Problem: When I entry into Text1 like 20 or 20000 or 2000000 then show Taka only or Thousand Taka only or Lac Taka only respectively. But should show twenty or twenty thousand or twenty Lac respectively.

I am not able to answer your question because I do not really understand it perhaps because I lack knowledge about Bangladesh currency, but you would be better of if you replaced your convoluted (and also somewhat buggy) collection of if statements with a simple array of number words with 99 elements. — Martin Liversage, Jun 27 '13 at 20:27
To our Bangladeshi currency is like: 1=one taka, 10=ten taka, 100=one hundred taka, 1000=one thousand taka, 99000=ninety nine thousand taka, 100000= one lac taka, 1000000=ten lac taka, 10000000=one crore taka — Nur Muhammad, Jun 27 '13 at 20:32
I've been tasked with maintaining code like this before. For the sake of both your sanity and the sanity of your successors, please take the time to simplify this code. Once you do that, I think you'll find that your question is much easier to answer, as it will be a natural extension of the pattern you've used to simplify the original approach. — Dan Bryant, Jun 27 '13 at 20:37
I’m voting to close this question because this question would be a better fit for CodeReview. — Daniel Mann, Jan 23 '22 at 18:22

I'm not sure if this is exactly how you say it, but I'll give it a try:

//this array specifies the names of the powers of 10
static Tuple<int, string>[] powers =
{ 
    new Tuple<int, string>(0, ""),
    new Tuple<int, string>(3, "thousand"),
    new Tuple<int, string>(5, "lac"),
    new Tuple<int, string>(7, "crore")
};

//this array specifies the digits' names
static string[] digits = { "", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" };
static string[] extendedDigits = { "ten", "eleven", "twelve", "thirteen", "fourteen", "fivteen", "sixteen", "seventeen", "eighteen", "nineteen" };
static string[] tensWords = { "", "", "twenty", "thirty", "fourty", "fifty", "sixty", "seventy", "eighty", "ninety" };

private static string NumberToWords(long number)
{
    var sb = new StringBuilder();

    //begin with the left most digit (greatest power of 10)
    for (int i = powers.Length - 1; i >= 0; --i)
    {
        //translate the current part only (for a known power of 10)
        //usually part is a 3-digit number
        int part = (int)(number / (long)Math.Pow(10, powers[i].Item1)); 
        //if the part is 0, we don't have to add anything
        if (part > 0)
        {
            //extract the hundreds
            int hundreds = part / 100;
            if(hundreds > 9)
                throw new ArgumentException(number + " is too large and cannot be expressed.");
            if (hundreds > 0)
            {
                //if there are hundreds, copy them to the output
                sb.Append(digits[hundreds]);
                sb.Append(" hundred ");
            }
            //convert the next two digits
            sb.Append(TwoDigitNumberToWord(part % 100));
            sb.Append(" ");
            //and append the name of the power of 10
            sb.Append(powers[i].Item2);
            sb.Append(" ");
            //subtract the currently managed part
            number -= part * (long)Math.Pow(10, powers[i].Item1);
        }
    }
    return sb.ToString();
}

private static string TwoDigitNumberToWord(int number)
{
    //one digit case
    if (number < 10)
        return digits[number];
    //special case 10 <= n <= 19
    if (number < 20)
        return extendedDigits[number - 10];
    int tens = number / 10;
    int ones = number % 10;
    //concatenate the word from the two digits' words
    return tensWords[tens] + " " + digits[ones];

Throwing this into the wild (and ducking):

It prints out:

ten thousand
ten thousand one hundred
ten thousand one hundred and one
ninety nine thousand nine hundred ninety nine
one lac
one lac and one
ten lac
one crore
one crore and one

This may(?) answer your question. It appears you're trying to do the same thing, just in a much more convoluted way. converting numbers in to words C#
