Question

我正在开发一个利用VS2013中的MVC4和EF Data First的项目。尝试将对象传递给视图时出现此错误。

传递到字典中的模型项的类型是＆＃39; System.Data.Entity.Infrastructure.DbQuery 1[<>f__AnonymousType3 4 [System.String，System.Nullable 1[System.Int32],System.Nullable 1 [System.Int32 ]，System.Nullable 1[System.Int32]]]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable 1 [TitansMVCWithBootStrap.Models.Player_Game_Stats]＆＃39;

我不知道如何解决这个问题，任何建议都会有所帮助。感谢

控制器

 public class PlayerGameStatsController : Controller
{
    private Context db = new Context();

    // GET: PlayerGameStats/Details/5

    public ActionResult Details(int gid=19, int sid = 11)
    {

        var playerGameStats = from pgs in db.PlayerGameStats
                              join p in db.Players on pgs.Player_id equals p.id_player
                              where pgs.SeasonId == 11 && pgs.GameNumber == 19
                              select new
                              {
                                  p.PlayerName,
                                  pgs.PlateAppearance,
                                  pgs.Runs,
                                  pgs.Hits
                              };


        return View(playerGameStats);

    }

模型

 public class Player_Game_Stats
{
    [Key]
    [Column(Order = 0)]
    public int Player_id { get; set; }
    [Key]
    [Column(Order = 1)]
    public int GameNumber { get; set; }
    public Nullable<int> PlateAppearance { get; set; }
    public Nullable<int> Runs { get; set; }
    public Nullable<int> HR { get; set; }
    public int Hits{ get; set; }

    //[ForeignKey("id_player")]
    //public virtual Players Player { get; set; }
}
}

查看

@model IEnumerable<TitansMVCWithBootStrap.Models.Player_Game_Stats>
@{
ViewBag.Title = "Details";
Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Details</h2>

<table class="table table-striped">

<tr>

 <th>
        @Html.DisplayNameFor(model => model.PlayerName)
    </th>
 <th>
        @Html.DisplayNameFor(model => model.PlateAppearance)
    </th>
 <th>
        @Html.DisplayNameFor(model => model.Runs)
    </th>
 <th>
        @Html.DisplayNameFor(model => model.Hits)
    </th>

@foreach (var item in Model)
{

<tr>

<td>
        @Html.DisplayFor(modelItem => item.PlayerName)
    </td>
    <td>
        @Html.DisplayFor(modelItem => item.PlateAppearance)
    </td>
    <td>
        @Html.DisplayFor(modelItem => item.Runs)
    </td>
    <td>
        @Html.DisplayFor(modelItem => item.Hits)
    </td>
</tr>
}
</table>

也尝试了

    var playerGameStats = (from pgs in db.PlayerGameStats
                               join p in db.Players on pgs.Player_id equals p.id_player
                               where pgs.SeasonId == 11 && pgs.GameNumber == 19
                               select new Player_Game_Stats
                              {
                                  p.PlayerName,
                                  pgs.PlateAppearance,
                                  pgs.Runs,
                                  pgs.Hits
                              }).ToList();


        return View(playerGameStats);

试试这个：

public ActionResult Details(int gid=19, int sid = 11)
{

    var playerGameStats = from pgs in db.PlayerGameStats
                          join p in db.Players on pgs.Player_id equals p.id_player
                          where pgs.SeasonId == 11 && pgs.GameNumber == 19
                          select new TitansMVCWithBootStrap.Models.Player_Game_Stats
                          {
                              PlayerName = p.PlayerName,
                              PlateAppearance = pgs.PlateAppearance,
                              Runs = pgs.Runs,
                              Hits = pgs.Hits
                          };

    return View(playerGameStats);

}

查看无法正常工作，传递对象以查看错误
