На случай, если кто-то еще столкнется с этой проблемой, мне пришлось написать инструмент командной строки, чтобы отменить регистрацию культуры, а затем заново зарегистрировать ее.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Globalization;
namespace InstallCulture
{
class Program
{
static void Main(string[] args)
{
// Is CustomCulture already installed?
string parentCultureName = "en-GB";
string extendedName = "custom";
System.Globalization.CultureInfo[] userCultures = System.Globalization.CultureInfo.GetCultures(System.Globalization.CultureTypes.UserCustomCulture);
Console.WriteLine(string.Format("number of user cultures:{0}", userCultures.Count()));
Console.WriteLine(string.Format("Setting culture {0}-{1}", parentCultureName, extendedName));
// Install CustomCulture based on language parent.
System.Globalization.CultureAndRegionInfoBuilder builder = new System.Globalization.CultureAndRegionInfoBuilder(
string.Format("{0}-{1}", parentCultureName, extendedName),
System.Globalization.CultureAndRegionModifiers.None);
builder.LoadDataFromCultureInfo(new System.Globalization.CultureInfo("en-GB"));
builder.LoadDataFromRegionInfo(new System.Globalization.RegionInfo("GB"));
Console.WriteLine("CultureName:. . . . . . . . . . {0}", builder.CultureName);
Console.WriteLine("CultureEnglishName: . . . . . . {0}", builder.CultureEnglishName);
Console.WriteLine("CultureNativeName:. . . . . . . {0}", builder.CultureNativeName);
foreach(System.Globalization.CultureInfo cultInfo in userCultures)
{
Console.WriteLine("Found culture in userCultures");
if(cultInfo.Name.ToLower() == string.Format("{0}-{1}", parentCultureName, extendedName).ToLower())
{
Console.WriteLine(string.Format("{0} already registered", cultInfo.Name));
CultureAndRegionInfoBuilder.Unregister("en-GB-custom");
Console.WriteLine("Unregistered culture en-GB-custom");
}
}
Console.WriteLine("Registering culture en-GB-PolHol");
builder.Register();
Console.WriteLine("Create new culture info object");
System.Globalization.CultureInfo culture = new System.Globalization.CultureInfo("en-GB-custom");
Console.WriteLine("Name: . . . . . . . . . . . . . {0}", culture.Name);
Console.WriteLine("EnglishName:. . . . . . . . . . {0}", culture.EnglishName);
Console.WriteLine("NativeName: . . . . . . . . . . {0}", culture.NativeName);
Console.WriteLine("Set threads to new culture");
System.Threading.Thread.CurrentThread.CurrentCulture = culture;
System.Threading.Thread.CurrentThread.CurrentUICulture = culture;
Console.WriteLine("Set culture done");
}
}
}
