about dll libraries

Hi iswarya,
yes you can do it. its available in .net. but you can only get the Country.

ex:

in aspx code:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>





   


   

   

       
       
   

   

in .cs code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Globalization;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            DropDownList1.DataSource = CountryList();
            DropDownList1.DataBind();
        }
    }
    public static List CountryList()
    {
        //Creating list
        List CultureList = new List();
        //getting  the specific  CultureInfo from CultureInfo class
        CultureInfo[] getCultureInfo = CultureInfo.GetCultures(CultureTypes.SpecificCultures);
        foreach (CultureInfo getCulture in getCultureInfo)
        {
            //creating the object of RegionInfo class
            RegionInfo GetRegionInfo = new RegionInfo(getCulture.LCID);
            //adding each county Name into the arraylist
            if (!(CultureList.Contains(GetRegionInfo.EnglishName)))
            {
                CultureList.Add(GetRegionInfo.EnglishName);
            }
        }
        //sorting array by using sort method to get countries in order
        CultureList.Sort();
        //returning country list
        return CultureList;
    }

}
