Answer 1

以下是您將從前面提到的註冊表項中檢索到的GeoID列表:(它們是十六進制的）

http://msdn.microsoft.com/en-us/library/dd374073%28VS.85%29.aspx

項：

HKEY_CURRENT_USER\Control Panel\International\Geo 

Answer 2

HKEY_CURRENT_USER \控制面板\國際\地理

我不知道，如何將數字轉換爲國家的名稱:(

Answer 3

有它返回選定位置的大地水準面的API函數：

GEOID locationId = GetUserGeoID(GEOCLASS_NATION); 

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

Answer 4

也許我們eful代碼（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; 


#region Win32 Declarations 

// [DllImport("kernel32.dll", ExactSpelling = true, CallingConvention = CallingConvention.StdCall, SetLastError = true)]

private string GetGeoFriendlyName(int geoId) 
{ 
    int lcid = GetUserDefaultLCID(); 
    StringBuilder bldr = new StringBuilder(50); 
    GetGeoInfo(geoId, GEO_FRIENDLYNAME, bldr, bldr.Capacity, lcid); 
    return bldr.ToString(); 
} 

private string GetGeoIso2(int geoId) 
{ 
    int lcid = GetUserDefaultLCID(); 
    StringBuilder bldr = new StringBuilder(50); 
    GetGeoInfo(geoId, GEO_ISO2, bldr, bldr.Capacity, lcid); 
    return bldr.ToString(); 
} 




    // HKEY_CURRENT_USER\Control Panel\International\Geo" 
    using (var regKeyGeo = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(@"Control Panel\International\Geo")) 
    { 
     var NationValue = Convert.ToInt32(regKeyGeo.GetValue("Nation").ToString()); 

     int geoId = GetUserGeoID(GEOCLASS_NATION); 
     string friendlyName = GetGeoFriendlyName(geoId); 
     Response.Write("GetUserGeoID: " + geoId + " - friendlyName: " + friendlyName + @". HKEY_CURRENT_USER\Control Panel\International\Geo - Nation: " + NationValue + " - " + GetGeoFriendlyName(NationValue));
