.NET根据类的值进行序列化反序列化操作
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(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();
}
public string MQTTName { get; set; }
public JsonDataTypeAttData{ get; set; }
public List JsonDatas{ get; set; }
}
public enum AttributeDataType
{
Int,
String,
Boolean,
Array,
Object
} 序列化
private static string ModelListToJson(List data)
{
StringBuilder sb = new StringBuilder();
sb.Append("{");
int index = 0;
foreach (var item in data)
{
if (index > 0)
{
sb.Append(",");
}
switch (item.AttData )
{
case JsonDataType.Int:
sb.Append($"\"{item.Name }\":0");
break;
case JsonDataType.String:
sb.Append($"\"{item.Name}\":\"\"");
break;
case JsonDataType.Boolean:
sb.Append($"\"{item.Name}\":\"false\"");
break;
case JsonDataType.Array:
sb.Append($"\"{item.Name}\":");
sb.Append("[");
//这里数据特殊，需要额外处理
int indexArr = 0;
//判断是否为object
bool obj = false;
if (item.JsonDatas .Count==1)
{
if (item.JsonDatas.FirstOrDefault().AttData == JsonDataType.Object)
{
obj = true;
foreach (var itemArr in item.JsonDatas)
{
if (indexArr > 0)
{
sb.Append(",");
}
//sb.Append($"\"{itemArr.Name}\":");
sb.Append(ModelListToJson(itemArr.JsonDatas));
indexArr++;
}
}
}
if (!obj)
{
sb.Append(ModelListToJson(item.JsonDatas));

break;

sb.Append(ModelListToJson(item.JsonDatas));
break;

index++;
}
sb.Append("}");
return sb.ToString();
