How to get the day name from a selected date?
I have this : Datetime.Now();
开发者_开发百科or 23/10/2009
Friday
For local date-time (GMT-5) and using Gregorian calendar.
//default locale
System.DateTime.Now.DayOfWeek.ToString();
//localized version
System.DateTime.Now.ToString("dddd");
To make the answer more complete:
DayOfWeek MSDN article
If localization is important, you should use the "dddd" string format as Fredrik pointed out - MSDN "dddd" format article
If you want to know the day of the week for your code to do something with it, DateTime.Now.DayOfWeek
will do the job.
If you want to display the day of week to the user, DateTime.Now.ToString("dddd")
will give you the localized day name, according to the current culture (MSDN info on the "dddd" format string).
System.Threading.Thread.CurrentThread.CurrentUICulture.DateTimeFormat.GetDayName(System.DateTime.Now.DayOfWeek)
or
System.Threading.Thread.CurrentThread.CurrentUICulture.DateTimeFormat.GetDayName(DateTime.Parse("23/10/2009").DayOfWeek)
DateTime.Now.DayOfWeek
quite easy to guess actually.
for any given date:
DateTime dt = //....
DayOfWeek dow = dt.DayOfWeek; //enum
string str = dow.ToString(); //string
DateTime now = DateTime.Now
string s = now.DayOfWeek.ToString();
Here is more simple
DateTime dt;
string yourdate = dt.DayOfWeek.ToString()
better than declare redundant DayOfWeek
try this:
DateTime.Now.DayOfWeek
You're looking for the DayOfWeek property.
Here's the msdn article.
What about if we use String.Format here
DateTime today = DateTime.Today;
String.Format("{0:dd-MM}, {1:dddd}", today, today) //In dd-MM format
String.Format("{0:MM-dd}, {1:dddd}", today, today) //In MM-dd format
(DateTime.Parse((Eval("date").ToString()))).DayOfWeek.ToString()
at the place of Eval("date"),you can use any date...get name of day
I use this Extension Method:
public static string GetDayName(this DateTime date)
{
string _ret = string.Empty; //Only for .NET Framework 4++
var culture = new System.Globalization.CultureInfo("es-419"); //<- 'es-419' = Spanish (Latin America), 'en-US' = English (United States)
_ret = culture.DateTimeFormat.GetDayName(date.DayOfWeek); //<- Get the Name
_ret = culture.TextInfo.ToTitleCase(_ret.ToLower()); //<- Convert to Capital title
return _ret;
}
Random Rnd = new Random();
RandomDates Rdate = new RandomDates();
PaymentDetails Payd = new PaymentDetails();
DayOfWeek strDay = DateTime.Today.DayOfWeek;
var dateTime = DateTime.Now;
var dateValue2 = dateTime.ToString(@"MM\/dd\/yyyy");
StepDescription = "Fill MatterInformation. ";
Console.Write(" Input the Day : ");
dt = Convert.ToInt32(Console.ReadLine());
Console.Write(" Input the Month : ");
mn = Convert.ToInt32(Console.ReadLine());
Console.Write(" Input the Year : ");
yr = Convert.ToInt32(Console.ReadLine());
DateTime d = new DateTime(2021, 04, yr);
var culture = System.Threading.Thread.CurrentThread.CurrentCulture;
var diff = d.DayOfWeek - culture.DateTimeFormat.FirstDayOfWeek;
if (diff < 0)
diff += 7;
var x = d.AddDays(-diff).Date;
dateTime = DateTime.Now;
dateValue2 = dateTime.ToString(@"MM\/dd\/yyyy");
Console.WriteLine($"Date Value: {dateValue2}");
// strDay =
}
if (!strDay.Equals("Sunday") | !strDay.Equals("Saturday"))
{
Console.WriteLine("___________________OK____________________________________________");
// string NotificateionDate = Rdate.DateWithin_PastDays(Rnd.Next(30, 260)).ToString(@"MM\/dd\/yyyy");
// CustomLibrary.seWaitUntilElementIsVisible(10, NotiFiedDateTab.Actions.seGetLocator(), "NotiFiedDateTab");
NotiFiedDateTab.Actions.Set(ControlPropertyNames.Text, dateValue2);
}
else
{
Console.WriteLine("_________________________NOT______________________________________");
if (strDay.Equals("Sunday"))
{
dateTime = dateTime.AddDays(-2);
dateValue2 = dateTime.ToString(@"MM\/dd\/yyyy");
NotiFiedDateTab.Actions.Set(ControlPropertyNames.Text, dateValue2);
}
else if (strDay.Equals("Saturday"))
{
dateTime = dateTime.AddDays(-1);
dateValue2 = dateTime.ToString(@"MM\/dd\/yyyy");
NotiFiedDateTab.Actions.Set(ControlPropertyNames.Text, dateValue2);
}
}

DateTime mydate = new DateTime(year,month,day);
string formatteddate = string.Format("{0:dddd}", mydate);
Console.WriteLine("The day should be " + formatteddate);
}
