Question

I have the following statement

DateTime now = DateTime.Now; string test = string.Format('{0}{1}{2}{3}', now.Day, now.Month, now.Year, now.Hour); 

This gives me:

test = '242200915' 

But I’d like to have something like:

test = '2402200915' 

So the question is, how can I enforce the string formatter to output each int with the width of 2 while padding with zeroes?

Answer 1

You can use string.Format('{0:000} {0:D3}', 7)
to get 007 007

And here is a useful overview on MSDN: Custom Numeric Format Strings
