`recordnumber.tostring("00000");` doesn't do anything by itself, you should do it like `stringArray1[i] = recordnumber.ToString("000000") + "DA01" + customerId + "...` — Ulugbek Umirov, Jun 09 '14 at 12:17

string newstring = yourstring.PadLeft(6, '0');

or

string formatted = yourstring.ToString("d6");
