formatting strings with leading characters

[Guest]

How can I add characters to an incomplete string. I want it:
Ex:
"12" to "0012"

That's exactly what I need, I prefer using string. If there's no way, I'd
like to know how make an integer to change like the above example.

str="00" & 12 in vb.net
str="00" + 12 in C#

Try it

Using integers:

int i = 12;
Console.WriteLine(i.ToString("0000"));
