You can manully add zero before string.

You need to format it as a string, rather than leave it as an int. Ints have no concept of leading zeros, so unless you format it, it can't "keep any zeros" at the front.
Try:

C#

string s = myIntValue.ToString("D6");

how and where must i use
string s = myIntValue.ToString("D6");

I would have to guess (since you don't specify what you are doing with it that well, but probably what you want is to replace:
SerialListBox.Items.Add("RET"+(j + i + 1));
With:
SerialListBox.Items.Add("RET"+(j + i + 1).ToString("D6"));
Or better:
SerialListBox.Items.Add(string.Format("RET{0:D6}", j + i + 1));

i have one combo box one textbox and one listbox.
my combobox has value 002 or 001 any thind with zero in the begining.
my textbox have quantity number. how many times the value in combobox will increment . and the result will be shown in listbox.
and the iam using top code to do all this.
now my code is not incrementing any value which statrs with zero.
it skip zero and increment rest.
i want it must increment like
001
002
003
not
1
2
3
and leave zero behind

i am getin error "formate specifier was invalid" for these codes
SerialListBox.Items.Add("RET"+(j + i + 1).ToString("D6"));
SerialListBox.Items.Add(string.Format("RET{0:D6}", j + i + 1));

I just double checked, and I don't. Are you sure you typed it correctly?
