There are quite a lot of these 'number to words' methods around. This thread contains links to my own efforts which can deal with the US UK and Indian numbering systems: http://www.c-sharpcorner.com/Forums/Thread/185425/i-arrived-the-net-pay-amount-that-should-want-in-words-a.aspx To represent (for example) 45 as Four Five rather than Forty Five is relatively easy. Here's a method which does it: using System; class Program { static void Main() { int[] nums = {45 1097245 -156 -8945 0}; foreach(int num in nums) { Console.WriteLine({0} in words is {1} num NumToWords(num)); } Console.ReadKey(); } static string NumToWords(int num) { bool negative = (num if (negative) num = -num; string[] numbers = {Zero One Two Three Four Five Six Seven Eight Nine}; string numStr = num.ToString(); string[] words = new string[numStr.Length]; for(int i = 0; i string result = String.Join(  words); if (negative) result = Minus  + result; return result; } }

In this link( http://stackoverflow.com/questions/3213/convert-integers-to-written-numbers ) Check Wedge's answer. I have posted the same piece of code here. public static class HumanFriendlyInteger { static string[] ones = new string[] {  One Two Three Four Five Six Seven Eight Nine }; static string[] teens = new string[] { Ten Eleven Twelve Thirteen Fourteen Fifteen Sixteen Seventeen Eighteen Nineteen }; static string[] tens = new string[] { Twenty Thirty Forty Fifty Sixty Seventy Eighty Ninety }; static string[] thousandsGroups = {   Thousand  Million  Billion }; private static string FriendlyInteger(int n string leftDigits int thousands) { if (n == 0) { return leftDigits; } string friendlyInt = leftDigits; if (friendlyInt.Length > 0) { friendlyInt +=  ; } if (n { friendlyInt += ones[n]; } else if (n { friendlyInt += teens[n - 10]; } else if (n { friendlyInt += FriendlyInteger(n % 10 tens[n / 10 - 2] 0); } else if (n { friendlyInt += FriendlyInteger(n % 100 (ones[n / 100] +  Hundred) 0); } else { friendlyInt += FriendlyInteger(n % 1000 FriendlyInteger(n / 1000  thousands+1) 0); } return friendlyInt + thousandsGroups[thousands]; } public static string IntegerToWritten(int n) { if (n == 0) { return Zero; } else if (n { return Negative  + IntegerToWritten(-n); } return FriendlyInteger(n  0); } }
