C# 异常：指定的类型成员'；LineColor'；在LINQ to实体中不支持

我在使用linq分配字节[]中的值时遇到以下异常

LINQ to实体中不支持指定的类型成员“LineColor”。只支持初始值设定项、实体成员和实体导航属性

下面是代码

(from v in _DWEntities.DimScheduleJourneys
                join od in _DWEntities.OperatingDateVehicleJourneyMappings on v.VehicleJourneyUID equals od.VehicleJourneyUID
                where od.OperatingDateKey == _operatingDate && (vehicleJourneyUID == null || v.VehicleJourneyUID == vehicleJourneyUID)
                && (v.ScheduleDeparture != null && v.ScheduleDeparture != "" && v.ScheduleArrival != null && v.ScheduleArrival != "")
                select new ScheduleJourney
                {

                    LineName = v.LineName,
                    LineColor = v.LineColor,
                    //LineColor = v.LineName,

                    DeadRunStartTime = v.DeadRunStartTime,

                    MarketingName = v.MarketingName,
                    PrivateCode = v.PrivateCode,
                    //   GarageID = v.GarageID,
                    GarageCode = v.GarageCode,
                    IsFrequentService = v.FrequentService.HasValue ? v.FrequentService.Value : false,
                    FrequentServiceInterval = v.ScheduleFrequency,
                    Origin = v.Origin,
                    Destination = v.Destination,
                    IsMasterJourney = v.IsMasterJourney
                });

这里我的线条颜色是byte[]

请帮助解决此异常

提前感谢

您能在实体类中发布整个LineColor声明吗？LineColor没有标记为NotMapping，对吗？在sql中，LineColor数据类型为varbinary，实体（C#）类为byte[]。所以每次实体在行颜色中取空值。根据我的RND实体无法获取varbinary数据类型值。我不确定，但由于null Linq无法处理，您可以在实体类中发布整个LineColor声明吗？LineColor未标记为NotMapped，对吗？在sql中，LineColor数据类型为varbinary，实体（C#）类为byte[]。所以每次实体在行颜色中取空值。根据我的RND实体无法获取varbinary数据类型值。我不确定，但由于null，Linq无法处理
