我被困在这项工作中，请帮助我..

任何帮助都会很棒。或者关于如何解析 Json 的一点线索也足够了。

使用出色的Json.net库。

特征

Flexible JSON serializer for converting between .NET objects and JSON
LINQ to JSON for manually reading and writing JSON
High performance, faster than .NET's built-in JSON serializers
Write indented, easy to read JSON
Convert JSON to and from XML
Supports .NET 2, .NET 3.5, .NET 4, Silverlight and Windows Phone

当您正在读取或写入的 JSON 映射到 .NET 类时，序列化程序是一个不错的选择。

LINQ to JSON 适用于您只对从 JSON 获取值感兴趣、没有要序列化或反序列化到的类、或者 JSON 与您的类完全不同并且您需要从您的类中手动读取和写入的情况对象。

似乎您需要将 JSON 字符串反序列化为对象。您可以创建一个代表对象的类，然后将 json 反序列化为它。

就像是

class Information
{
   int id;
   string name;
   string telephone;
   // etc
}

然后用这样的东西反序列化

JavaScriptSerializer json_serializer = new JavaScriptSerializer();
// Using List<T> as the JSON is organised like an array
List<Information> info = (List<Information >)json_serializer.DeserializeObject(JSONFeed);

JSONFeed网站上的 json 字符串在哪里。
