有没有一种简单的方法可以将数字转换为带有十万和十万字的印度文字格式？

Question

如标题所示，我想使用C＃将长整数转换为带有单词的格式。文化设置似乎没有执行此操作，而我目前正在执行此操作

String.Format(new CultureInfo("en-IN"), "{0:C0}", Price)

但是对于很长的数字，我希望使用单词格式。我不是来自印度，只是模糊地熟悉该系统的工作原理。

public static string NumberToWords(int number)
    {
        if (number == 0) { return "zero"; }
        if (number < 0) { return "minus " + NumberToWords(Math.Abs(number)); }
        string words = "";
        if ((number / 10000000) > 0) { words += NumberToWords(number / 10000000) + " Crore "; number %= 10000000; }
        if ((number / 100000) > 0) { words += NumberToWords(number / 100000) + " Lakh "; number %= 100000; }
        if ((number / 1000) > 0) { words += NumberToWords(number / 1000) + " Thousand "; number %= 1000; }
        if ((number / 100) > 0) { words += NumberToWords(number / 100) + " Hundred "; number %= 100; }
        if (number > 0)
        {
            if (words != "") { words += "and "; }
            var unitsMap = new[] { "Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven", "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen", "Seventeen", "Eighteen", "Nineteen" };
            var tensMap = new[] { "Zero", "Ten", "Twenty", "Thirty", "Forty", "Fifty", "Sixty", "seventy", "Eighty", "Ninety" };
            if (number < 20) { words += unitsMap[number]; }
            else { words += tensMap[number / 10]; if ((number % 10) > 0) { words += "-" + unitsMap[number % 10]; } }
        }
        return words;
    }
