Counting trending tweets with geo

[SmhSemihSmh]

I am trying to find trending tweets number by each city in Turkey. but “TwitterGeoLocationSearch” result return zero . I am using TweetSharp 2.0 and visual studio 2010.

Please check my code block. Here:

private void btnTweetSearch_Click(object sender, EventArgs e)
        {
service = new TwitterService("xxxx", "xxxxx", "xxxxxxx", "xxxxxxxx");

 var  CityGeoCode = new TwitterGeoLocationSearch(37.0000000, 35.3213330, 10, TwitterGeoLocationSearch.RadiusType.Km);

 var tweetss = service.Search(new SearchOptions { Q = " Turkey ", Count = 1000, Geocode = CityGeoCode });
             
                int top = 1;

                var TweetwithGeo = tweetss.Statuses.Where(x => x.Location != null );
              
              foreach (var tweet in TweetwithGeo)
                {
                    TimeSpan diff = (DateTime.Now).Subtract(tweet.CreatedDate.ToLocalTime());
                    int control = Convert.ToInt32(diff.TotalMinutes);
                   if (control <= 150)
                    {

                        top++;
                        lbTweetWindow.Items.Add(tweet.Text);
                        lbtweettime.Items.Add(Convert.ToString(tweet.CreatedDate.ToLocalTime()));
                    }
                }
                lbltop.Text = Convert.ToString(top);
            } 
}

Any help would be very much appreciated. Thanks a lot…
