将复杂的json转换为c＃类
我一直在尝试使用此网站和其他网站上类似问题的帮助将以下json数据反序列化为2天的类，并且可能会导致脑死亡。
我有这个json数据（长度道歉）并且正在尝试，作为开始获取'Values'数组中的'value'数字： -
{
"metadata": {
"columnGrouping": [
"area",
"metricType",
"period",
"valueType"
],
"rowGrouping": []
},
"columns": [
{
"area": {
"identifier": "E31000040",
"label": "Gtr Manchester Fire",
"altLabel": "Gtr Manchester Fire",
"isSummary": false
},
"metricType": {
"identifier": "948",
"label": "Accidental dwelling fires",
"altLabel": "Accidental dwelling fires",
"isSummary": false
},
"period": {
"identifier": "fq_Q1_2013_14",
"label": "2013/14 Q1",
"altLabel": "2013/14 Q1",
"isSummary": false
},
"valueType": {
"identifier": "raw",
"label": "Raw value",
"isSummary": false
}
},
{
"area": {
"identifier": "E31000040",
"label": "Gtr Manchester Fire",
"altLabel": "Gtr Manchester Fire",
"isSummary": false
},
"metricType": {
"identifier": "948",
"label": "Accidental dwelling fires",
"altLabel": "Accidental dwelling fires",
"isSummary": false
},
"period": {
"identifier": "fq_Q2_2013_14",
"label": "2013/14 Q2",
"altLabel": "2013/14 Q2",
"isSummary": false
},
"valueType": {
"identifier": "raw",
"label": "Raw value",
"isSummary": false
}
},
{
"area": {
"identifier": "E31000040",
"label": "Gtr Manchester Fire",
"altLabel": "Gtr Manchester Fire",
"isSummary": false
},
"metricType": {
"identifier": "948",
"label": "Accidental dwelling fires",
"altLabel": "Accidental dwelling fires",
"isSummary": false
},
"period": {
"identifier": "fq_Q3_2013_14",
"label": "2013/14 Q3",
"altLabel": "2013/14 Q3",
"isSummary": false
},
"valueType": {
"identifier": "raw",
"label": "Raw value",
"isSummary": false
}
},
{
"area": {
"identifier": "E31000040",
"label": "Gtr Manchester Fire",
"altLabel": "Gtr Manchester Fire",
"isSummary": false
},
"metricType": {
"identifier": "948",
"label": "Accidental dwelling fires",
"altLabel": "Accidental dwelling fires",
"isSummary": false
},
"period": {
"identifier": "fq_Q4_2013_14",
"label": "2013/14 Q4",
"altLabel": "2013/14 Q4",
"isSummary": false
},
"valueType": {
"identifier": "raw",
"label": "Raw value",
"isSummary": false
}
}
],
"rows": [
{
"values": [
{
"source": 515.0,
"value": 515.0,
"formatted": "515",
"format": "#,##0",
"publicationStatus": "Published"
},
{
"source": 264.0,
"value": 264.0,
"formatted": "264",
"format": "#,##0",
"publicationStatus": "Published"
},
{
"source": 254.0,
"value": 254.0,
"formatted": "254",
"format": "#,##0",
"publicationStatus": "Published"
},
{
"source": 455.0,
"value": 455.0,
"formatted": "455",
"format": "#,##0",
"publicationStatus": "Published"
}
]
}
]
}
我使用http://json2csharp.com/创建了类，并尝试过以下方法： -
RootObject ro = JsonConvert.DeserializeObject<RootObject>(json_data);
和
Value [] vo = JsonConvert.DeserializeObject<Value[]>(json_data);
和
dynamic result = JsonConvert.DeserializeObject(json_data);
也
JavaScriptSerializer jss = new JavaScriptSerializer();
Value [] thisval = jss.Deserialize<Value[]>(json_data);
其中。 什么是将他的信息提取到类中的正确方法，然后我可以处理它们。一旦反序列化调用数据的示例将是有帮助的。 我有的主要课程是
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; }
}

这是一个有效的dotNet小提琴，用于反序列化Values列表。 https://dotnetfiddle.net/7P2em6
加载小提琴时等待几秒钟，并在控制台窗口中注意输出。代码应该是不言自明的，但如果您需要帮助，请告诉我。
如果dotNetFiddle不可用，我也会在下面粘贴它以获得完整性。
控制台输出：
我使用http://json2csharp.com/从JSON字符串生成类。
我认为您的问题可能是Values在List对象中是Row，而List在RootObject内是Value }。换句话说，List被存储为List内的using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.IO;
using System.Net;
using System.Runtime.Serialization;
using System.Web;
using Newtonsoft.Json.Linq;
using Newtonsoft.Json;

完整的代码清单
columns 注意：对于columns对象，您不需要单独的字段类（json2csharp.com类生成器将默认为该类）。您可以将值存储在字典类中的{{1}}对象中（如果您知道它们的名称将是唯一的）。对于它的实现（不同的JSON字符串，但相同的json模式类型，原则），请看这个小提琴：https://dotnetfiddle.net/7bFcNM
答案 1 :(得分：2)
使用json到C＃生成器，如JSON C# Class Generator。
如果重命名属性并使它们与json的名称匹配，则可以使用Lists替换数组并删除JsonProperty属性。
这是输出：

public Metadata Metadata { get; set; }

public Column[] Columns { get; set; }
[JsonProperty("rows")]
public Row[] Rows { get; set; }
