如何从url中检索Json作为字符串？

Question

我有一个返回JSON的URL。我正在开发一个Windows Phone应用程序，我想通过发送url来获取该json数据，然后将其转换为字符串并从中提取数据。我已经下载了json.net来阅读json数据。
我是否必须反序列化数据..是否有必要？
我不能以字符串格式获取数据，然后解析它。

我正在使用下面的代码来读取字符串格式的json数据。

Array Movies = jObject["movies"].ToArray(); 
foreach (JToken Movie in Movies) 
    MessageBox.Show(Movie["title"].ToString()); 

JSON的是这样的：

 
{"total":51,"movies":[{"id":"771242005","title":"Magic Mike","year":2012,"mpaa_rating":"R","runtime":110,"critics_consensus":"Magic Mike's sensitive direction, smart screenplay, and strong performances allow audiences to have their beefcake and eat it too.","release_dates":{"theater":"2012-06-29","dvd":"2012-10-23"},"ratings":{"critics_rating":"Certified Fresh","critics_score":79,"audience_rating":"Upright","audience_score":63},"synopsis":"Set in the world of male strippers, Magic Mike is directed by Steven Soderbergh and stars Channing Tatum in a story inspired by his real life.

我只希望影片名称和标题虽然。

如果你的问题是“是否需要反序列化”，那么答案是否定的，这是没有必要的。

也就是说，在使用数据服务器端时，将JSON字符串反序列化为强类型对象通常是首选，因为它可以减少运行时错误并使其更容易测试代码。

实施例使用JSON.Net：

public class Movie 
{ 
    public string Name { get; set; } 
    public string Title { get; set; } 
} 

public Movie Convert(string jsonString) 
{ 
    return JsonConvert.DeserializeObject<Movie>(jsonString); 
} 

有用于反序列化JSON到一个对象的其他选项。如果您有一个代表JSON对象的DataContract，则可以使用DataContractJsonSerializer。
