使用JSON反序列化JSON块和嵌套的嵌入对象数组.网络失败
本文关键字：JSON 对象 数组 网络 失败 反序列化 嵌套 使用 | 更新日期: 2023-09-27 18:17:42
下面是一个JSON响应从一个REST API调用我在Windows商店应用程序(Win 8.1)。它包含来自REST API调用的一页结果，每个结果(行)是一个PropertyMaster记录/对象。下面是Visual Studio 2013使用Paste Special as JSON IDE特性创建的JSON类。正如您所看到的，PropertyMaster对象有一个addresses字段，该字段是一个Address对象数组。如果您查看JSON，您将看到第一个结果在addresses JSON数组中确实有一个有效的Address对象。但是，当我使用以下调用反序列化JSON响应时:
JsonConvert.DeserializeObject<PropertyRecordsResponse>(json);
地址PropertyMaster对象中的字段为NULL。我没有得到JSON抛出的任何异常。. NET那么为什么不地址 JSON数组的内容被正确解析成地址对象的数组?任何关于如何跟踪和解决这个问题的建议都是值得赞赏的。
注意:我确实找到了这篇关于反序列化嵌套对象数组的文章:
用json数组的数组反序列化json字符串。净
但是我发誓我以前在JSON中有过嵌套的对象数组，并且不需要采取特殊的操作来反序列化它们。

看起来address不在JSON中的正确位置。尝试反序列化这个(地址在第二条记录中):
