小编war*_*rdh的帖子

我正在尝试在表中选择前五个最常用的值并将它们返回到List中.

    var mostFollowedQuestions = (from q in context.UserIsFollowingQuestion
                                 select *top five occuring values from q.QuestionId*).toList();

任何的想法？

谢谢

我正在尝试使用MVC和Razor填充带有List的@ Html.DropDownList.贝娄是我的控制器代码.所以我需要从ViewBag中选择列表并填写下拉列表.

public ActionResult Register()
    {
        sparklingEntities context = new sparklingEntities();
        var query = (from discs in context.Disciplines
                     select discs).ToList();
        List<string> listOfDiscs = new List<string>();
        foreach (var item in query)
        {
            listOfDiscs.Add(item.Discipline);
        }
        ViewBag.ListOfDisciplines = listOfDiscs;
        return View();
    }

谢谢您的帮助.
