【中文标题】如何在 C# 中获取用户的国家/地区名称?【英文标题】:How do you get a user's country name in C#? 【发布时间】:2012-01-17 16:02:45 【问题描述】:我目前正在使用地理定位来获取用户的国家/地区名称。这是我的代码:
navigator.geolocation.getCurrentPosition(function (pos)
var latlng = pos.coords.latitude + "," + pos.coords.longitude;
var apiurl = 'http://maps.google.com/maps/geo?output=json&sensor=false&q=' + latlng;
var yqlqry = encodeURIComponent('select * from json where url="' + apiurl + '"');
var yqlurl = 'http://query.yahooapis.com/v1/public/yql?q=' + yqlqry + '&format=json&callback=?';
$.getJSON(yqlurl, function (data)
var countryName = data.query.results.json.Placemark.AddressDetails.Country.CountryName;
var newCountryName = countryName.toLowerCase();
if (newCountryName == "united states")
newCountryName = "us";
else if (newCountryName == "england" || newCountryName == "ireland" || newCountryName == "scotland" || newCountryName == "wales" || newCountryName == "northern ireland")
newCountryName = "uk";
else if (newCountryName == "australia")
newCountryName = "au";
else if (newCountryName == "canada")
newCountryName = "ca";
else
newCountryName = "world";
$('a[title = "' + newCountryName + '"]').trigger('click');
);
);
我宁愿在服务器端使用一些东西。有谁知道您是否可以在 C# 中获取用户的国家/地区名称?
【问题讨论】:
在 C# 中发出相同的请求 - 获取您从导航器的 GeoAPI 获得的位置并将其转发到服务器上您自己的 Web 服务,该服务器使用WebClient
类发出 Get 请求
我想向您指出,爱尔兰不在英国。北爱尔兰是,但爱尔兰是爱尔兰***,它本身就是一个国家。
【参考方案1】:
在服务器端,您唯一可以回复的是 IP 地址,您可以使用它来执行位置查找。那里有免费的 IP 地址到位置映射数据库,或者您可以使用 HostIP.info。

【参考方案2】:我为 WP7 做了这个,但代码在 standard.net 框架中几乎相同:http://www.felicepollano.com/2012/01/11/AnImplementationOfICivicAddressResolverForWP7.aspx 做这项工作的班级在下面。只需删除作为 WP7 依赖项的 ICIvicAddressResolver 并创建您自己的接口。
public class AddressResolver:ICivicAddressResolver
string language = "en-GB";
public AddressResolver()
public AddressResolver(string language)
this.language = language;
[DataContract]
public class AddressInfo
[DataMember(Name = "formatted_address")]
public string FormattedAddress get; set;
[DataContract]
public class ResultInfo
[DataMember(Name = "results")]
public AddressInfo[] Info get; set;
readonly string URITemplate = "http://maps.googleapis.com/maps/api/geocode/json?latlng=0,1&sensor=true&language=2";
#region ICivicAddressResolver Members
public CivicAddress ResolveAddress(GeoCoordinate coordinate)
throw new NotImplementedException("Use async version instead");
public void ResolveAddressAsync(GeoCoordinate coordinate)
WebClient client = new WebClient();
client.Encoding = Encoding.UTF8;
client.DownloadStringCompleted += (s, e) =>
if (e.Error == null)
var ainfo = ReadToObject<ResultInfo>(e.Result);
ResolveAddressCompleted(this, new ResolveAddressCompletedEventArgs(ToCivic(ainfo),e.Error,false,null));
else
ResolveAddressCompleted(this, new ResolveAddressCompletedEventArgs(new CivicAddress(), e.Error, false, null));
;
client.DownloadStringAsync(new Uri(GetFormattedUri(coordinate)));
private CivicAddress ToCivic(ResultInfo ainfo)
List<string> res = new List<string>();
foreach (var single in ainfo.Info)
res.Add(single.FormattedAddress);
if (res.Count > 0)
return new CivicAddress() AddressLine1 = res[0] ;
else
return new CivicAddress() AddressLine1 = "#UNKNOWN#" ;
public event EventHandler<ResolveAddressCompletedEventArgs> ResolveAddressCompleted = delegate ;
#endregion
private string GetFormattedUri(GeoCoordinate coord)
return string.Format(CultureInfo.InvariantCulture, URITemplate, coord.Latitude, coord.Longitude,language);
public static T ReadToObject<T>(string json) where T : class
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(json));
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
T res = ser.ReadObject(ms) as T;
ms.Close();
return res;

【参考方案3】:为什么不试试 IP2Location 的 API 呢?
你可以像这样传递你的IP地址。
http://api.ip2location.com/?ip=145.228.219.221&key=demo

【参考方案4】:不知道这是否有帮助,但在本地这个
CultureInfo.CurrentCulture.Name
根据您当前的语言环境返回类似“en-GB”或“fr-FR”的内容
