I have used to get latitude & longitude by using google Geo-coding API
but while send a request i got this error can you help me to how resolve
this issue?
*code : *
string fullAddress = string.Empty;
if (!string.IsNullOrEmpty(address) || zipCode != null)
{
fullAddress = string.Format("{0} {1}", address.Trim().Replace('
', '+'), zipCode);
}
*string url =
"https://maps.googleapis.com/maps/api/geocode/json?address={0}&sensor=true&key={1}";;
* //Map.GetMapGeoLocationV2(fullAddress);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.KeepAlive = false;
request.ProtocolVersion = HttpVersion.Version10;
request.Credentials = System.Net.CredentialCache.DefaultCredentials;
request.UseDefaultCredentials = true;
request.ConnectionGroupName = Guid.NewGuid().ToString();
// ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
request.Method = "GET";
// var response = request.GetResponse();
try
{
HttpWebResponse response =
(HttpWebResponse)request.GetResponse();
System.Threading.Thread.Sleep(1000);
using (var stream = response.GetResponseStream())
{
using (var reader = new StreamReader(stream))
{
var result =
Newtonsoft.Json.Linq.JObject.Parse(reader.ReadToEnd());
outstatus = result.SelectToken("status").ToString() !=
null ? result.SelectToken("status").ToString() : string.Empty;
if (outstatus == "OK")
{
latitude =
result.SelectToken("results[0].geometry.location.lat").ToString() != null ?
result.SelectToken("results[0].geometry.location.lat").ToString() :
string.Empty;
longitude =
result.SelectToken("results[0].geometry.location.lng").ToString() != null ?
result.SelectToken("results[0].geometry.location.lng").ToString() :
string.Empty;
var addresscomponentsCount =
result.SelectToken("results[0].address_components").Count();
for (int i = 0; i < addresscomponentsCount; i++)
{
var addresscomponentsTypesCount =
result.SelectToken("results[0]." + string.Format("address_components[" +
"{0}" + "]", i) + ".types").Count();
for (int j = 0; j <
addresscomponentsTypesCount; j++)
{
var type = result.SelectToken("results[0]."
+ string.Format("address_components[" + "{0}" + "]", i) +
string.Format(".types[" + "{0}" + "]", j)).ToString();
if (type == "administrative_area_level_1")
{
state =
result.SelectToken("results[0]." + string.Format("address_components[" +
"{0}" + "]", i) + ".short_name").ToString();
}
if (type == "postal_code")
{
outZipCode =
result.SelectToken("results[0]." + string.Format("address_components[" +
"{0}" + "]", i) + ".short_name").ToString();
}
}
}
response.Close();
}
reader.Close();
}
stream.Close();
}
}
