Tengo el siguiente código C #. Por razones que no voy a entrar, esta es la forma requerida de localización.

Mi problema es que, por mi vida, no puedo averiguar qué camino no está devolviendo un valor. No hay otros errores en el siguiente código:

ResourceManager ResMain = new ResourceManager("TorrentSched.Main", typeof(Main).Assembly);
/// <summary>Returns a localised string based on the Current UI Culture</summary>
public string Str(string Name)
{
    Boolean StringNotFound = false;
    switch(Thread.CurrentThread.CurrentUICulture.ToString())
    {
        case "en-GB":
            switch(Name)
            {
                case "MinimizeToTray": return "Closing the program minimises it to the tray. To fully quit the program, right-click the icon in your tray and choose Exit.";
                default: StringNotFound = true; break;
            }
        break;
        default:
            StringNotFound = true;
        break;
    }

    if(StringNotFound)
    {
        StringNotFound = false;
        switch(Name)
        {
            case "AppName":         return ResMain.GetString("$this.Text");
            case "MinimizeToTray":  return "Closing the program minimizes it to the tray. To fully quit the program, right-click the icon in your tray and choose Exit.";
            case "ReallyExit1":     return "Do you really want to exit?";
            case "ReallyExit2":     return "Torrents will not be checked and downloaded until you launch the program again!";
            default:                return "String not found!";
        }
    }
}
