将 JSON 命名属性反序列化为 .Net 对象

Posted 2023-03-31

【中文标题】将 JSON 命名属性反序列化为 .Net 对象

【英文标题】：Deserialize JSON named property to .Net Object

【发布时间】：2012-03-01 09:56:21

【问题描述】：

我使用的 API 提供了 JSON 负载。响应的一部分有一个包含命名对象数组的属性。我想我想将这部分反序列化为一个 .Net 列表，问题是数组中的每个对象都带有一个名称，所以我无法将它作为一个列表。

这是有效载荷：

我想要一个“ServiceOptions”列表。我很乐意使用 Json.Net 来执行此操作，但我又被难住了。。

【问题讨论】：

@Etienne de martel，你是如何格式化 JSON 的，我很努力但失败了？

像任何代码一样：只需将每行缩进 4 个空格（或者，更好的是，选择整个代码并按“代码”按钮）。如需更多信息，请阅读Editing Help。

【参考方案1】：

您所说的这种“命名对象数组”是一种众所周知的数据结构，称为dictionary 或ma​​p。 （对于 .NET，请参阅 this doc。）

只需将Dictionary<string, YourServiceOptionObject> 用于ServiceOptions 属性。

旁注：事实上，您可能提到的属性ServiceOptions 的结构与CheapestQuote 属性没有任何不同，除了每个键而不是原始的value 拥有另一个嵌套字典/对象的值。

看不到树上的木头。谢谢！
