Comentarios

El valor de las constantes de la enumeración DayOfWeek va de DayOfWeek.Sunday a DayOfWeek.Saturday.The value of the constants in the DayOfWeek enumeration ranges from DayOfWeek.Sunday to DayOfWeek.Saturday. Si se convierte en un entero, su valor va de cero (que indica DayOfWeek.Sunday) a seis (lo que indica DayOfWeek.Saturday).If cast to an integer, its value ranges from zero (which indicates DayOfWeek.Sunday) to six (which indicates DayOfWeek.Saturday).

También puede mostrar el nombre del día de la semana de una fecha determinada mediante el especificador de formato "D" o el especificador de formato personalizado "dddd".You can also display the weekday name of a particular date by using the "D" format specifier or the "dddd" custom format specifier. Por ejemplo:For example:

DateTimeOffset displayDate = new DateTimeOffset(2008, 1, 1, 13, 18, 00, 
                                                DateTimeOffset.Now.Offset);
Console.WriteLine("{0:D}", displayDate);  // Output: Tuesday, January 01, 2008                     
Console.WriteLine("{0:d} is a {0:dddd}.", 
                  displayDate);           // Output: 1/1/2008 is a Tuesday.
Dim displayDate As New DateTimeOffset(#1/1/2008 1:18PM#, _
                                      DateTimeOffset.Now.Offset)
Console.WriteLine("{0:D}", displayDate)    ' Output: Tuesday, January 01, 2008                     
Console.WriteLine("{0:d} is a {0:dddd}.", _
                  displayDate)             ' Output: 1/1/2008 is a Tuesday.

Tenga en cuenta que la cadena devuelta mediante la llamada al método ToString del miembro de enumeración DayOfWeek que devuelve esta propiedad no está localizada.Note that the string returned by calling the ToString method of the DayOfWeek enumeration member that is returned by this property is not localized. Para extraer una cadena que contiene el nombre del día de la semana de la referencia cultural actual o de una referencia cultural concreta, llame al método ToString con el especificador de formato personalizado "dddd".To extract a string that contains the weekday name of the current culture or of a specific culture, call the ToString method with the "dddd" custom format specifier. Por ejemplo, en el código siguiente se muestra el nombre del día de la semana para una fecha usando la referencia cultural fr-fr.For example, the following code displays the weekday name for a date using the fr-fr culture.

DateTimeOffset thisDate = new DateTimeOffset(2007, 6, 1, 6, 15, 0, 
                                             DateTimeOffset.Now.Offset);
string weekdayName = thisDate.ToString("dddd", 
                                       new CultureInfo("fr-fr")); 
Console.WriteLine(weekdayName);                  // Displays vendredi     
Dim thisDate As New DateTimeOffset(#6/1/2007 6:15AM#, _
                                      DateTimeOffset.Now.Offset)
Dim weekdayName As String = thisDate.ToString("dddd", _
                            New CultureInfo("fr-fr")) 
Console.WriteLine(weekdayName)                        ' Displays vendredi
