Question

在我的MVC足球应用程序的一些地方，我使用同一列使用订单，但只是在一个地方它的工作错误，我不知道为什么。

这是我的圆形模型：

public class Round : IValidatableObject
{

    public int RoundID { get; set; }
    public int RoundNumber { get; set; }
    public DateTime RoundStart { get; set; }
    public DateTime RoundEnd { get; set; }

    public virtual ICollection<Match> Matches { get; set; }
}

我的匹配模型：

public class Match
{

    public int MatchId { get; set; }
    public string HomeClubName { get; set; }
    public string AwayClubName { get; set; }

    public virtual Club HomeClub { get; set; }
    public virtual Club AwayClub { get; set; }

    public int? Club1Goals { get; set; }
    public int? Club2Goals { get; set; }

    [Required]
    public int RoundNumber { get; set; }

    [ForeignKey("RoundNumber")]
    [InverseProperty("Matches")]
    public virtual Round Round { get; set; }
}

我按来自Round类的RoundNumber列进行排序。它适用于我的整个项目：

return View(db.Round.ToList().OrderBy(s => s.RoundNumber));

它就像一个魅力。但是在一个地方它的工作是错误的。它位于匹配列表中（每个匹配都有一个整数）。这是以下代码：

public ActionResult Index()
{
    if (User.Identity.IsAuthenticated)
    {
        if (isAdminUser())
        {
            return View(db.Round.ToList().OrderBy(s => s.RoundNumber));
        }
        else return RedirectToAction("Index", "Home");
    }
    else
    {
        ViewBag.Name = "Not Logged IN";
    }
    return View(db.Round.ToList().OrderBy(s => s.RoundNumber));
}

我觉得可能会按RoundI而不是RoundNumber进行排序，因为我按以下顺序添加了回合：

20,21,22,23,24,25,19,18,1,3,33,32,11

测试我的理论，以及他们在这个特定视图中出现的顺序（我希望按照他们的数字对匹配进行排序）。这是创建新匹配的代码：

[Authorize]
public ActionResult Create()
{
    if (isAdminUser())
    {
        ViewBag.RoundNumber = new SelectList(db.Round.OrderBy(s => s.RoundNumber), "RoundID", "RoundNumber");
        ViewBag.AwayClubName = new SelectList(db.Clubs, "ClubName", "ClubName");
        ViewBag.HomeClubName = new SelectList(db.Clubs, "ClubName", "ClubName");
        return View();
    }
    else return RedirectToAction("Index", "Matches1");
}

[HttpPost]
[ValidateAntiForgeryToken]
[Authorize]
public ActionResult Create([Bind(Include = "MatchId,HomeClubName,AwayClubName,Club1Goals,Club2Goals,RoundNumber")] Models.Match match)
{
    if (isAdminUser())
    {
        if (ModelState.IsValid)
        {
            if (match.HomeClubName.Equals(match.AwayClubName))
            {
                ViewBag.RoundNumber = new SelectList(db.Round.OrderBy(s => s.RoundNumber), "RoundID", "RoundNumber", match.RoundNumber);
                ViewBag.AwayClubName = new SelectList(db.Clubs, "ClubName", "ClubName", match.AwayClubName);
                ViewBag.HomeClubName = new SelectList(db.Clubs, "ClubName", "ClubName", match.HomeClubName);
                return View(match);
            }
            db.Match.Add(match);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        ViewBag.RoundNumber = new SelectList(db.Round.OrderBy(s => s.RoundNumber), "RoundID", "RoundNumber", match.RoundNumber);
        ViewBag.AwayClubName = new SelectList(db.Clubs, "ClubName", "ClubName", match.AwayClubName);
        ViewBag.HomeClubName = new SelectList(db.Clubs, "ClubName", "ClubName", match.HomeClubName);
        return View(match);
    }
    else return RedirectToAction("Index", "Matches1");
}

它的观点：

    ViewBag.Title = "Add";

是否正在创建一个打破它的新匹配？ RoundNumber为int而不是string，因此它不是字母数字排序问题。它在单独显示轮次列表时或在创建匹配时在下拉列表中进行排序。

为什么它按RoundId（可能）排序而不是RoundNumber呢？如果有人知道发生了什么或如何解决它，我会非常感激。
