public  string NumberToText(int number)
    {
        if (number == 0) return "Zero";


        if (number == -2147483648) return "Minus Two Hundred and Fourteen Crore Seventy Four Lakh 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 < 0)
        {
        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 ", "Lakh ","Crore "};


        num[0] = number % 1000; // units
        num[1] = number / 1000;
        num[2] = number / 100000;
        num[1] = num[1] - 100 * num[2]; // thousands
        num[3] = number / 10000000; // crores
        num[2] = num[2] - 100 * num[3]; // lakhs


        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 == 0) sb.Append("and ");


        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();
    }
