Find day of the week by inserting date in format dd/MM/yyyy

Question

Hi guys

I want to get day of the week by inserting the date but using format dd/MM/yyyy

Now this is what i did..

Session["StartDate"]=09/10/2011
string ddMMyyyyFormat = Session["StartDate"].ToString();//Date in dd/MM/yyyy
string MMddyyyFormat =Convert.ToDateTime(ddMMyyyyFormat).ToString("MM/dd/yyyy");

DateTime MMddyyyyDate = Convert.ToDateTime(MMddyyyFormat);
string dayOfWeek = MMddyyyyDate.DayOfWeek.ToString();

Now i get the day of the week as "Saturday" because its not converted to format MM/dd/yyyy

Try: DateTime MMddyyyyDate = DateTime.ParseExact(MMddyyyFormat MM/dd/yyyy null); string dayOfWeek = MMddyyyyDate.DayOfWeek.ToString();

You can use DateTime.Parse if you use an overload which takes an IFormatProvider object. You can then pass it a CultureInfo object for a culture which displays dates with the month before the day such as en-US: var ci = System.Globalization.CultureInfo.CreateSpecificCulture(en-US); DateTime MMddyyyyDate = DateTime.Parse(MMddyyyFormat ci); string dayOfWeek = MMddyyyyDate.DayOfWeek.ToString(); You can also use DateTime.TryParse in a similar fashion: DateTime MMddyyyyDate; if (DateTime.TryParse(MMddyyyFormat ci 0 out MMddyyyyDate)) { string dayOfWeek = MMddyyyyDate.DayOfWeek.ToString(); // do something }
