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

10         public ActionResult News_TopOrNot(int id = 0, string ttype = "top")
11         {
12             NewInfo model = null;
13             using (UBIQ_DB_JDZXContext db = new UBIQ_DB_JDZXContext())
14             {
15                 model = db.NewInfoes.AsNoTracking().First(c => c.NewID == id);
16             }
17             if (model == null)
18             {
19                 return HttpNotFound();
20             }
21             using (UBIQ_DB_JDZXContext db = new UBIQ_DB_JDZXContext())
22             {
23                 int tuijian = 1;
24                 if (ttype != "top")
25                 {
26                     tuijian = 0;
27                 }
28                 model.IsTop = tuijian;
29                 db.Database.ExecuteSqlCommand("Update NewInfo SET istop = @istop WHERE newid = @newid"
30                     , new SqlParameter[] { new SqlParameter("@istop",model.IsTop),
31                         new SqlParameter("@newid",model.NewID)});
32                 //db.NewInfoes.Attach(model);
33                 //db.Entry(model).State = EntityState.Modified;
34                 //var S = db.Database.SqlQuery<NewInfo>("SELECT * FROM NewInfo", null);
35                 //db.SaveChanges();
36             }
37             return View("~/Views/Administrator/NewsAdmin/News_Manage.cshtml");
38         }

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～～

12         {
13             //取出记录总数
14             var count = DataHelper.db.View_NewsInfoManage
15                         .OrderByDescending(o => o.NewID).ToList().Count;
16             List<View_NewsInfoManage> list = null;
17             //根据排序type取数据
18             if (sortorder.ToLower() == "desc")
19             {
20                 //list = DataHelper.db.View_NewsInfoManage
21                 //        .OrderByDescending(o => o.NewID).ToPagedList(pageIndex, pageCount);
22                 String sql = "SELECT * FROM View_NewsInfoManage order by  " + sortname + " " + sortorder;
23                 list = DataHelper.db.Database.SqlQuery<View_NewsInfoManage>(sql).Skip((pageIndex - 1) * pageCount).Take(pageCount).ToList();
24                 //DataHelper.db.Database.SqlQuery<View_NewsInfoManage>("SELECT * FROM NewInfo", null);
25
26             }
27             else
28             {
29                 list = DataHelper.db.View_NewsInfoManage
30                         .OrderBy(o => o.NewID).ToPagedList(pageIndex, pageCount);
31             }

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。...................
