Populate country dropdown of you Form automatically using C# code

Generally while working on Registration or submission form we need to populate all the country name dropdownlist, copying pasting is difficult task in the DropDownList. Below is the function that populates the DropDownList that is passed to this function.

You will need to use following namespaces

using System.Configuration;
using System.Globalization;

/// <summary>
        /// populate country name
        /// </summary>
        /// <param name="dropDown"></param>
        public static void GetCountryNames(DropDownList dropDown)
        {
            Hashtable h = new Hashtable();

            Dictionary<string, string> objDic = new Dictionary<string, string>();
            foreach (CultureInfo ObjCultureInfo in CultureInfo.GetCultures(CultureTypes.SpecificCultures))
            {
                RegionInfo objRegionInfo = new RegionInfo(ObjCultureInfo.Name);
                if (!objDic.ContainsKey(objRegionInfo.EnglishName))
                {
                    objDic.Add(objRegionInfo.EnglishName, objRegionInfo.TwoLetterISORegionName.ToLower());
                }
            }

            SortedList<string, string> sortedList = new SortedList<string, string>(objDic);

            foreach (KeyValuePair<string, string> val in sortedList)
            {
                dropDown.Items.Add(new ListItem(val.Key, val.Key));
            }

            dropDown.Items.Insert(0, new ListItem("Select", "Select"));
            dropDown.Items.Insert(1, new ListItem("Other Country", "Other"));
        }
    }

Call this function like this

PopulateCountryName(dropDownCountry);

Hope this will be helpful
