- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我一直致力于反序列化来自 API 的复杂 JSON 响应。我是 C# 和 .NET 的新手,所以我真的不知道如何继续。
我想做的事情:
我想收集 JSON 响应中的所有项目并将它们放入键值对中,然后将它们返回到控制台应用程序的列表中以用于测试目的。
当我调试时,它工作得非常好,我可以看到它按预期映射了所有键值对。我的努力是返回控制台应用程序列表中的所有内容。
这是我的“模型”类代码。

那么,任何人都可以帮助我了解如何将所有键值对从我的模型类返回到命令行吗?
如您所见,JSON 响应非常复杂,包含混合对象和数组。
最佳答案
您的 json 在语法上不正确 ( https://jsonlint.com/ ),据我所知,它不包含 ModelClass.Rootobject 的列表,而只包含此类的对象。尝试以下操作
