Here's a method I wrote a while back which should do what you want. I've placed it inside a console app for testing purposes. Notice that it optionally supports UK style number/word translation i.e. One Hundred and Twenty Four as opposed to One Hundred Twenty Four. However, it doesn't support numbers with decimal points. using System; class Program { static void Main() { string input; int number; bool isValid; bool isUK = false; Console.WriteLine("
Enter '0' to quit the program at any time
"); while(true) { Console.Write("
Use UK numbering y/n : "); input = Console.ReadLine(); if (!(input.ToLower() == "y" || input.ToLower() == "n")) Console.WriteLine("
 Must be 'y' or 'n', please try again
"); else { if(input.ToLower() == "y") isUK = true; Console.WriteLine("
"); break; } } do { Console.Write("Enter integer : "); input = Console.ReadLine(); isValid = int.TryParse(input, out number); if(!isValid) Console.WriteLine("
 Not an integer, please try again
"); else Console.WriteLine("
 {0}
", NumberToText(number, isUK)); } while(!(isValid && number == 0)); Console.WriteLine("
Program ended"); } public static string NumberToText(int number, bool isUK) { if (number == 0) return "Zero"; string and = isUK ? "and " : ""; // deals with UK or US numbering if (number == -2147483648) return "Minus Two Billion One Hundred "+ and + "Forty Seven Million Four Hundred " + and + "Eighty Three Thousand " + "Six Hundred " + and + "Forty Eight"; int[] num = new int[4]; int first = 0; int u, h, t; System.Text.StringBuilder sb = new System.Text.StringBuilder(); if (number { sb.Append("Minus "); number = -number; } string[] words0 = {"" ,"One ", "Two ", "Three ", "Four ", "Five " ,"Six ", "Seven ", "Eight ", "Nine "}; string[] words1 = {"Ten ", "Eleven ", "Twelve ", "Thirteen ", "Fourteen ", "Fifteen ","Sixteen ","Seventeen ","Eighteen ", "Nineteen "}; string[] words2 = {"Twenty ", "Thirty ", "Forty ", "Fifty ", "Sixty ", "Seventy ","Eighty ", "Ninety "}; string[] words3 = {"Thousand ", "Million ","Billion "}; num[0] = number % 1000; // units num[1] = number / 1000; num[2] = number / 1000000; num[1] = num[1] - 1000 * num[2]; // thousands num[3] = number / 1000000000; // billions num[2] = num[2] - 1000 * num[3]; // millions for(int i = 3; i > 0 ; i--) { if (num[i] != 0) { first = i; break; } } for(int i = first ; i >= 0 ; i--) { if (num[i] == 0) continue; u = num[i] % 10; // ones t = num[i] / 10; h = num[i] / 100; // hundreds t = t - 10 * h; // tens if (h > 0) sb.Append(words0[h] + "Hundred "); if (u > 0 || t > 0) { if (h > 0 || i if (t == 0) sb.Append(words0[u]); else if (t == 1) sb.Append(words1[u]); else sb.Append(words2[t-2] + words0[u]); } if (i != 0) sb.Append(words3[i-1]); } return sb.ToString().TrimEnd(); } } // end class
