含有动态未知字段的 JSON 反序列化

一般来说,正常的 json 长这个模样:

含有动态未知字段的 JSON 反序列化
{
  'Name': 'Bad Boys',
  'ReleaseDate': '1995-4-7T00:00:00',
  'Genres': [
    'Action',
    'Comedy'
  ]
}
含有动态未知字段的 JSON 反序列化

 

这个时候我们只需要建立对应的类,直接反序列化就行(比如宇宙第一VS的 “编辑” -- “选择性粘贴” -- “将JSON粘贴为类”)

含有动态未知字段的 JSON 反序列化
    public class Movie
    {
        public string Name { get; set; }
        public string ReleaseDate { get; set; }
        public string[] Genres { get; set; }
    }

    Movie m = JsonConvert.DeserializeObject<Movie>(json);

不过有的时候会有些不负责任的 JSON

有时候它长这样:

{
	"mapping": [{
		"PHARMACOLOGY": "TU",
		"NEUROSCIENCES": "RU"
	}]
}

 

有时候它还长这样:

{
	"mapping": [{
		"TELECOMMUNICATIONS": "YE"
	}]
}

 

这个时候序列化我们就需要 字典 (Dictionary)

这个时候我们的类要长这样:

    public class Rootobject
    {
        public List<Dictionary<string, string>> mapping { get; set; }
    }

 

然后照常反序列化:

Rootobject root = JsonConvert.DeserializeObject<Rootobject>(JSON);

 

循环下输出结果:

                        i++;
                        foreach (var temp in root.mapping[0])
                        {
                            Console.WriteLine(String.Format("Number:{0},Keys:{1},Values:{2}", i, temp.Key, temp.Value));
                        }

 

结果如下:

如果更麻烦一点的呢?

比如我在 https://blog.csdn.net/jdsjlzx/article/details/76785239 看到的这个json:

继续使用 Dictionary 定义类:

    public class WeatherRootobject
    {
        public string resultcode { get; set; }
        public string reason { get; set; }
        public Result result { get; set; }
        public int error_code { get; set; }
    }

    public class Result
    {
        public Sk sk { get; set; }
        public Today today { get; set; }
        public Dictionary<string, Weather> future { get; set; }
    }

    public class Sk
    {
        public string temp { get; set; }
        public string wind_direction { get; set; }
        public string wind_strength { get; set; }
        public string humidity { get; set; }
        public string time { get; set; }
    }

    public class Today
    {
        public string temperature { get; set; }
        public string weather { get; set; }
        public string wind { get; set; }
        public string week { get; set; }
        public string city { get; set; }
        public string date_y { get; set; }
        public string dressing_index { get; set; }
        public string dressing_advice { get; set; }
        public string uv_index { get; set; }
        public string comfort_index { get; set; }
        public string wash_index { get; set; }
        public string travel_index { get; set; }
        public string exercise_index { get; set; }
        public string drying_index { get; set; }
    }

    public class Weather
    {
        public string temperature { get; set; }
        public string weather { get; set; }
        public string wind { get; set; }
        public string week { get; set; }
        public string date { get; set; }
    }
含有动态未知字段的 JSON 反序列化

 

然后反序列化输出:

            WeatherRootobject weathers = JsonConvert.DeserializeObject<WeatherRootobject>(json);
            foreach (var temp in weathers.result.future)
            {
                Console.WriteLine(String.Format("Day:{0},Week:{1},Temperature:{2}",  temp.Key, temp.Value.week, temp.Value.temperature));
            }

 

结果如下:
