我收到以下错误代码，如何解决？

我正在MVC4中创建一个应用程序。我的模型如下：我收到以下错误代码，如何解决？

public class NonComplianceData 
{ 
    public static List<MonthDefinitions> Months = new List<MonthDefinitions>() 
    { 
     new MonthDefinitions {Month = "January", Order = 1}, 
     new MonthDefinitions {Month = "February", Order = 2}, 
     new MonthDefinitions {Month = "March", Order = 3}, 
     new MonthDefinitions {Month = "April", Order = 4}, 
     new MonthDefinitions {Month = "May", Order = 5}, 
     new MonthDefinitions {Month = "June", Order = 6}, 
     new MonthDefinitions {Month = "July", Order = 7}, 
     new MonthDefinitions {Month = "August", Order = 8}, 
     new MonthDefinitions {Month = "September", Order = 9}, 
     new MonthDefinitions {Month = "October", Order = 10}, 
     new MonthDefinitions {Month = "November", Order = 11}, 
     new MonthDefinitions {Month = "December", Order = 12}, 
    }; 

    public int InspectorId { get; set; } 
    public string InspectorName { get; set; } 
    public IEnumerable<MonthData> FullYearData { get; set; } 
} 

public class MonthDefinitions 
{ 
    public string Month { get; set; } 
    public int Order { get; set; } 
} 

public class MonthData 
{ 
    public string Month { get; set; } 
    public int TotalAuditsCompleted { get; set; } 
    public int TotalNoDefects { get; set; } 
    public decimal NonComplianceRate 
    { 
     get 
     { 
     if (TotalAuditsCompleted == 0) 
     { 
      return 0; 
     } 
     else 
     { 
      return (TotalNoDefects/(decimal)TotalAuditsCompleted) * 100; 
     } 
     } 
    } 
}

我想用下面的填充数据：

var inspectorData = 
    context.COESDetails 
      .Where(x => 
       x.UploadCOESDetails.AuditZoneId == criteria.AuditZoneId && 
       x.UploadCOESDetails.AuditMonth.Contains(criteria.AuditYear)) 
      .Select(x => x.Inspector) 
      .Where(y => y.Id != 0) 
      .Distinct() 
      .OrderBy(x => x.Firstname) 
      .Select(ud => new NonComplianceData 
         { 
          InspectorId = ud.Id, 
          InspectorName = ud.Firstname + " " + ud.Surname, 
          FullYearData = 
           NonComplianceData.Months.Select(month => 
             new MonthData 
             { 
              Month = month.Month, 
             }) 
          });

，我得到以下错误

基地{} System.SystemException = {“无法创建类型为'AIS.Domain.Models.MonthDefinitions'的常量值。在此上下文中仅支持基本类型或枚举类型。”}
个

任何帮助，将不胜感激..谢谢

其他注意事项：

，如果我用这个

public static IEnumerable<string> Months = 
    new string[] { "January", "February", "March", "April", "May", "June", 
        "July", "August", "September", "October", "November", "December" };

问题是固定的，但我需要确保个月排序正确，这就是为什么我添加了订单属性

这个错误发生在哪里？ –

只需要知道，为什么不使用枚举器而不是创建列表？编辑：您的列表几个月基本上是一个枚举器，为什么要创建它？ – Vinicius

鉴于您的错误消息：

{“无法创建类型'AIS.Domain.Models.MonthDefinitions'的常量值。只有原始类型或枚举类型在这方面的支持。“}

我会说，你应该在你的SELECT子句，因为你正在使用的ORM添加toList()（大概实体框架？）不能将你的复杂对象Months以正确的查询
