Deserialize JSON of an unknown type (Google Map API)

I'm trying to work with the google maps api. This URL is EXACTLY what I need:

http://maps.googleapis.com/maps/api/geocode/json?address=77379

Take a look at the results. It has all the info I need... lat, lon, state, country. Trouble is, I don't know how to extract this data. I tried this:

var client = new WebClient();
var content = client.DownloadString("http://maps.googleapis.com/maps/api/geocode/json?address=77379");
object myObject = JsonConvert.DeserializeObject(content);

While that doesn't error out, myObject doesn't end up being anything useful. (Or, maybe it is and I just don't know it?)

Here is your class structure

public class AddressComponent
    {
        public string long_name { get; set; }
        public string short_name { get; set; }
        public List<string> types { get; set; }
    }

public class Northeast
{
    public double lat { get; set; }
    public double lng { get; set; }
}

public class Southwest
{
    public double lat { get; set; }
    public double lng { get; set; }
}

public class Bounds
{
    public Northeast northeast { get; set; }
    public Southwest southwest { get; set; }
}

public class Location
{
    public double lat { get; set; }
    public double lng { get; set; }
}

public class Northeast2
{
    public double lat { get; set; }
    public double lng { get; set; }
}

public class Southwest2
{
    public double lat { get; set; }
    public double lng { get; set; }
}

public class Viewport
{
    public Northeast2 northeast { get; set; }
    public Southwest2 southwest { get; set; }
}

public class Geometry
{
    public Bounds bounds { get; set; }
    public Location location { get; set; }
    public string location_type { get; set; }
    public Viewport viewport { get; set; }
}

public class Result
{
    public List<AddressComponent> address_components { get; set; }
    public string formatted_address { get; set; }
    public Geometry geometry { get; set; }
    public string place_id { get; set; }
    public List<string> postcode_localities { get; set; }
    public List<string> types { get; set; }
}

public class RootObject
{
    public List<Result> results { get; set; }
    public string status { get; set; }
}

And you have to do

RootObject rootObject = new JavaScriptSerializer().Deserialize<RootObject>(content);

Try referring to this stackoverflow posting if you would prefer other ways Deserialize JSON with C#

From my experience using JSON I have always used this method:

object myObject = JsonConvert.DeserializeObject(content);

Would that work? Or is this something different from what you're doing?
