我遇到了WCF Restfull Web服务的问题，问题在于其他方法正常工作的一种方法，那么我认为这不是一般配置问题。 我知道可能是什么问题，但实际上我不知道如何解决它。 该方法可以访问第三方Web服务以检索以下类的对象：
[DataContract]
public class DeviceData
{
[DataMember]
public int DeviceDataFull { get; set; }
[DataMember]
public string DeviceDataVersion { get; set; }
[DataMember]
public string DeviceDataModel { get; set; }
[DataMember]
public int DeviceDataZWave_Heal { get; set; }
[DataMember]
public string DeviceDataTemperature { get; set; }
[DataMember]
public string DeviceDataSkin { get; set; }
[DataMember]
public string DeviceDataSerial_Number { get; set; }
[DataMember]
public string DeviceDataFWD1 { get; set; }
[DataMember]
public string DeviceDataFWD1Token { get; set; }
[DataMember]
public string DeviceDataFWD2 { get; set; }
[DataMember]
public string DeviceDataFWD2Token { get; set; }
[DataMember]
public int DeviceDataMode { get; set; }
[DataMember]
public List<Section> DeviceDataSections { get; set; }
[DataMember]
public List<Room> DeviceDataRooms { get; set; }
[DataMember]
public List<Scene> DeviceDataScenes { get; set; }
[DataMember]
public List<DeviceItem> DeviceDataItems { get; set; }
[DataMember]
public List<Category> DeviceDataCategories { get; set; }
[DataMember]
public int DeviceDataIr { get; set; }
[DataMember]
public string DeviceDataIrtx { get; set; }
[DataMember]
public int DeviceDataLoadTime { get; set; }
[DataMember]
public int DeviceDataState { get; set; }
[DataMember]
public string DeviceDataComment { get; set; }
}
我在方法代码中唯一做的就是填充这个对象，在我试图得到的代码片段中：public List<DeviceItem> DeviceDataItems { get; set; }是问题，因为我在没有它的情况下测试方法并且工作完美。此DeviceItem列表包含设备项的继承类对象：
DeviceItemPanel : DeviceItem
DeviceItemPanelPartition : DeviceItem
DeviceItemDimmable : DeviceItem
DeviceItemThermostat : DeviceItem
etc..
我的问题：在服务架构中是否有任何限制来返回我在上面解释的对象类？ 因为当我执行该方法时它仍然加载，几秒钟后我得到消息： ERR_CONNECTION_RESET ，我没有看到任何其他错误代码或其他任何东西，我也调试方法，一切正常问题是当它尝试将对象作为JSON格式返回时。 如果有人能帮我找到解决方案，我会非常感激。 请注意webservice方法的代码：

答案 0 :(得分：0)
我解决了在方法中返回字符串，并在代码中序列化对象的问题。
return JsonConvert.SerializeObject(result);
