String Format

[Guest]

Hey,

I have an int32 and a string.

The integer contains : 56
I want to fill up the string as follows : "00056"
The string must have a lenght of 5 en must be filled up with leading zero's.
How can I do this? I looked a little bit arround and don't find the way to
do this.

Thanks,
jac

string s = i.ToString("00000");

Have you tried the PadLeft method of the String class?

Try:
int n = 56
string str = n.ToString();;
string str2 = str.PadLeft(5,'0');

where 5 is the number of characters in your new string and '0' is the
padding character. If you try it with str as "156", the result would be
"00156". It simply pads out the string to the length you require. You can
also PadRight to add digits or characters to the end of your string.

Don't forget to parse it before using it as an int again. I.E.

int n = Int32.Parse(str2);

Hope that helps.

Having re-read your post, you don't need to parse it back to an int.

Thanks, Brian. I wasn't aware of that one (but then I've only been
programming a few months).

Jac,
In addition to:

string s = i.ToString("00000");

You could use:

string s = i.ToString("D5");

int d = 56;
textBox1.Text = d.ToString("0#####");
