If you have JSON that you want to deserialize, and you don‘t have the class to deserialize it into, you have options other than manually creating the class that you need:
Use JsonDocument and Utf8JsonReader directly.
Use Visual Studio 2019 to automatically generate the class you need:
Copy the JSON that you need to deserialize.
Create a class file and delete the template code.
Choose Edit > Paste Special > Paste JSON as Classes. The result is a class that you can use for your deserialization target.
要点：
- 复制json的内容
- 新建一个类文件
- 粘贴特别，粘贴为Json类或者XML类
非常神奇。
