    Hi, Seem to be very simple but it's not working with following conversion methods. Trying to convert from string to integer 0's missing in the Output. string strInput = "06461"; int iResult = Convert.ToInt32(strInput) (or) int iResult = int.Parse(strInput); Output : 6461 (note 0's missing) How to get the zero also in the output as 06461. Reg, Subbu

    That is normal: an Int of "06461" = 6461 (you don't put 06461 in a calculator, do you ? :^) ) Keep the number as a string to show the leading zero's.

      Use an explicit format string when you print the int:

      int i = 6461;
      Console.Writeline(i);
      Console.WriteLine(i.ToString("D5"));

      will print:

      6461
      06461

        Thanx for your reply. How to keep that as a string and expand it. Example: string strInput = AD01234-AD01237; This need to be Expand like AD01234,AD01235,AD01236,AD01237. - Spliting the string in to 2 with -(hypen) - From 1st string process from the last and get only numbers and vice versa. - finally by using the For loop process from starting Number to end will be expanded. But in this case need to convert to int then only it can be possible. how to achieve this? Reg, subbu

          Thanks for your quick response. But one question how to get the final value as a integer rather than string. Any Other Option? int iResult = 06461; /// Output. REg, Sbubbu

            Oh boy. :sigh: An integer is a number. Like any number, it can have an infinite number of zeros in front of it. Take your house, or flat number - let us say it is six, and the address is Lemon Street. You live at 6 Lemon street. You also could say "I live at 0000006 Lemon Street, and your letters would still arive - but the postman might think you are a little wierd. You can happily tell Visual studio:

            int i = 000000000006461;

            or

            int i = 6461;

            or

            int i = 0006461;

            etc., etc. They all mean the same. A string representation of a number is more like a telephone number: "0123 456789" is a different number to "123 456789" because the exchange will not see it as having an area code, as the leading zero is missing. But, you cannot add two telephone numbers together!

                  yes, sure. and how many zeroes are missing? 1? one hundred? 2. you could (I don't say "should") do what you want with strings and characters, i.e. come up with a method that "increments a string". This is how it would go: a. copy the original string; b. look for the rightmost digit that you haven't processed yet; c. add one to it i.e. replace '0' by '1', or '1' by '2', etc d. if in step c you replaced '9' by '0' then goto b e. done with possible refinement: if b fails, prefix a '1' :)

                      You can split a string like this:

                      string[] ArrayOfStrings;
                      string s = "AD0001-AD0002-AD0003";
                      ArrayOfStrings = s.Split('-');

                      For the rest I not sure what u mean...
