ASP.NET 核心对象列表返回“空”列表

Question

我的方法返回一个空列表：

这是我的代码：

    [HttpGet]
    [Route("GetDomoticzDevices")]
    public async Task<List<DomoticzDeviceStatus>> GetAsync() {
        KlevebrandContext dbContext = new KlevebrandContext();
        List<DomoticzDeviceStatus> domoticzDeviceStatuses = new List<DomoticzDeviceStatus>();

        foreach(var domoticzDevice in dbContext.TblDomoticzDevices.ToList())
        {
            var response = await client.GetAsync("http://10.0.0.11:8080/json.htm?type=devices&rid=" + domoticzDevice.Idx.ToString());

            domoticzDeviceStatuses.Add(new DomoticzDeviceStatus(domoticzDevice, ((JObject)JsonConvert.DeserializeObject(response.Content.ReadAsStringAsync().Result))["result"][0]["Data"].ToString(), ((JObject)JsonConvert.DeserializeObject(response.Content.ReadAsStringAsync().Result))["result"][0]["LastUpdate"].ToString()));
        }

        return domoticzDeviceStatuses;
    }

在我的调试器中，“domoticzDeviceStatuses”有 15 个具有设置值的对象，但在我的浏览器中它是空的。

这是调试器中的结果：

列表中有 porpper 值。

DomoticzDeviceStatus class 看起来像这样：

public class DomoticzDeviceStatus
{
    TblDomoticzDevice _tblDomoticzDevice;
    string _device_status;
    string _timestamp;

    public DomoticzDeviceStatus(TblDomoticzDevice tblDomoticzDevice, string device_status, string timestamp) { 
        _tblDomoticzDevice = tblDomoticzDevice;
        _device_status = device_status;
        _timestamp = timestamp;
    }
}

如果您需要更多信息，请告诉我:)

尝试将 model 中的字段更改为属性。

public class DomoticzDeviceStatus
{
    public TblDomoticzDevice TblDomoticzDevice {get; set;}
    public string Device_status {get; set;}
    public string Timestamp {get; set;}

    public DomoticzDeviceStatus(TblDomoticzDevice tblDomoticzDevice, string 
device_status, string timestamp) { 
        TblDomoticzDevice = tblDomoticzDevice;
        Device_status = device_status;
        Timestamp = timestamp;
    }
}
