civic address in wp8

I am working on a wp8 project and need to find the location . I've used windows.device.geoloaction name space to find the lattitude and longitude now I need to find the address(country state and zip). I found this example but I am confused how to pass the coordinates that I obtained . Here is my code.

public async void FindTADeviceLocation()
{
    ////Declare  Geolocator object
    Geolocator geolocator = new Geolocator();

    //  Set user's accuracy 
    geolocator.DesiredAccuracy = PositionAccuracy.High;

    //get the position of the user.
    try
    {
        //The await guarantee the calls  to be returned on the thread from which they were called

        Geoposition geoposition = await geolocator.GetGeopositionAsync(
            maximumAge: TimeSpan.FromMinutes(1),
            timeout: TimeSpan.FromSeconds(10)
            );

        var geoQ = new ReverseGeocodeQuery();
        geoQ.QueryCompleted += geoQ_QueryCompleted;

        if (geoQ.IsBusy == true)
        {
            geoQ.CancelAsync();
        }
        // Set the geo coordinate for the query
        geoQ.GeoCoordinate = geoposition.Coordinate;

        geoQ.QueryAsync();

    }

    catch (Exception ex)
    {
        if ((uint)ex.HResult == 0x80004004)
        {
            MessageBox.Show("position is unknown");
        }

    } 
}


void geoQ_QueryCompleted(object sender, QueryCompletedEventArgs<IList<MapLocation>> e)
{      
    if (e.Result.Count() > 0)
    {
        string showString = e.Result[0].Information.Name;
        showString = showString + "\nAddress: ";
        showString = showString + "\n" + e.Result[0].Information.Address.PostalCode + " " + e.Result[0].Information.Address.City; 
        showString = showString + "\n" + e.Result[0].Information.Address.Country + " " + e.Result[0].Information.Address.CountryCode;
        showString = showString + "\nDescription: ";
        showString = showString + "\n" + e.Result[0].Information.Description.ToString();

        MessageBox.Show(showString);
    }   
}

I know the problem is in the line geoQ.GeoCoordinate = geoposition.Coordinate;

But how can I pass the coordinates to geoQ.GeoCoordinate?

Thanks in adwance

This is done. The geocordinate takes arguments of the type double. so all we've to do is to convert the cordiantes into double and pass it.

var currentLocationLatitude = Convert.ToDouble(geoposition.Coordinate.Latitude.ToString("0.0000000000000"));
var currentLocationLongitude = Convert.ToDouble(geoposition.Coordinate.Longitude.ToString("0.0000000000000"));

var geoQ = new ReverseGeocodeQuery();
geoQ.QueryCompleted += geoQ_QueryCompleted;

if (geoQ.IsBusy == true)
{
    geoQ.CancelAsync();
}
// Set the geo coordinate for the query

geoQ.GeoCoordinate = new GeoCoordinate(currentLocationLatitude, currentLocationLongitude);

geoQ.QueryAsync();

Thanks
