Introduction:
In my previous article I have explained about how to validate emailid using javascript. In this article I am going to explain about code used to convert rupees(numbers) into words using C#.Net.
Explanation:
For explanation purpose I have a page. It has a textbox to input the numbers. And when you click on the convert to words button then it will convert the input numbers into words and shows it in the below label.
Below is the C# code used to do this functionality.
public static string NumbersToWords(int inputNumber)
{
    int inputNo = inputNumber;

    if (inputNo == 0)
        return "Zero";

    int[] numbers = new int[4];
    int first = 0;
    int u, h, t;
    System.Text.StringBuilder sb = new System.Text.StringBuilder();

    if (inputNo < 0)
    {
        sb.Append("Minus ");
        inputNo = -inputNo;
    }

    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 " };

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

    for (int i = 3; i > 0; i--)
    {
        if (numbers[i] != 0)
        {
            first = i;
            break;
        }
    }
    for (int i = first; i >= 0; i--)
    {
        if (numbers[i] == 0) continue;
        u = numbers[i] % 10; // ones
        t = numbers[i] / 10;
        h = numbers[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();
}

Below is the aspx code.
<form id="form1" runat="server">
<div>
    <table style="width: 50%;">
        <tr>
            <td>
                Input Number
            </td>
            <td>
                <asp:TextBox ID="txtNumber" runat="server"></asp:TextBox>
            </td>
        </tr>
        <tr>
            <td>
            </td>
            <td>
                <asp:Button ID="btnConvert" Text="Convert To Words" runat="server" OnClick="btnConvert_Click" />
            </td>
        </tr>
        <tr>
            <td colspan="2">
                <asp:Label ID="lblWords" runat="server"></asp:Label>
            </td>
        </tr>
    </table>
</div>
</form>

  3. Nice code.However prints "and" at the beggining for numbers < 100.eg: if input number is 25 output is "and Twenty Five" instead of "Twenty Five"
