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 JSONPerson 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}

序列化

private static string ModelListToJson(List<JsonData> 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objectbool 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($"\"{itemArr.Name}\":");sb.Append(ModelListToJson(itemArr.JsonDatas));indexArr++;}}}if (!obj){sb.Append(ModelListToJson(item.JsonDatas));}sb.Append("]");break;case JsonDataType.Object:sb.Append($"\"{item.Name}\":");sb.Append(ModelListToJson(item.JsonDatas));break;default:break;}index++;}sb.Append("}");return sb.ToString();}

反序列化
