My JsonResult包含没有字段名称的值

这里的问题从底部的结果JSON数组中非常明显。从我的代码我无法确定为什么输出不包含字段名称（例如“dma”：“Albany-Schenectady-Troy”而不是“Albany-Schenectady-Troy”）。有人可以发现问题可能是什么？My JsonResult包含没有字段名称的值

型号

public IEnumerable<EstimateDetailsModel> GetEstimateDetails(int id) 
    { 
     var estimateDetails = from e in db.Estimates 
           join es in db.EstimateStations on e.EstimateID equals es.EstimateID 
           join s in db.Stations on es.StationID equals s.StationID 
           join m in db.Markets on s.MarketID equals m.MarketID 
           where e.EstimateID == 1 
           select new EstimateDetailsModel { Dma = m.DmaName, CallSign = s.CallSign, Description = s.StationDescription }; 
     return estimateDetails; 

    }

控制器

public JsonResult EstimateDetails(int id) 
    { 
     var details = estimatesRepository.GetEstimateDetails(id); 
     return this.Json(new { details = details }, JsonRequestBehavior.AllowGet); 
    }

生成的JSON

{"details":[["Albany-Schenectady-Troy","WRGB","WRGB (CBS) Schenectady"],["Albany-Schenectady-Troy","WTEN","WTEN (ABC) Albany "],["Albany-Schenectady-Troy","WXXA","WXXA (Fox) Albany "],["Atlanta","WGCL","WGCL (CBS) Atlanta "],["Atlanta","WXIA","WXIA (NBC) Atlanta "],["Austin","KXAN","KXAN (NBC) Austin "],["Austin","KVUE","KVUE (ABC) Austin "],["Baltimore","WMAR","WMAR (ABC) Baltimore "],["Baltimore","WBAL","WBAL (NBC) Baltimore"],["Baltimore","WJZ ","WJZ (CBS) Baltimore "],["Baltimore","WBFF","WBFF (Fox) Baltimore "]]}

编辑 - 这是我EstimateDetailsModel类

public class EstimateDetailsModel : IEnumerable<string> 
{ 
    public string Dma { get; set; } 

    public string CallSign { get; set; } 

    public string Description { get; set; } 

    public IEnumerator<string> GetEnumerator() 
    { 
     yield return Dma; 
     yield return CallSign; 
     yield return Description; 
    } 

    System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator() 
    { 
     return this.GetEnumerator(); 
    } 
}

您的EstimateDetailsModel类是否可串行化？并可能与重复http://stackoverflow.com/questions/6020889/asp-net-mvc-3-controller-json-method-serialization-doesnt-look-at-datamember-n – Jirapong 2012-01-18 04:38:15

@吉拉朋我认为这是，但我不确定。请参阅上面的修改。 – hughesdan 2012-01-18 04:43:24

删除模型中的所有枚举器代码。 – Joe 2012-01-18 04:44:14

您需要从模型中移除枚举器代码。它重写默认行为。
