Add zero in front of single digit day in VB

Question

I have the following codes in visual basic that display the day/month/year

CStr(vDay) & "/" & (vMonth) & "/" & (vYear) & " " & (vHour) & ":" & (vMinute) & ":" &     (vSecond), DateTime.Now

How can I add a "0" in front of a single digit day and month?

Answer 1

If your variables are integers, you can use the "D" format specifier to set how many digits you want, for instance:

vMonth.ToString("D2")

However, if you already have the value in a Date object, then you can just use it's built-in formatting, which would be easier:

DateTime.Now.ToString("dd/MM/yyyy HH:mm:ss")

Answer 2

To account for all situations, PadLeft is most helpful. The first part is set total width for the integer, the second part is the character to be placed there.

vMonth.ToString().PadLeft(2, "0"c)

This would place a zero in front of single digit months.
