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 PublishSubscribJsonData() 
        {
            JsonDatas= new List<JsonData>();
        }
        public string MQTTName { get; set; }

        public JsonDataTypeAttData{ get; set; }

        public List<JsonData>  JsonDatas{ get; set; }
}
public enum AttributeDataType
{
    Int,
    String,
    Boolean,
    Array,
    Object

}
