how to parse a Google Maps geocoding result
You can check for 3 variables in the google response (json) to find the current cityname. Hence there is 3 different interpretation of the name:
Country |AdministrativeArea | |_AdministrativeAreaName (cityname) | |_Locality_LocalityName (cityname) | |_SubAdministrativeArea | |_Locality_LocalityName (cityname)if ($this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->Locality->LocalityName != NULL) { $code['cityname'] = $this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->Locality->LocalityName;} elseif ($this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->SubAdministrativeArea->Locality->LocalityName != NULL) { $code['cityname'] = $this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->SubAdministrativeArea->Locality->LocalityName;} If you have more then a Placemark you need to loop through all the array.

I have a simple solution that works for the Google Geocode JSON results. It is a simple for loop that returns that short and long version in a string array. Just call the function and provide the "types" in the argument.
string[] street_number = GetJSONValueBasedOnType(record.geocode, "street_number");
public string[] GetJSONValueBasedOnType(NewGoogleGeocode gc, string WhatYouWant){ string[] returns = new string[2]; returns[0] = string.Empty; returns[1] = string.Empty; bool isInIt; foreach (var v in gc.results[0].address_components) { isInIt = false; foreach (var t in v.types) { if (t == WhatYouWant) { isInIt = true; } } if (isInIt) { returns[0] = v.short_name; returns[1] = v.long_name; } } return returns;}
