Json.net 序列化/反序列化派生类型? [英] Json.net serialize/deserialize derived types?

问题描述

json.net (newtonsoft)
我正在浏览文档，但找不到任何关于此的信息或最佳方法.

json.net (newtonsoft)
I am looking through the documentation but I can't find anything on this or the best way to do it.

public class Base
{
    public string Name;
}
public class Derived : Base
{
    public string Something;
}

JsonConvert.Deserialize<List<Base>>(text);

现在我在序列化列表中有派生对象.如何反序列化列表并取回派生类型?

Now I have Derived objects in the serialized list. How do I deserialize the list and get back derived types?

推荐答案

如果你在你的 text 中存储类型(你应该在这个场景中)，你可以使用 JsonSerializerSettings.

If you are storing the type in your text (as you should be in this scenario), you can use the JsonSerializerSettings.

不过要小心.使用除TypeNameHandling = TypeNameHandling.None 以外的任何东西都可能让一个安全漏洞.

Be careful, though. Using anything other than TypeNameHandling = TypeNameHandling.None could open yourself up to a security vulnerability.
