See this short post for C#. I briefly tested it and it works very well:

You just need to copy the two functions to your code to use it:

C#

static String NumWordsWrapper(double n)
      {
         string words = "";
         double intPart;
         double decPart = 0;
         if (n == 0)
            return "zero";
         try
         {
            string[] splitter = n.ToString().Split('.');
            intPart = double.Parse(splitter[0]);
            decPart = double.Parse(splitter[1]);
         }
         catch
         {
            intPart = n;
         }

         words = NumWords(intPart);

         if (decPart > 0)
         {
            if (words != "")
               words += " and ";
            int counter = decPart.ToString().Length;
            switch (counter)
            {
               case 1: words += NumWords(decPart) + " tenths"; break;
               case 2: words += NumWords(decPart) + " hundredths"; break;
               case 3: words += NumWords(decPart) + " thousandths"; break;
               case 4: words += NumWords(decPart) + " ten-thousandths"; break;
               case 5: words += NumWords(decPart) + " hundred-thousandths"; break;
               case 6: words += NumWords(decPart) + " millionths"; break;
               case 7: words += NumWords(decPart) + " ten-millionths"; break;
            }
         }
         return words;
      }

      static String NumWords(double n) //converts double to words
      {
         string[] numbersArr = new string[] { "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" };

         string words = "";

         bool tens = false;

hiii,

Define Object as

AmountInWords obj=new AmountInWords();
obj.ConvertAmount(100)

And Output is= One Hundred

where

AmountInWords.cs

C#

class AmountInWords
   {
       private static String[] units = { "Zero", "One", "Two", "Three",
           "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven",
           "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen",
           "Seventeen", "Eighteen", "Nineteen" };
       private static String[] tens = { "", "", "Twenty", "Thirty", "Forty",
           "Fifty", "Sixty", "Seventy", "Eighty", "Ninety" };


       public String ConvertAmount(double amount)
       {
           try
           {
               int amount_int = (int)amount;
               int amount_dec = (int)Math.Round((amount - (double)(amount_int)) * 100);
               return convert(amount_int) + "  point "
                       + convert(amount_dec);
           }
           catch (Exception e)
           {
               // TODO: handle exception
           }
           return "";
       }

       public String convert(int i)
       {
           //
           if (i < 20)
               return units[i];
           if (i < 100)
               return tens[i / 10] + ((i % 10 > 0) ? " " + convert(i % 10) : "");
           if (i < 1000)
               return units[i / 100] + " Hundred"
                       + ((i % 100 > 0) ? " and " + convert(i % 100) : "");
           if (i < 100000)
               return convert(i / 1000) + " Thousand "
                       + ((i % 1000 > 0) ? " " + convert(i % 1000) : "");
           if (i < 10000000)
               return convert(i / 100000) + " Lakh "
                       + ((i % 100000 > 0) ? " " + convert(i % 100000) : "");
           return convert(i / 10000000) + " Crore "
                   + ((i % 10000000 > 0) ? " " + convert(i % 10000000) : "");
       }

   }
