一般来说，正常的 json 长这个模样：
{
'Name': 'Bad Boys',
'ReleaseDate': '1995-4-7T00:00:00',
'Genres': [
'Action',
'Comedy'
]
}
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”）
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：
{
"resultcode": "200",
"reason": "successed!",
"result": {
"sk": {
"temp": "24",
"wind_direction": "东北风",
"wind_strength": "2级",
"humidity": "28%",
"time": "17:38"
},
"today": {
"temperature": "15℃~26℃",
"weather": "多云转晴",
"wind": "东北风微风",
"week": "星期日",
"city": "桂林",
"date_y": "2015年10月11日",
"dressing_index": "舒适",
"dressing_advice": "建议着长袖T恤、衬衫加单裤等服装。年老体弱者宜着针织长袖衬衫、马甲和长裤。",
"uv_index": "弱",
"comfort_index": "",
"wash_index": "较适宜",
"travel_index": "较适宜",
"exercise_index": "较适宜",
"drying_index": ""
},
"future": {
"day_20151011": {
"temperature": "15℃~26℃",
"weather": "多云转晴",
"wind": "东北风微风",
"week": "星期日",
"date": "20151011"
},
"day_20151012": {
"temperature": "16℃~27℃",
"weather": "晴转多云",
"wind": "微风",
"week": "星期一",
"date": "20151012"
},
"day_20151013": {
"temperature": "16℃~26℃",
"weather": "多云转晴",
"wind": "微风",
"week": "星期二",
"date": "20151013"
},
"day_20151014": {
"temperature": "17℃~27℃",
"weather": "晴",
"wind": "北风微风",
"week": "星期三",
"date": "20151014"
},
"day_20151015": {
"temperature": "17℃~28℃",
"weather": "晴",
"wind": "北风微风",
"week": "星期四",
"date": "20151015"
},
"day_20151016": {
"temperature": "17℃~30℃",
"weather": "晴",
"wind": "北风微风",
"week": "星期五",
"date": "20151016"
},
"day_20151017": {
"temperature": "17℃~30℃",
"weather": "晴",
"wind": "北风微风",
"week": "星期六",
"date": "20151017"
}
}
},
"error_code": 0
}
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; }
}
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：
