【问题讨论】：

标签： windows winapi windows-7 windows-vista windows-xp

【解决方案1】：

HKEY_CURRENT_USER\控制面板\国际\地理

我不知道，如何将数字转换为国家名称:(

【讨论】：

看这里有一个号码列表和对应的国家msdn.microsoft.com/en-us/library/dd374073%28VS.85%29.aspx

【解决方案2】：

这是您将从前面提到的注册表项中检索到的 GeoID 列表：（它们是十六进制的）

条目：

HKEY_CURRENT_USER\Control Panel\International\Geo

【讨论】：

【解决方案3】：

有一个 API 函数可以返回所选位置的 GEOID：

GEOID locationId = GetUserGeoID(GEOCLASS_NATION);

见http://msdn.microsoft.com/en-us/library/dd318138(v=VS.85).aspx

也许有用的代码（C#）

private const int GEOCLASS_NATION = 16;

//SYSGEOTYPE
private const int GEO_NATION = 1;
private const int GEO_LATITUDE = 2;
private const int GEO_LONGITUDE = 3;
private const int GEO_ISO2 = 4;
private const int GEO_ISO3 = 5;
private const int GEO_RFC1766 = 6;
private const int GEO_LCID = 7;
private const int GEO_FRIENDLYNAME = 8;
private const int GEO_OFFICIALNAME = 9;
private const int GEO_TIMEZONES = 10;
private const int GEO_OFFICIALLANGUAGES = 11;

真的，我用[DllImport("kernel32.dll")] static extern int GetUserGeoID(int geoId);
