How to custom format a date overriding regional settings..

[SharmaPunit]

I want to display a date in m/d/yy format. I have written the following lines of code and it is running perfectly till the date format in the regional settings of my computer is set to mm/dd/yyyy or any other which have '/' as a seperator.

As soon as I change my date format in the control panel->regional settings-> date to yyyy-mm-dd i.e. with a seperator '-', the following lines of code returns date with '-' as a seperator(m-d-yyyy). I want to show it as m/d/yy

DateTime date = DateTime.Now;
TxtDate.Text = String.Format("{0:M/d/yy}", date);

I have tried this also:

TxtDate.Text = DateTime.now.to_string("m/d/yy");

Your help will be highly appreciated.
