アプリケーションでデバイスの地域を取得するにはどうしたらいいか?

Windows Phone の言語と地域にはいくつかの設定があり、それぞれは異なる意味を持つ

  • 電話の言語:表示言語
  • 国/地域:国の設定だがMarketplaceの地域は Windows Account に紐づいているのでこれとは関係ない。尚これを設定するとある程度自動的に下の「地域設定」も連動して変更される(地域設定だけ別途変更可能)
  • 地域設定:実際に使用している地域や、日付や時間、通貨の表示設定
  • ブラウザーと検索に使用する言語:文字通りブラウザの検索に使用する言語

そして上記設定の値をアプリケーションから取得するAPIはこちら

  • 電話の言語:System.Globalization.CultureInfo.CurrentUICulture
  • 国/地域:たぶんなし
  • 地域設定:System.Globalization.RegionInfo.CurrentRegion, System.Globalization.CultureInfo.CurrentCulture
  • ブラウザーと検索に使用する言語:たぶんなし

見てわかる通り、結局あくまでもユーザーが設定するもので、実際にそこにいるという保証はないもの。本当に実際の一がほしいのであればGPSの位置情報をもとに取得するしかない。

Google Map のこんなWeb サービスもある。

http://maps.googleapis.com/maps/api/geocode/json?latlng=latitiude,longitude&sensor=true

こんな感じ。

http://maps.googleapis.com/maps/api/geocode/json?latlng=35.6266,139.7404&sensor=true

JSONで戻り値をもらえる。
