在C#中,如何获取Windows 10中“区域和语言”下选择的“国家或地区”?

问题描述 投票:0回答:5

我运行的是 Windows 10。当我从开始菜单中打开“区域和语言设置”时,我可以选择“国家或地区”。我正在尝试在 C# 程序中获取该值。

我在丹麦。我尝试将我的国家/地区更改为德国(请参阅screenshot),但我无法获取返回德国的代码。重新启动计算机没有帮助。

我编写了一些受此线程启发的代码。

我的代码看起来像这样(一次尝试各种事情,得到我能想到的所有地区/文化的东西):

private static void Main(string[] args)
{
    Thread.CurrentThread.CurrentCulture.ClearCachedData();
    Thread.CurrentThread.CurrentUICulture.ClearCachedData();
    var thread = new Thread(() => ((Action) (() =>
    {
        Console.WriteLine("Current culture: {0}", Thread.CurrentThread.CurrentCulture.Name);
        Console.WriteLine("Current UI culture: {0}", Thread.CurrentThread.CurrentUICulture.Name);
        Console.WriteLine("Installed UI culture: {0}", CultureInfo.InstalledUICulture.Name);
        Console.WriteLine("Current region: {0}", RegionInfo.CurrentRegion.ThreeLetterISORegionName);
        Console.WriteLine("System default LCID: {0}", GetSystemDefaultLCID());
    }))());
    thread.Start();
    thread.Join();
    Console.ReadKey();
}

[DllImport("kernel32.dll")]
private static extern uint GetSystemDefaultLCID();

它输出:

Current culture: en-DK
Current UI culture: en-US
Installed UI culture: en-US
Current region: DNK
System default LCID: 1033

如何让我的程序检测到我选择了德国?我需要调用什么方法或属性?可能需要什么重新启动或清除缓存?

c# locale culture region country

我在这个帖子中找到了我的问题的答案。

我正在使用下面的代码,由 @SanjaySingh 在该线程中提出,仅稍加修改。

如果我调用

GetMachineCurrentLocation
并将
geoFriendlyname
参数设置为
5
,我会得到我想要的三个字母的 ISO 区域代码(对于德国,这是
"DEU"
)。

geoFriendlyname
的值可以在这里找到。

public static class RegionAndLanguageHelper
{
    #region Constants

    private const int GEO_FRIENDLYNAME = 8;

    #endregion

    #region Private Enums

    private enum GeoClass : int
    {
        Nation = 16,
        Region = 14,
    };

    #endregion

    #region Win32 Declarations

    [DllImport("kernel32.dll", ExactSpelling = true, CallingConvention = CallingConvention.StdCall, SetLastError = true)]
    private static extern int GetUserGeoID(GeoClass geoClass);

    [DllImport("kernel32.dll")]
    private static extern int GetUserDefaultLCID();

    [DllImport("kernel32.dll")]
    private static extern int GetGeoInfo(int geoid, int geoType, StringBuilder lpGeoData, int cchData, int langid);

    #endregion

    #region Public Methods

    /// <summary>
    /// Returns machine current location as specified in Region and Language settings.
    /// </summary>
    /// <param name="geoFriendlyname"></param>
    public static string GetMachineCurrentLocation(int geoFriendlyname)
    {
        int geoId = GetUserGeoID(GeoClass.Nation); ;
        int lcid = GetUserDefaultLCID();
        StringBuilder locationBuffer = new StringBuilder(100);
        GetGeoInfo(geoId, geoFriendlyname, locationBuffer, locationBuffer.Capacity, lcid);

        return locationBuffer.ToString().Trim();
    }

    #endregion
}

阅读 msdn 文档:RegionInfo Properties

var regionInfo = RegionInfo.CurrentRegion;
var name = regionInfo.Name;
var englishName = regionInfo.EnglishName;
var displayName = regionInfo.DisplayName;

Console.WriteLine("Name: {0}", name);
Console.WriteLine("EnglishName: {0}", englishName);
Console.WriteLine("DisplayName: {0}", displayName);   

名称:DE
英文名称: 德国
显示名称:德国

比所选答案短得多,并且不需要 DllImports 或 ClearCachedData:

var regKeyGeoId = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(@"Control Panel\International\Geo");
var geoID = (string)regKeyGeoId.GetValue("Nation");
var allRegions = CultureInfo.GetCultures(CultureTypes.SpecificCultures).Select(x => new RegionInfo(x.ToString()));
var regionInfo = allRegions.FirstOrDefault(r => r.GeoId == Int32.Parse(geoID));
Console.WriteLine("EnglishName:" + regionInfo.EnglishName);
Console.WriteLine("DisplayName:" + regionInfo.DisplayName);
Console.WriteLine("NativeName:" + regionInfo.NativeName);
Console.WriteLine("ISOCurrencySymbol:" + regionInfo.ISOCurrencySymbol);
Console.WriteLine("Name:" + regionInfo.Name);

这将读取您在 Windows 10 中“区域和语言”>“国家或地区”下设置的信息。

感谢@Zan,因为我的只是他帖子的延伸:在 C# 中获取当前位置(如区域和语言中指定)

如果您使用 GoogleMaps,则它是 ISO-3166 RegionInfo.CurrentRegion.TwoLetterISORegionName

尝试

    var geographicRegion = new Windows.Globalization.GeographicRegion();
    var code = geographicRegion.CodeTwoLetter;

    var region = Windows.System.UserProfile.GlobalizationPreferences.HomeGeographicRegion;
