使用 Newtonsoft 将 JSON 反序列化为 .NET 对象或者可能是 LINQ to JSON？

如何解决使用 Newtonsoft 将 JSON 反序列化为 .NET 对象或者可能是 LINQ to JSON？

如果您只需要从 JSON 对象中获取一些项目，我会使用 Json.NET 的 LINQ to JSONJObject类。例如：

JToken token = JObject.Parse(stringFullOfJson);

int page = (int)token.SelectToken("page");
int totalPages = (int)token.SelectToken("total_pages");

我喜欢这种方法，因为您不需要完全反序列化 JSON 对象。这在 API 中派上用场，这些 API 有时会因缺少对象属性而让您感到惊讶，例如 Twitter。

解决方法

我知道有一些关于 Newtonsoft 的帖子，所以希望这不是重复……我正在尝试将 Kazaa 的 API 返回的 JSON 数据转换为某种不错的对象

WebClient client = new WebClient();
Stream stream = client.OpenRead("http://api.kazaa.com/api/v1/search.json?q=muse&type=Album");
StreamReader reader = new StreamReader(stream);

List<string> list = Newtonsoft.Json.JsonConvert.DeserializeObject<List<string>>(reader.Read().ToString());

foreach (string item in list)
{
    Console.WriteLine(item);
}

//Console.WriteLine(reader.ReadLine());
stream.Close();

那条 JsonConvert
线只是我最近尝试的一条……我不太明白，希望通过询问你们来消除一些步法。我最初试图将它转换成字典或其他东西......实际上，我只需要在那里获取几个值，所以从文档来看，也许
Newtonsoft 的 LINQ to JSON 可能是一个更好的选择？想法/链接？

以下是 JSON 返回数据的示例：

{
  "page": 1,"total_pages": 8,"total_entries": 74,"q": "muse","albums": [
    {
      "name": "Muse","permalink": "Muse","cover_image_url": "http://image.kazaa.com/images/69/01672812 1569/Yaron_Herman_Trio/Muse/Yaron_Herman_Trio-Muse_1.jpg","id": 93098,"artist_name": "Yaron Herman Trio"
    },{

    }
  ],"per_page": 10
}

我做了更多阅读，发现 Newtonsoft 的 LINQ to JSON 正是我想要的……使用 WebClient、Stream、StreamReader
和 Newtonsoft……我可以点击 Kazaa 获取 JSON 数据，提取 URL，下载文件，然后执行全部都在七行代码中！我喜欢它。

WebClient client = new WebClient();
Stream stream = client.OpenRead("http://api.kazaa.com/api/v1/search.json?q=muse&type=Album");
StreamReader reader = new StreamReader(stream);

Newtonsoft.Json.Linq.JObject jObject = Newtonsoft.Json.Linq.JObject.Parse(reader.ReadLine());

// Instead of WriteLine,2 or 3 lines of code here using WebClient to download the file
Console.WriteLine((string)jObject["albums"][0]["cover_image_url"]);
stream.Close();

这篇文章获得了如此多的点击，我认为包含评论中讨论的“使用”位可能会有所帮助。

using(var client = new WebClient())
using(var stream = client.OpenRead("http://api.kazaa.com/api/v1/search.json?q=muse&type=Album"))
using (var reader = new StreamReader(stream))
{
    var jObject = Newtonsoft.Json.Linq.JObject.Parse(reader.ReadLine());
    Console.WriteLine((string) jObject["albums"][0]["cover_image_url"]);
}
