Datetime format issue?

Kannabiran B

Hi,
I finished developing the .net windows application.problem is in date format.the application developed with the date format of "MM/dd/yyyy" with this appication working fine.but now i want to change the dateformat to "dd/MM/yyyy" by setting this format im getting the folling error "String was not regcognized as valid date format". i have to change the format in one place so that it gets effect in all over the application.

i have tried withe the below code.but its not working.

CultureInfo culture = (CultureInfo)CultureInfo.CurrentCulture.Clone();
culture.DateTimeFormat.ShortDatePattern = "dd/MM/yyyy";
culture.DateTimeFormat.LongTimePattern = "";
System.Threading.Thread.CurrentThread.CurrentCulture = culture;

Regards
Kanna

It's working. You may missed the correct conversion. Just check below boldded lines. You need to convert Date to the the specified format you set using ToShortDateString, ToLongDateString etc...
CultureInfo culture = (CultureInfo)CultureInfo.CurrentCulture.Clone();
            culture.DateTimeFormat.ShortDatePattern = "dd/MM/yyyy";
            culture.DateTimeFormat.LongTimePattern = "";
            System.Threading.Thread.CurrentThread.CurrentCulture = culture;
            MessageBox.Show(DateTime.Now.ToShortDateString());
            culture.DateTimeFormat.ShortDatePattern = "MM/dd/yyyy";
            MessageBox.Show(DateTime.Now.ToShortDateString());
            culture.DateTimeFormat.LongDatePattern = "MMM/dddd/yyyy";
            MessageBox.Show(DateTime.Now.ToLongDateString());
