问题描述

我一直在尝试反序列化下面的JSON数据转换成类利用这和其他网站类似的问题的帮助下2天,有可能会被持续脑死亡。



我有这样的JSON数据(道歉长度),我试图,作为开始,以获得价值数组中的价值数: -

  {
元数据:{
columnGrouping:[
区,
metricType,
时期,
值类型
],
rowGrouping:[]
},
柱:[
{
区:{
标识:E31000040,
标签:GTR曼彻斯特火,
altLabel:GTR曼彻斯特火,
isSummary :虚假
},
metricType:{
标识:948,

altLabel :意外住宅火灾,
isSummary:虚假
},
时期:{
标识:fq_Q1_2013_14,

altLabel:2013/14 Q1,

},

},
{

},

}
},
{
区:{

},

},
时期:{

},
值类型:{

}
},
{
区:{
标识:E31000040,

},

},
时期:{

标签:2013/14 Q4,
altLabel:2013/14 Q4,
isSummary:虚假
},
值类型:{
标识:原始,
标签:原始值,
isSummary:虚假
}
}
],
行:[
{
价值观:
{

格式化:515,

},

{
源:455.0,
值:455.0,
格式化:455,
格式:#,## 0,
publicationStatus :已发布
}
]
}
]
}

我已经用 http://json2csharp.com/ 类和尝试了这种方法如: -

  RootObject RO = JsonConvert.DeserializeObject< RootObject>(json_data); 

 值[] VO = JsonConvert.DeserializeObject<值[]>(json_data); 

 动态结果= JsonConvert.DeserializeObject(json_data); 



 的JavaScriptSerializer JSS =新的JavaScriptSerializer(); 
值[] = thisval&jss.Deserialize LT;值[]>(json_data);



等等。
什么是提取他的信息到阶级的正确途径于是我可以对他们的工作。一旦调用反序列化数据的例子将是有益的。
的主要类我是

 公共类值
{
公共双源{得到;组; }
公共double值{搞定;组; }
格式的公共字符串{搞定;组; }
公共字符串格式{搞定;组; }
公共字符串publicationStatus {搞定;组; }
}

公共类行
{
公开名单< VALUE>值{搞定;组; }
}

公共类RootObject
{
公开元数据元数据{搞定;组; }
公开名单<列>列{搞定;组; }
公开名单<行>行{搞定;组; }
}


解决方案

下面是一个工作的dotNet小提琴反序列化列表。 https://dotnetfiddle.net/7P2em6



等待几秒钟,当你加载小提琴,并注意在控制台窗口的输出。代码应该是不言自明的,但让我知道如果你需要帮助。



我也粘贴在它下面的完整性,以防dotNetFiddle不可用。





ALT =反序列化复杂JSON来的C#类>



我用 HTTP ://json2csharp.com/ 来从JSON字符串中的类



我觉得你的问题可能已在该列表的对象,而这又是在列表中的 RootObject 。换句话说, s的存储为列表列表

I have been trying to deserialize the following json data into classes for 2 days using the help from similar questions on this and other sites, and might possibly be going brain dead.

I have this json data (apologies for length) and am trying, as a start to get the 'value' number in the 'Values' array:-

          "publicationStatus": "Published"
        }
      ]
    }
  ]
}

I have created classes using http://json2csharp.com/ and have tried methods such as:-

RootObject ro = JsonConvert.DeserializeObject<RootObject>(json_data);

and

Value [] vo = JsonConvert.DeserializeObject<Value[]>(json_data);

and

dynamic result = JsonConvert.DeserializeObject(json_data);

also

JavaScriptSerializer jss = new JavaScriptSerializer();
Value [] thisval = jss.Deserialize<Value[]>(json_data);

Among others. What would be the correct way to extract his information into the classes so then i could work on them. An example of calling the data once deserialized would be helpful. The main classes I have are

public class Value
{
    public double source { get; set; }
    public double value { get; set; }
    public string formatted { get; set; }
    public string format { get; set; }
    public string publicationStatus { get; set; }
}

public class Row
{
    public List<Value> values { get; set; }
}

public class RootObject
{
    public Metadata metadata { get; set; }
    public List<Column> columns { get; set; }
    public List<Row> rows { get; set; }
}

解决方案

Here's a working dotNet Fiddle that deserializes the Values List. https://dotnetfiddle.net/7P2em6

Wait few seconds when you load the fiddle and notice the output in the Console window. The code should be self-explanatory, but let me know if you need help.

I have also pasted it below for completeness in case dotNetFiddle is not available.

Console Output:

I used http://json2csharp.com/ to generate the classes from the JSON string.

I think your issue might have been that Values is a List inside the Row object, which, in turn, is a List inside the RootObject. In other words, Values are stored as a List inside a List.

NOTE: For the columns object, you don't need separate classes for the fields (json2csharp.com class generator will default to that). You can store the values in the columns object in a dictionary class (if you know that their names will be unique). For an implementation of that (different JSON string, but same json schema type, principle) see this fiddle: https://dotnetfiddle.net/7bFcNM
