c# - 使用Newtonsoft将JSON反序列化为.NET对象(或者LINQ to JSON可能?)

我知道有一些关于newtonsoft的文章,所以希望这不是一个重复…我正在尝试将kazaa的api返回的json数据转换成某种很好的对象。

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();

那个jsonconvert线只是我最近尝试的一条线……我不太明白,我希望通过问你们来消除一些步法。我最初是想把它转换成字典之类的东西……实际上,我只需要在其中获取一些值,所以根据文档判断,牛顿的linq-to-json可能是更好的选择?想法/链接?
下面是JSON返回数据的示例:

  "page": 1,
  "total_pages": 8,
  "total_entries": 74,
  "q": "muse",
  "albums": [
    {

      "id": 60444,

      "id": 121171,
      "artist_name": "Muse"
    }
  ],
  "per_page": 10
}

我做了更多的阅读,发现牛顿的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,提取一个URL,下载文件,然后像七行代码一样完成所有操作!我喜欢。
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率,我认为将评论中讨论的“使用”部分包括在内可能会有所帮助。
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"]);
}


最佳答案:

如果您只需要从JSON对象中获取一些项目,我将使用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中非常有用,有时会因为缺少对象属性而让您吃惊,比如Twitter。
