http://maps.googleapis.com/maps/api/geocode/json?address="; +
(System.Web.HttpUtility.UrlEncode(address) + "&sensor=false
I use this URL, and pass in JUST the ZIP code, w/o any kind of Google API
authentication token, just using this URL. Go to this URL in Chrome, and
then replace the (system.web.xxxxxxx) with your ZipCode. Include the
sensor=false in the URL string.
This returns a JSON object. I parse it out and get the location lat and long
from it. Get a web response and then pull it out of the response string. My
"oController" code saves the geo coords into a database for use later.

string str = null;
using (Stream stream = response.GetResponseStream())
{
using (StreamReader streamReader = new
StreamReader(stream))
{
str = streamReader.ReadToEnd();
}
}
GeoResponse geoResponse =
JsonConvert.DeserializeObject<GeoResponse>(str);
if (geoResponse.Status == "OK")
{
int count = geoResponse.Results.Length;
for (int i = 0; i < count; i++)
{
this.ScheduleHistoryItem.AddLogNote("BusinessID:
" + BusinessID + ".<br />");
this.ScheduleHistoryItem.AddLogNote("latitude: "
+ geoResponse.Results[i].Geometry.Location.Lat.ToString() + ".<br />");
this.ScheduleHistoryItem.AddLogNote("longitude:
" + geoResponse.Results[i].Geometry.Location.Lng.ToString() + ".<br />");
// update the database with the Geo Coord from
Google Maps API
oController.UpdateProspectGeoCoordsinDB(BusinessID,
geoResponse.Results[i].Geometry.Location.Lat.ToString(),
geoResponse.Results[i].Geometry.Location.Lng.ToString());
i = count;
}
}
