我想用我的 EF 查询得到一个嵌套的 JSON 回复，但不知道该怎么做。我已将我的模型声明如下：

  [Serializable]
    public class StockReturnMethod
    {
        public int WarehouseID { get; set; }
        public int ProductSKUID { get; set; }
        public int LotID { get; set; }
        public string LotName { get; set; }
        public int AreaID { get; set; }
        public string AreaName { get; set; }
        public int BinID { get; set; }
        public string BinName { get; set; }
        public List<AvailibleStock> Stock { get; set; }
    }


  [Serializable]
    public class AvailibleStock
    {
        public int WarehouseID { get; set; }
        public int ProductSKUID { get; set; }
        public string ProductSKUName { get; set; }
        public string WarehouseName { get; set; }
        public string Status { get; set; }
        public int QtyUnassigned { get; set; }
    }

这是我到目前为止的 EF 查询。

    {
       return (from WH in SCMENT.Warehouses 
               join WL in SCMENT.WarehouseLots on WH.WarehouseID equals WL.WarehouseID
               join WA in SCMENT.WarehouseAreas on WL.WarehouseLotID equals WA.WarehouseLotID
               join WB in SCMENT.WarehouseBins on WA.WarehouseAreaID equals WB.WarehouseAreaID
               join SLI in SCMENT.StockLineItems on WH.WarehouseID equals SLI.WarehouseID
               join PSKU in SCMENT.ProductSKUs on SLI.ProductSKUID equals PSKU.ProductSKUID
               where SLI.SystemAreaID == 1

               select new StockReturnMethod() 
               {
                WarehouseID = WH.WarehouseID,
                LotID = WL.WarehouseLotID,
                LotName = WL.WarehouseLotName,
                AreaID = WA.WarehouseAreaID,
                AreaName = WA.WarehouseAreaName,
                BinID = WB.WarehouseBinID,
                BinName = WB.WarehouseBinName,
                ProductSKUID = PSKU.ProductSKUID,
                Stock = (Will I create a sub query here?)


               }

    )

public List<AvailibleStock> Stock { get; set; }

将其更改为：

public IList<AvailibleStock> Stock { get; set; }

编辑：这是我的一个项目的工作示例，您可以将其用作参考：

public class StatisticsModel
{
    public int Id { get; set; }
    public int ClientId { get; set; }
    public int Opened { get; set; }
    public IEnumerable<LocationsModel> Locations { get; set; }
}


public class LocationModel
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int OpenCount { get; set; }
}


return dbSet.Select(x => new StatisticsModel
{
    Id = x.Id,
    ClientId = x.ClientId,
    Opened = x.OpenCount,
    Locations = x.Locations.Select(z => new LocationsModel{
        Id = z.Id,
        Name = z.Store.Name,
        OpenCount = z.OpenCount
    })
})
