Question

I am looking for a solution to get system date time format.

For example: if I get DateTime.Now? Which Date Time Format is this using? DD/MM/YYYY etc

Answer 1

If it has not been changed elsewhere, this will get it:

string sysFormat = CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern;

If using a WinForms app, you may also look at the UICulture:

string sysUIFormat = CultureInfo.CurrentUICulture.DateTimeFormat.ShortDatePattern;

Note that DateTimeFormat is a read-write property, so it can be changed.
