Cla*_*pel 3 c# country culture locale region
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(参见屏幕截图),但我无法获取返回德国的代码。重新启动计算机没有帮助。
我受此线程启发编写了一些代码。
我的代码如下所示(同时尝试各种事情,获取我能想到的所有地区/文化事物):
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

我怎样才能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?
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,正如@SanjaySingh 在该线程中所提议的那样,并且仅进行了轻微修改。
如果我调用GetMachineCurrentLocation参数geoFriendlyname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")。
的值可以在此处geoFriendlyname找到。
