How to create custom helper for converting Number to word

Raju Fodse

I am developing web app using I want to display currency amount in word and I want to use custome HTML helper. How can I call function in HTML Helper.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace EasyApp.Models
{
public static class NWConverter
{
public static IHtmlString Retrieve_Label(this HtmlHelper helper)
{
//I want use this html helper
}
public string Rupees(Int32 rup)
{
string result = "";
Int32 res;
if ((rup / 10000000) > 0)
{
res = rup / 10000000;
rup = rup % 10000000;
result = result + ' ' + RupeesToWords(res) + " Crore";
}
if ((rup / 100000) > 0)
{
res = rup / 100000;
rup = rup % 100000;
result = result + ' ' + RupeesToWords(res) + " Lack";
}
if ((rup / 1000) > 0)
{
res = rup / 1000;
rup = rup % 1000;
result = result + ' ' + RupeesToWords(res) + " Thousand";
}

res = rup / 100;
rup = rup % 100;
result = result + ' ' + RupeesToWords(res) + " Hundred";
}
if ((rup % 10) >= 0)

This is, how you can create custom helper in your scenario.
public static class NumberToWord
   {
       public static MvcHtmlString Rupees(this HtmlHelper html, double rupeesInNumber)
       {
           string value = ConvertAmount(rupeesInNumber);
           return MvcHtmlString.Create(value);

       }

       private static String[] units = { "Zero", "One", "Two", "Three",
   "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven",
   "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen",
   "Seventeen", "Eighteen", "Nineteen" };
       private static String[] tens = { "", "", "Twenty", "Thirty", "Forty",
   "Fifty", "Sixty", "Seventy", "Eighty", "Ninety" };

       public static String ConvertAmount(double amount)
       {
           try
           {
               Int64 amount_int = (Int64)amount;
               Int64 amount_dec = (Int64)Math.Round((amount - (double)(amount_int)) * 100);
               if (amount_dec == 0)
               {
                   return Convert(amount_int) + " Only.";

Before implementing it for the function, we first must know what is that function made for?
