效果图：
补充：c#使用 Newtonsoft.Json 实现多态序列化
有时候会碰到以下情况
1.定义了一个类型为A的字段，但在实例化时使用的是它的派生类B。
2.定义了一个存储基类型A的集合，但实际上里面包含了各种各样的派生类。
上述两种情况在序列化的时候没有问题，但在反序列化的时候程序并不能将其转化为成派生类。
Newtonsoft.Json提供了一个JsonConverter特性，我们可以自定义某个数据的json读写方式以达成多态序列化的目的。
1.自定义转化类

2.使用方式
DataBase是自己定义的一个数据基类,按照以下写法，再利用Newtonsoft 的API 序列化和反序列化TestData就可以成功实现多态读写了。

以上为个人经验，希望能给大家一个参考，也希望大家多多支持服务器之家。如有错误或未考虑完全的地方，望不吝赐教。
