前言：
在.NET种，序列化一般常用的方式是使用Newtonsoft.Json进行序列化和反序列化操作，比如创建一个Person类
public class Person
{
public string Name { get; set; }
public int Age { get; set; }
}
序列化为json
// 对象序列化为 JSON
Person person = new Person { Name = "张三李四", Age = 25 };
string json = JsonConvert.SerializeObject(person);
Console.WriteLine(json);得到的json如下
{"Name":"Alice","Age":25}反序列化
Person deserializedPerson = JsonConvert.DeserializeObject<Person>(json);以上方法是我们经常用的方法，但是现实中总有奇葩（跟我一起读：sha bi）的需求，以上序列化方式，是将Person的name序列化为json的key（name），将值序列化为json的值（Alice），但是如果有奇葩的需求，是反过来的，我们应该如何处理？
怎么处理？能怎么处理？还不得找办法解决

创建一个公用的类，用于构造数据
public class JsonData

{

}
public string MQTTName { get; set; }

public List<JsonData> JsonDatas{ get; set; }
}
public enum AttributeDataType
{
Int,
String,
Boolean,
Array,
Object
}序列化
private static string ModelListToJson(List<JsonData> data)
{
StringBuilder sb = new StringBuilder();
sb.Append("{");
int index = 0;
foreach (var item in data)

sb.Append(",");
}
switch (item.AttData )
