Hi, My code is below. I am not able to extract the 'name' and 'query' lists from the JSON via a DataContracted Class (below) I have spent a long time trying to work this one out, and could really do with some help...

My Json string:

{"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\""}]}}

My code:

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?
}
