传入字典的模型项的类型为“System.Data.Objects.ObjectResult”1

Question

我正在尝试传递一个映射到名为ListLeagueLeaders() 的方法的存储过程，但调用存储过程的自动生成方法ObjectResult<ListLeagueLeaders_Result> ListLeagueLeaders() 需要一个ObjectResult 类型。我能做些什么来解决这个问题？

我曾想过使用 LINQ 而不是存储过程，但我想给这个策略最后一次机会。相关：LINQ to Entities instead of stored procedure?

HomeController

    public class HomeController : Controller
    {

        HockeyStatsEntities db = new HockeyStatsEntities();

        public ActionResult Index()
        {
            ViewBag.Message = "League leaders";
            {
                return View(db.ListLeagueLeaders());
            }
        }

        private ICollection<ListLeagueLeaders_Result> ListLeagueLeaders()
        {
            ICollection<ListLeagueLeaders_Result> leagueLeadersCollection = null;

            using (HockeyStatsEntities context = new HockeyStatsEntities())
            {
                foreach (ListLeagueLeaders_Result leagueLeader in
                          context.ListLeagueLeaders())
                {
                    leagueLeadersCollection.Add(leagueLeader);
                }
            }
            return leagueLeadersCollection;
        }
    }

Model1.Context.cs

public partial class HockeyStatsEntities : DbContext
    {

        public DbSet<Dim_Date> Dim_Date { get; set; }
        public DbSet<Dim_Player> Dim_Player { get; set; }
        public DbSet<Dim_Team> Dim_Team { get; set; }
        public DbSet<Fact_Statistics> Fact_Statistics { get; set; }
        public DbSet<Dim_Game> Dim_Game { get; set; }

        public virtual ObjectResult<ListLeagueLeaders_Result> ListLeagueLeaders()
        {
            ((IObjectContextAdapter)this).ObjectContext.MetadataWorkspace.LoadFromAssembly(typeof(ListLeagueLeaders_Result).Assembly);

            return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction<ListLeagueLeaders_Result>("ListLeagueLeaders");
        }
    }

查看：

@model NHLStats2.Models.ListLeagueLeaders_Result

@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

Answer 1

您的视图出现此错误。您需要引用从控制器操作中重新调整的相同对象类型。

例如，如果您从控制器操作返回 List<Foo> 类型，则只能将视图强类型化为 List<Foo> 或 IList<Foo> 或 IEnumerable<Foo> 等。
