[.net] How to convert a Date to a formatted string in VB.net?

There seems to be a million questions here on converting a string to a Date, but not vice-versa. When I convert a Date object to a string using mydate.toString I get a string in the format 16/01/2013 13:00:00.

But what I really want is 2013-01-16 13:00:00. I can't see any functions on the Date object that do this for me, do I need to use a regex or something instead?

Dim timeFormat As String = "yyyy-MM-dd HH:mm:ss"
objBL.date = Convert.ToDateTime(txtDate.Value).ToString(timeFormat)

you can do it using the format function, here is a sample:

Format(mydate, "yyyy-MM-dd HH:mm:ss")

I like:

Dim timeFormat As String = "yyyy-MM-dd HH:mm:ss"
myDate.ToString(timeFormat)

Easy to maintain if you need to use it in several parts of your code, date formats always seem to change sooner or later.

myDate.ToString("yyyy-MM-dd HH:mm:ss")

the capital HH is for 24 hours format as you specified
