number to word conversion code required in c#.net

ravi7673

hi guys,

i have 1 textbox & 1 label on a page. textbox accepts numeric value & it should convert it into words & display it on label.

For eg :
If textbox accepts 10863 then it should display its equivalent value in label as "Ten Thousand Eight Hundred Sixty Three Only"

Thanks in advance for any help or solution.

Regards
ravindra.

I hope following code will solve ur problem:


class NumberToWordsConvertor
{
// Single-digit and small number names
private string[] _smallNumbers = new string[] {"Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven", "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen", "Seventeen", "Eighteen", "Nineteen"};

// Tens number names from twenty upwards
private string[] _tens = new string[] { "", "", "Twenty", "Thirty", "Forty", "Fifty", "Sixty", "Seventy", "Eighty", "Ninety" };

// Scale number names for use during recombination
private string[] _scaleNumbers = new string[] { "", "Thousand", "Million", "Billion" };



// Converts an integer value into English words
public string NumberToWords(int number)
{
// Zero rule
if (number == 0)
return _smallNumbers[0];

// Array to hold four three-digit groups
int[] digitGroups = new int[4];

// Ensure a positive number to extract from
int positive = Math.Abs(number);

// Extract the three-digit groups
for (int i = 0; i < 4; i++)
{
digitGroups[i] = positive % 1000;
positive /= 1000;
}

// Convert each three-digit group to words
string[] groupText = new string[4];

for (int i = 0; i < 4; i++)
groupText[i] = ThreeDigitGroupToWords(digitGroups[i]);

// Recombine the three-digit groups
string combined = groupText[0];
bool appendAnd;

// Determine whether an 'and' is needed
appendAnd = (digitGroups[0] > 0) && (digitGroups[0] < 100);

// Process the remaining groups in turn, smallest to largest
for (int i = 1; i < 4; i++)
{
// Only add non-zero items
if (digitGroups[i] != 0)
{
// Build the string to add as a prefix
string prefix = groupText[i] + " " + _scaleNumbers[i];

if (combined.Length != 0)
prefix += appendAnd ? "" : ", ";

// Opportunity to add 'and' is ended
appendAnd = false;

// Add the three-digit group to the combined string
combined = prefix + combined;
}
}

// Negative rule
if (number < 0)
combined = "Negative " + combined;

return combined;
}



// Converts a three-digit group into English words
private string ThreeDigitGroupToWords(int threeDigits)
{
// Initialise the return text
string groupText = "";

// Determine the hundreds and the remainder
int hundreds = threeDigits / 100;
int tensUnits = threeDigits % 100;

// Hundreds rules
if (hundreds != 0)
{
groupText += _smallNumbers[hundreds] + " Hundred";

if (tensUnits != 0)
groupText += "";
}

// Determine the tens and units
int tens = tensUnits / 10;
int units = tensUnits % 10;

// Tens rules
if (tens >= 2)
{
groupText += _tens[tens];
if (units != 0)
groupText += "" + _smallNumbers[units];
}
else if (tensUnits != 0)
groupText += _smallNumbers[tensUnits];

return groupText;
}
}
