Json快速转变为类

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。
