El valor de las constantes de la DayOfWeek enumeración va de DayOfWeek.Sunday a DayOfWeek.Saturday. Si se convierte en un entero, su valor va de cero (que indica DayOfWeek.Sunday) a seis (lo que indica DayOfWeek.Saturday).
La DayOfWeek propiedad devuelve una constante enumerada; no refleja la configuración regional y de idioma de un sistema. Para recuperar una cadena que representa un nombre de día de la semana localizado para una fecha determinada, llame a una de las sobrecargas del ToString método que incluye un format parámetro y pásela las ddd cadenas de formato personalizado o dddd .
