how many zeros do you want?? You can use string.pad

int count = 1102;
            int NumOfZeros = 10;
            string s = count.ToString().PadLeft(NumOfZeros, '0');

there is also the number formatter.

count.ToString("D10");

PadLeft is pretty slick. I had never noticed it. I always used the string formatter. Thanks! – Ritch Melton Mar 03 '11 at 05:10

If you are storing this number as an int (and you should) 1102 annd 00001102 are the same thing. Use string formatting later when you need to output the value with some zeros.

1102.ToString("D8") will give you the string "00001102"

Also, possible duplicates of this question: Pad with leading zeros

@RAHUL: is it meant to be used as a number or as a string? – Dyppl Mar 03 '11 at 05:10

String num = "000001101";
int item = int.Parse(num);
item++;
String output = item.ToString("D8");

You need to use String.Format("{0:00000000}", 1101);, which would be 00001101

Try int.parseInt(startNo) instead of converting it to a char array.
