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

Anele Ngqandu

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
}

try this:

string ddMMyyyyFormat = "09/10/2011";

DateTime strDate = Convert.ToDateTime(ddMMyyyyFormat.Substring(3, 2) + "/" + ddMMyyyyFormat.Substring(0, 2) + "/" + ddMMyyyyFormat.Substring(6, 4));

string dayofWeek = strDate.DayOfWeek.ToString();
