//Code snippet
/// <summary>
/// method for generating a country list, say for populating
/// a ComboBox, with country options. We return the
/// values in a Generic List<t>
/// </t></summary>
/// <returns></returns>
public static List<string> GetCountryList()
{
    //create a new Generic list to hold the country names returned
    List<string> cultureList = new List<string>();

    //create an array of CultureInfo to hold all the cultures found, these include the users local cluture, and all the
    //cultures installed with the .Net Framework
    CultureInfo[] cultures = CultureInfo.GetCultures(CultureTypes.AllCultures & ~CultureTypes.NeutralCultures);

    //loop through all the cultures found
    foreach (CultureInfo culture in cultures)
    {
        //pass the current culture's Locale ID (http://msdn.microsoft.com/en-us/library/0h88fahh.aspx)
        //to the RegionInfo contructor to gain access to the information for that culture
        RegionInfo region = new RegionInfo(culture.LCID);

        //make sure out generic list doesnt already
        //contain this country
        if (!(cultureList.Contains(region.EnglishName)))
            //not there so add the EnglishName (http://msdn.microsoft.com/en-us/library/system.globalization.regioninfo.englishname.aspx)
            //value to our generic list
            cultureList.Add(region.EnglishName);
    }
    return cultureList;
}
