C#.net中的JSON Twitter列表

Question

我的代码如下.我无法通过DataContracted Class(下面)从JSON中提取"名称"和"查询"列表我花了很长时间尝试解决这个问题,并且可以真正做到一些帮助......

我的Json字符串:

{"as_of":1266853488,"trends":{"2010-02-22 
15:44:48":[{"name":"#nowplaying","query":"#nowplaying"},{"name":"#musicmonday","query":"#musicmonday"},{"name":"#WeGoTogetherLike","query":"#WeGoTogetherLike"},{"name":"#imcurious","query":"#imcurious"},{"name":"#mm","query":"#mm"},{"name":"#HumanoidCityTour","query":"#HumanoidCityTour"},{"name":"#awesomeindianthings","query":"#awesomeindianthings"},{"name":"#officeformac","query":"#officeformac"},{"name":"Justin 
Bieber","query":"\"Justin Bieber\""},{"name":"National 
Margarita","query":"\"National Margarita\""}]}}

我的代码:

WebClient wc = new WebClient();
wc.Credentials = new NetworkCredential(this.Auth.UserName, this.Auth.Password);
string res = wc.DownloadString(new Uri(link));
//the download string gives me the above JSON string - no problems
Trends trends = new Trends();
Trends obj = Deserialise<Trends>(res);


private T Deserialise<T>(string json)
{
    T obj = Activator.CreateInstance<T>();
    using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
    {
        DataContractJsonSerializer serialiser = new DataContractJsonSerializer(obj.GetType());
        obj = (T)serialiser.ReadObject(ms);
        ms.Close();
        return obj;
    }
}


[DataContract]
public class Trends 
{
    [DataMember(Name = "as_of")]
    public string AsOf { get; set; }

    //The As_OF value is returned - But how do I get the 
    //multidimensional array of Names and Queries from the JSON here?
} 

Answer 1

考虑这个例子：

public struct TwitterResponse
{
  public int32 as_of;
  public Trend[] Trends;
}

public struct Trends
{
  public String name;
  public String query;
}

Trend[] obj = JavaScriptConvert.DeserializeObject<TwitterResponse>( res ).Trends;

可能需要微调，但这就是如何做到这一点的总体思路。
