我正在尝试使用c#,newtonsoft和.net 3.5对下面的设备json结构进行反序列化,因此put无法生成可用作" qxdddh"和" q0tL6au"是动态生成的名称。

最终为结构中的每个恒温器创建一个恒温类列表或数组(在本例中为" qxdddh"和" q0tL6au")。

{
    "thermostats": {
        "qxdddh": {
            "locale": "en-US",

            "name_long": "Den Thermostat",
            "is_online": true
        }
    }
}

代码的初始尝试是

    public class Devices
    {
        public TstatDetails[] thermostats { get; set; }
    }

    public class TstatDetails
    {
         public string locale { get; set; }
         public string temperature_scale { get; set; }
         public string is_using_emergency_heat { get; set; }
         public string has_fan { get; set; }
         public string software_version { get; set; }
         public string has_leaf { get; set; }
         public string device_id { get; set; }
         public string name { get; set; }
         public string can_heat { get; set; }
         public string can_cool { get; set; }
         public string hvac_mode { get; set; }
         public string target_temperature_c { get; set; }
         public string target_temperature_f { get; set; }
         public string target_temperature_high_c { get; set; }
         public string target_temperature_high_f { get; set; }
         public string target_temperature_low_c { get; set; }
         public string target_temperature_low_f { get; set; }
         public string ambient_temperature_c { get; set; }
         public string ambient_temperature_f { get; set; }
         public string away_temperature_high_c { get; set; }
         public string away_temperature_high_f { get; set; }
         public string away_temperature_low_c { get; set; }
         public string away_temperature_low_f { get; set; }
         public string structure_id { get; set; }
         public string fan_timer_active { get; set; }
         public string name_long { get; set; }
         public string is_online { get; set; }
    }

Devices tstats = (Devices) Newtonsoft.Json.JsonConvert.DeserializeObject<Devices>(jsonstring);

使用以下描述产生和例外

  

无法反序列化当前的JSON对象(例如{&#34; name&#34;:&#34; value&#34;})   进入类型&#39; NestTest.NestOAuth2 + TstatDetails []&#39;因为类型   需要一个JSON数组(例如[1,2,3])才能正确反序列化。

     

要修复此错误,请将JSON更改为JSON数组(例如   [1,2,3])或更改反序列化类型,使其成为正常的.NET   type(例如,不是像整数这样的基本类型,不是集合类型   像数组或List一样,可以从JSON对象反序列化。   JsonObjectAttribute也可以添加到类型中以强制它   从JSON对象反序列化。

我理解错误(我认为),但对c#相当新,我不确定如何纠正这种情况。

2 个答案:

答案 0 :(得分:2)

只需更改Devices课程即可使用Dictionary<,>代替数组:

public class Devices
{
    public Dictionary<string, TstatDetails> thermostats { get; set; }
}

JSON.NET会将JSON中thermostats对象的每个属性解释为字典中的条目,并相应地填充它。 (您的主叫代码保持不变。)

然后您将通过ID获得所有恒温器。例如:

TstatDetails details = tstats["qxdddh"];

一旦有效,我强烈建议您尝试使所有属性名称更加传统:)

答案 1 :(得分:0)

你的Json对象应该是一个数组,而不仅仅是一个对象。

它基本上应该包含[ .... ](其中你肯定有多个对象),而不是{ ... }

它可能看起来与此相似:

[
        {
            "locale": "en-US",
            "temperature_scale": "F",
            "is_using_emergency_heat": false,
            ...
        },
        {
            "locale": "en-US",
            "temperature_scale": "F",
            "is_using_emergency_heat": false,
            ...
        }
]

好吧,我无法与The Skeet竞争。 但我会留下我的答案,因为它也是正确的(只有一个选项来解决问题)。
