找到了更多的文本，但是JSONLint说JSON验证正确

Question

在很少情况下，当接收到消息时，“完成反序列化对象后在JSON字符串中找到其他文本”。我做的第一件事是使用JSONLint修复我的一些JSON结构错误。

然而，这一次，林特说json是有效的，我看不出问题出在哪里。(由于我不控制数据源，所以我需要将其序列化到一个泛型对象，然后遍历该对象。-这可能是我的错误吗？)

我正在用统一专用的Newtonsoft.Json (JsonNet)进行反序列化。

object resultData = JsonConvert.DeserializeObject<object>(jsonString);

我遗漏了什么？

JSON字符串

Answer 1

您选择的反序列化方法是在将一个著名的Json反序列化为与结构匹配的对象时使用的。在这种情况下，Json结构与System.Object类型结构不匹配，您正在尝试反序列化到。库抱怨说，Json中比System.Object结构中有更多的内容。

要解析任何Json对象，可以从Newtonsoft.Json文档中尝试一个示例

string json = @"{
  CPU: 'Intel',
  Drives: [
    'DVD read/writer',
    '500 gigabyte hard drive'
  ]
}";
JObject o = JObject.Parse(json);

您仍然需要遍历反序列化的对象。根据您想要实现的目标，寻找与Json结构匹配的.Net类(或者编写Json类)可能要好得多。
