How to create custom helper for converting Number to word

Question

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 = "" ;

result = result + ' ' + RupeesToWords(res) + " Lack" ; } if ((rup / 1000) > 0) { res = rup / 1000; rup = rup % 1000; result = result + ' ' + RupeesToWords(res) + " Thousand" ; } if ((rup / 100) > 0) { res = rup / 100;

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." ; } else { return Convert(amount_int) + " Point " + Convert(amount_dec) + " Only." ; } } catch (Exception e) { // TODO: handle exception } return "" ; } public static String Convert(Int64 i) { if (i { return units[i]; } if (i { return tens[i / 10] + ((i % 10 > 0) ? " " + Convert(i % 10) : "" ); } if (i { return units[i / 100] + " Hundred" + ((i % 100 > 0) ? " And " + Convert(i % 100) : "" ); } if (i { return Convert(i / 1000) + " Thousand " + ((i % 1000 > 0) ? " " + Convert(i % 1000) : "" ); } if (i { return Convert(i / 100000) + " Lakh " + ((i % 100000 > 0) ? " " + Convert(i % 100000) : "" ); } if (i { return Convert(i / 10000000) + " Crore " + ((i % 10000000 > 0) ?

Before implementing it for the function, we first must know what is that function made for? public static IHtmlString Retrieve_Label(this HtmlHelper helper)
