c# java deserialization issue

Question

I'm trying to loop through a json file and retrieve the title of each record from a yahoo api. Can someone please give me some pointers as to how I need to do this. My code is as follows:

   HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20local.search%20where%20query%3D%22sushi%22%20and%20location%3D%22san%20francisco%2C%20ca%22&format=json&diagnostics=true&callback=cbfunc");
            HttpWebResponse rep = (HttpWebResponse)req.GetResponse();

            StreamReader sr = new StreamReader(rep.GetResponseStream());

            string data = sr.ReadToEnd();

            //Console.WriteLine(data); 

            var jss = new JavaScriptSerializer();
            var dict = jss.Deserialize<Dictionary<string,string>>(data);

You could design a couple of classes to match the JSON structure returned by yahoo. Also don't use the callback=cbfunc parameter because otherwise yahoo returns JSONP instead of JSON:

using System;
using System.Net;
using System.Web.Script.Serialization;

public class YahooResponse
{
    public Query Query { get; set; }
}

public class Query
{
    public Results Results { get; set; }
}

public class Results
{
    public Result[] Result { get; set; }
}

public class Result
{
    public string Title { get; set; }
}

class Program
{
    static void Main()
    {
        using (var client = new WebClient())
        {
            var json = client.DownloadString("http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20local.search%20where%20query%3D%22sushi%22%20and%20location%3D%22san%20francisco%2C%20ca%22&format=json&diagnostics=true")
            var jss = new JavaScriptSerializer();
            var result = jss.Deserialize<YahooResponse>(json);
            foreach (var item in result.Query.Results.Result)
            {
                Console.WriteLine(item.Title);
            }

        }
    }
}
