The DayOfWeek enumeration represents the day of the week in calendars that have seven days per week. This enumeration ranges from zero, indicating Sunday, to six, indicating Saturday.
This enumeration is useful when it is desirable to have a strongly typed specification of the day of the week. For example, this enumeration is the type of the property value for the DateTime.DayOfWeek property.
The following example demonstrates the DateTime.DayOfWeek property and the DayOfWeek enumeration.
