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

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～～

{

//list = DataHelper.db.View_NewsInfoManage

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。...................
