| System.Enum Class |
|
| |
| Description | |
|
Enumerations in .Net are similar to enumerations in native Delphi. They provide a means of naming constant values, with a particular enumeration value only allowed to have one of the named values.
For example, the DayOfWeek enumeration has the following contents :
| Sunday | = 0 |
| Monday | = 1 |
| Tuesday | = 2 |
| Wednesday | = 3 |
| Thursday | = 4 |
| Friday | = 5 |
| Saturday | = 6 |
Unlike native Delphi, .Net Enumerations can be optionally treated as Flags. They therefore become equivalent to Sets in native Delphi. An enum is a set of flags when the [FlagsAttribute] is specified immediately prior to the Enum definition :
type
[FlagsAttribute]
Flags = (Sexy, Clever, Handsome);
