A quick question,

I have a string with a date in european format, e.g. "30/4/2006".

What is the FASTEST way to produce the corresponding string in USA
format
"4/30/2006" and asian format "2006/4/30" ?

Pam,
Define "fastest", I would be more concerned with the "proper" way of doing
it.

If I had a date in d/m/y format & wanted m/d/y or y/m/d formats I would
simply use DateTime.Parse & DateTime.ToString. As Parse & ToString are the
"proper" ways of doing (who better then the type itself to have convert to &
from various formats).

Something like:

        Const dmy As String = "d/M/yyyy"
        Const mdy As String = "M/d/yyyy"
        Const ymd As String = "yyyy/M/d"

        Dim european As String = "30/4/2006"

        Dim someDate As Date = DateTime.ParseExact(european, dmy, Nothing)

        Dim usa As String = someDate.ToString(mdy)
        Dim asian As String = someDate.ToString(ymd)

NOTE: Convert.ToString & Convert.ToDateTime ultimately call DateTime.Parse &
DateTime.ToString...

Thank you Jay, it helps a lot !

I have a doubt, why for the year there are 4 yyyy and for day/month on
one
(intuitively one would expect 2 chars ).

Thanks again,

PS by "fast" I meant the most efficient way in terms of speed of
execution. Probably the one you suggest :-)

I used one on day & month so as to allow the 1st thru the 9th. without
requiring a leading zero.

It allows "30/4/2006" rather then require "30/04/2006"

Very good. Thank you very much!

I guess that with the same logic it could be safe to use only 2 chars
for the year (yy) ...

Jay,

Just for you as American,

The second is AFAIK more common in Europe, that as well for the days.
