我知道有一些关于Newtonsoft的帖子，所以希望这不是一次重复……我试图将Kazaa的API返回的JSON数据转换为某种类型的漂亮对象
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JsonConvert行只是最近一个我正在尝试…我不太明白，希望通过问你们来消除一些步法。我本来是想把它转换成字典什么的……实际上，我只需要在那里抓住几个值，所以根据文档判断，也许Newtonsoft的LINQ到JSON可能是一个更好的选择?想法/链接?
下面是JSON返回数据的示例:

我做了更多的阅读，发现Newtonsoft的LINQ到JSON正是我想要的…使用WebClient，流，StreamReader，和Newtonsoft…我可以点击Kazaa获取JSON数据，提取URL，下载文件，这一切都在七行代码中完成!我很喜欢。
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();
这篇文章点击率很高，我认为在评论中加入“使用”的部分可能会有所帮助。
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"]);
}
