As advised by you have already seen this link. And using that I tried in my code like:
//DateTime dateValue = new DateTime(2008, 6, 11);
//string v_d=dateValue.ToString("dddd");
//Console.WriteLine(dateValue.ToString("dddd")
I tried with the variable like: DateTime dateValue = new DateTime(v_DespatchDate);
It didnt work. The error is: Error 4 Argument '1': cannot convert from 'string' to 'long'.
I just wanted to know how that variable should be used.
Thank you.

That implies that you are trying to pass a string to a DateTime Constructor:
string v_DespatchDate = v_todaydt.AddDays(7).Date.ToString("yyyy/MM/dd");
DateTime dateValue = new DateTime(v_DespatchDate);
Which is unnecessary, when you have the datetime value in the middle already!
Try
DateTime v_todaydt = DateTime.Today;
DateTime dateValue = v_todaydt.AddDays(7).Date;
string v_DespatchDate = dateValue.ToString("yyyy/MM/dd");
string dayOfWeek = dateValue.ToString("dddd");

Solution 3

DateTime v_todaydt = DateTime.Today;
v_DespatchDate = v_todaydt.AddDays(7).Date.ToString("D");

plz try this................

Hi

Try like this..

C#

DateTime v_todaydt = DateTime.Today;
      var v_DespatchDate = v_todaydt.AddDays(7).Date.ToString("yyyy/MM/dd");

      DateTime dateTime = DateTime.ParseExact(v_DespatchDate, "yyyy/MM/dd", System.Globalization.CultureInfo.InvariantCulture);

      var dayname = (dateTime.ToString("dddd"));

for casting use : DateTime.ParseExact

for getting day name use : .ToString("dddd")
