You can make use of a web service provided by Microsoft that returns the city, state and country based on the latitude and longitude you provide.

Create a web service reference in your project by providing the link http://msrmaps.com/TerraService2.asmx

I have named the service as myTerraService

myTerraService.TerraServiceSoapClient client = new myTerraService.TerraServiceSoapClient();
        client.ConvertLonLatPtToNearestPlaceCompleted += new EventHandler<myTerraService.ConvertLonLatPtToNearestPlaceCompletedEventArgs>(client_ConvertLonLatPtToNearestPlaceCompleted);
        client.ConvertLonLatPtToNearestPlaceAsync(new myTerraService.LonLatPt { Lat = latitude, Lon = longitude });
    }

    void client_ConvertLonLatPtToNearestPlaceCompleted(object sender, myTerraService.ConvertLonLatPtToNearestPlaceCompletedEventArgs e)
    {
        string location = e.Result; // this string will have city, state, country
    }

Yes, you can do this via the Bing Maps REST API, you need to perform a reverse geocode. This is done by GET-ing the following request:

http://dev.virtualearth.net/REST/v1/Locations/47.64054,-122.12934?o=xml&key=BingMapsKey

Which will return the address in XML format:
