在 C# 中是否有将城市名称转换为其时区名称(东京 --> 东京标准时间)的方法? [英] In C# is there anyway to convert a city name to its TimeZone name (Tokyo --> Tokyo Standard Time)?

问题描述

我有一个城市列表(纽约、伦敦等.)，我需要进行一些时区转换，但我看到大多数 API 要求您知道时区名称(例如东部标准时间、东京标准时间等).

无论如何可以将城市名称转换为其适当的时区名称?(在纽约传递，返回东部标准时间")

解决方案

不知道 C# 中内置了类似的东西，但您可以使用 Google Maps API:

1) 获取城市的经纬度:http://maps.googleapis.com/maps/api/geocode/json?address=New%20York,%20CA&sensor=false

2) 现在使用那些 long/lat 来获取时区:https://maps.googleapis.com/maps/api/timezone/json?location=43.2994285,-74.21793260000001&timestamp=1362209227&sensor=false>

示例代码:

 public TimeZoneResponse ConvertCityToTimeZoneName(string location){TimeZoneResponse 响应 = new TimeZoneResponse();var plusName = location.Replace(" ", "+");var address = "http://maps.google.com/maps/api/geocode/json?address=" + plusName + "&sensor=false";var result = new System.Net.WebClient().DownloadString(address);var latLongResult = JsonConvert.DeserializeObject<GoogleGeoCodeResponse>(result);if (latLongResult.status == "OK"){var timeZoneRespontimeZoneRequest = "https://maps.googleapis.com/maps/api/timezone/json?location=" + latLongResult.results[0].geometry.location.lat + "," + latLongResult.results[0].geometry.location.lng + "&timestamp=1362209227&sensor=false";var timeZoneResponseString = new System.Net.WebClient().DownloadString(timeZoneRespontimeZoneRequest);var timeZoneResult = JsonConvert.DeserializeObject(timeZoneResponseString);if (timeZoneResult.status == "OK"){response.TimeZoneName = timeZoneResult.timeZoneName;response.Success = true;返回响应；}}返回响应；}

I have a list of cities (New York, London, etc . .) and I need to do some timezone conversion but i see most of the APIs require that you know the time zone name (such as Eastern Standard Time, Tokyo Standard Time, etc).

Is there anyway to convert the city name into its appropriate TimeZone name ? (pass in New York and it returns "Eastern Standard Time")

解决方案

Not aware of anything like that built into C# but you can use Google Maps API for that:

1) Get the long/lat of the city: http://maps.googleapis.com/maps/api/geocode/json?address=New%20York,%20CA&sensor=false

2) Now use those long/lat to get the timezone: https://maps.googleapis.com/maps/api/timezone/json?location=43.2994285,-74.21793260000001&timestamp=1362209227&sensor=false

Example Code:

   public TimeZoneResponse ConvertCityToTimeZoneName(string location)
   {
       TimeZoneResponse response = new TimeZoneResponse();
       var plusName = location.Replace(" ", "+");
       var address = "http://maps.google.com/maps/api/geocode/json?address=" + plusName + "&sensor=false";
       var result = new System.Net.WebClient().DownloadString(address);
       var latLongResult = JsonConvert.DeserializeObject<GoogleGeoCodeResponse>(result);

       if (latLongResult.status == "OK")
       {
           var timeZoneRespontimeZoneRequest = "https://maps.googleapis.com/maps/api/timezone/json?location=" + latLongResult.results[0].geometry.location.lat + "," + latLongResult.results[0].geometry.location.lng + "&timestamp=1362209227&sensor=false";
           var timeZoneResponseString = new System.Net.WebClient().DownloadString(timeZoneRespontimeZoneRequest);
           var timeZoneResult = JsonConvert.DeserializeObject<TimeZoneResult>(timeZoneResponseString);

           if (timeZoneResult.status == "OK")
           {

               response.TimeZoneName = timeZoneResult.timeZoneName;
               response.Success = true;
               return response;
           }
       }
       return response;
   }
