Question

string strI;

    for(int i = 1;i<100;i++)
        strI = i.ToString();

in here, if i is 1 then strI is '1'

But I want to get '01'

or '001'

it looks quite easy. but there's only article about datetime.tostring("yyyy-MM-dd") :(

Answer 1

ToString can take a format. try:

i.ToString("000");

Answer 2

i.ToString("00")

or

i.ToString("000")

depending on what you want

Look at the MSDN article on custom numeric format strings for more options: http://msdn.microsoft.com/en-us/library/0c899ak8(VS.71).aspx

Answer 3

This blog post is a great little cheat-sheet to keep handy when trying to format strings to a variety of formats.
