Convert Current Date into Words format by Creating a Class in C# ASP.NET

Some times we face the problem if we want to convert the date format in to words then we have many options to do this task, i will give the answer using C# Class. 

Solution :-
For example : we get the date in c# with code (DateTime.Today) and convert it in words.
First Create a Class with Name class  'DateInWords' and Code Like this :-
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

public static class DateInWords
{
    static int firstTime = 0;
    static readonly string[] ones = new string[] { "", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine" };
    static readonly string[] firsts = new string[] { "", "First", "Second", "Third", "Fourth", "Fifth", "Sixth", "Seventh", "Eighth", "Ninth" };
    static readonly string[] teens = new string[] { "Ten", "Eleven", "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen", "Seventeen", "Eighteen", "Nineteen" };
    static readonly string[] tens = new string[] { "Twenty", "Thirty", "Forty", "Fifty", "Sixty", "Seventy", "Eighty", "Ninety" };
    static readonly string[] thousandsGroups = { "", " Thousand", " Million", " Billion" };

    private static string FriendlyInteger(int n, string leftDigits, int thousands)
    {
        if (n == 0)
        {
            return leftDigits;
        }
        else
        {
            string friendlyInt = leftDigits;
            if (friendlyInt.Length > 0)
                friendlyInt += " ";

            if (n < 10 & firstTime == 0)
            {
                friendlyInt += firsts[n];
            }
            else if (n < 10 & firstTime != 0)
            {
                friendlyInt += ones[n];
            }
            else if (n < 20)
                friendlyInt += teens[n - 10];
            else if (n < 100)
                friendlyInt += FriendlyInteger(n % 10, tens[n / 10 - 2], 0);
            else if (n < 1000)
                friendlyInt += FriendlyInteger(n % 100, (firsts[n / 100] + " Hundred"), 0);
            else
                friendlyInt += FriendlyInteger(n % 1000, FriendlyInteger(n / 1000, "", thousands + 1), 0);

            firstTime = firstTime + 1;
            return friendlyInt + thousandsGroups[thousands];
        }
    }

    public static string DateToWritten(DateTime date)
    {
        firstTime = 0;
        return string.Format("{0} {1} {2}", IntegerToWritten(date.Day), date.ToString("MMMM"), IntegerToWritten(date.Year));
    }

    public static string IntegerToWritten(int n)
    {
        if (n == 0)
            return "Zero";
        else if (n < 0)
            return "Negative " + IntegerToWritten(-n);

        return FriendlyInteger(n, "", 0);
    }
}
and this class will return the date format in word .. So firstly we must pass the parameter in this class with any date format given in standards ... Example :
var outputDate = DateInWords.DateToWritten(DateTime.Today);// Current date is passing in DateToWritten function of 'DateInWords' static class.
        dateLabel.Text = outputDate;
the output will display in 'dateLabel'





That’s it!!…..Happy Programming...
