I am trying to change the default date format by the way below but the format wont change and there is no errors

I am excepting to get date in Arabic format. What I am getting now is the default system format date like this (12:00:00 03/01/2011) while I want to overwrite the system format date

Note: Working under oracle11g 

TBNextDate.Text = Convert.ToDateTime(oraReder[4])
                         .ToString("hh:mm:ss dd/MM/yyyy", new CultureInfo("ar-AE"));

    What do you expect the output to be and what are you getting? Is `oraReder[4]` a valid date? – D Stanley Dec 13 '16 at 19:35

According to MSDN:

The provider parameter defines the pattern that corresponds to the standard format specifiers, as well as the symbols and names of date and time components.

When you specify a specific format like you do that does not include any name specifiers, the only thing the culture changes is the separator symbol (e.g. / or .)

If you want to use a date pattern specific to that culture, use a standard format string instead:

TBNextDate.Text = Convert.ToDateTime(oraReder[4]).ToString("d", new CultureInfo("ar-AE"));
