoManage>("SELECT * FROM NewInfo", null);

 

             }

             else

             {

                 list = DataHelper.db.View_NewsInfoManage

                         .OrderBy(o => o.NewID).ToPagedList(pageIndex, pageCount);

             }

同样，注释部分是只要更新后，就不能读到数据库的结果，而是直接从缓存（我认为的。）取了，新增和删除都不会出现这问题。。。。。。。。。。。。。太纠结了。。。


不过现在使用直接SQL 执行，不存在了，因为每次都是从数据库去读数据了。...................
