    {

int seconds = 10000;

       string Time = ConvertToHHMMSS1(seconds);

       //string Time = ConvertToHHMMSS2(seconds);

    }

private string ConvertToHHMMSS1(int seconds)

    {

        return string.Format("{0}:{1}:{2}", Hours, ts.Minutes, ts.Seconds);

    }

private string ConvertToHHMMSS2(int seconds)

  {

    return string.Format("{0:00}:{1:00}:{2:00}", seconds / 3600, (seconds / 60) % 60, seconds % 60);

C# string formatting

Numeric Format Specifiers
Specifier	Description	Example	C#
c	Currency; specify the number of decimal places	$12,345.00	string.Format ("Currency: {0:c}", iNbr)
d	Whole numbers; specifies the minimum number of digits - zeroes will be used to pad the result	12345	string.Format ("Whole: {0:d}", iNbr)
e	Scientific notation; specifies the number of decimal places	1.2345e+004	string.Format ("Exponential: {0:e}", iNbr)
f	Fixed-point; specifies the number of decimal places	12345.00	string.Format ("Fixed: {0:f3}", iNbr)
n	Fixed-point with comma separators; specifies the number of decimal places	12,345.00	string.Format ("Fixed formatted: {0:n3}", iNbr)
p	percentage; specifies the number of decimal places	1,234,500.00%	string.Format ("Percentage: {0:p2}", iNbr)
x	Hexadecimal	3039	string.Format ("Hexadecimal: {0:x}", iNbr)

Example :

private string ConvertToPercent(string textToConvert)

  {

    return String.Format("{0:P}", Convert.ToDecimal(textToConvert));

  }

private string CovertToInteger(string textToCovert)

  {

    return String.Format("{0:n0}", Convert.ToInt32(textToCovert));

  }

private string ConvertToDecimal(string textToCovert)

  {

    return String.Format("{0:f0}", Convert.ToDecimal(textToCovert));

  }

 private string ConvertToCurrency(string textToConvert)
