Ok, I was playing around with the Twitter Trends http://search.twitter.com/trends/current.json.

I wanted to display the current trends on a page or wherever so I decided to give it a go with Linq to JSON, featured in JSON.NET.

I ran into some problems since the property in the json post is changing all the time so I don't have a static property to call in my code.

The easiest way that I found, was to replace the datetime tag with some static text and use that in my LINQ query.

So here goes:

using System;
using System.IO;
using System.Linq;
using System.Net;
using Newtonsoft.Json.Linq;

namespace TwitterCmd
{
  class Program
  {
    static void Main(string[] args)
    {
      string input = GetInput();
      string thisYear = DateTime.Now.Year.ToString();
      string date = input.Substring(input.IndexOf(thisYear), 19);
      input = input.Replace(date, "herewasdate");
      JObject trends = JObject.Parse(input);
      var TwitterTrends = from t in trends["trends"]["herewasdate"]
                          select t.Value<string>("name");
      foreach (var twitterTrend in TwitterTrends)
      {
        Console.WriteLine(twitterTrend);
      }
      Console.ReadLine();
    }

    private static string GetInput()
    {
      WebRequest request = WebRequest.Create("http://search.twitter.com/trends/current.json");
      request.Credentials = CredentialCache.DefaultCredentials;
      HttpWebResponse response = (HttpWebResponse)request.GetResponse();
      Stream dataStream = response.GetResponseStream();
      StreamReader reader = new StreamReader(dataStream);
      string input = reader.ReadToEnd();
      reader.Close();
      dataStream.Close();
      response.Close();
      return input;
    }
  }
}

This will list the current trends from Twitter.

Let me know if you know the way of querying a property that is ever changing! :)
