I set the date format as "MM/dd/yyyy" on control panel. Then, I use
System.Globalization.DateTimeFormatInfo.CurrentInfo.ShortDatePattern to
return short date format. But it has not return my expected format, which
return 'M/d/yyyy'. How should I do?

what? "d"???

I only want to gather the date format string like as "MM/dd/yyyy".

That's exactly what "d" does, according to the on-line help. Try it!

Unless CultureInfo.UseUserOverride is true, settings in Control Panel
will not be used by the CultureInfo class. However, this property can
only be set at construction time, so you may need to create a new
instance of CultureInfo instead of using CultureInfo.CurrentCulture:

CultureInfo info = new CultureInfo(CultureInfo.CurrentCulture.LCID,
true);
string shortDateFormat = info.DateTimeFormat.ShortDatePattern;
 
I tried this test, but it returns not my expected.

I found this line can return my result. Pls use it.
System.Globalization.DateTimeFormatInfo.InvariantInfo.ShortDatePattern;
 
Hi ABC, you said that you wanted to retrieve the short date pattern
that you specified in Control Panel, right? As far as I know, the
invariant info always returns the same thing whatever culture and
settings are. I think it returned what you expected was just a
coincidence. Have you tried changing things in Control Panel and run it
again?

I think the Current info would work. I suspect that you have changed it
prevously somewhere in your application. To test this, you might write
a simple console program which writes current culture info on screen.

If you have changed the app current culture, and then want to get the
user's regional settings in Control Panel, you should backed up the
current culture before changing it. A alternative is using my code
above, but instead of CultureInfo.CurrentCulture.LCID, you might want
to get the LCID by using Windows API GetUserDefaultLCID function.
