在 app.config 中，我提供了一个循环字符串值：“Monday”、“Tuesday”、...、“Daily”。从那个值我想分配一个<Flags()>枚举。简单地使用DayOfWeek并不能让我将流程标记为日常工作。是否有可用的.Net 类提供星期几作为标志？

与此同时，我设计了以下内容：

<Flags()> _
Public Enum enumExportCycle As Integer
    Monday = DayOfWeek.Monday
    Tuesday = DayOfWeek.Tuesday
    Wednesday = DayOfWeek.Wednesday + 1
    Thursday = DayOfWeek.Thursday + 4
    Friday = DayOfWeek.Friday + 11
    Saturday = DayOfWeek.Saturday + 26
    Sunday = DayOfWeek.Sunday + 64
    Daily = Monday Or Tuesday Or Wednesday Or Thursday Or Friday Or Saturday Or Sunday
End Enum

感觉有点骇人听闻，我正在寻找更好的方法。

这是 Windows Mobile 上 PocketOutlook 的 DaysOfWeek 枚举（用于设置重复）的链接：http: //msdn.microsoft.com/en-us/library/microsoft.windowsmobile.pocketoutlook.daysofweek.aspx

它定义了一个这样的枚举：

[Flags] 
public enum DaysOfWeek
{
  Sunday = 1,
  Monday = 2,
  Tuesday = 4,
  Wednesday = 8,
  Thursday = 16,
  Friday = 32,
  Saturday = 64
}

我会为 Daily 定义一个类似的枚举（也许每个工作日和每个周末：

[Flags] 
public enum DaysOfWeek
{
  Sunday = 1,
  Monday = 2,
  Tuesday = 4,
  Wednesday = 8,
  Thursday = 16,
  Friday = 32,
  Saturday = 64,
  Daily = Sunday + Monday + Tuesday + Wednesday + Thursday + Friday + Saturday,
  Weekdays = Monday + Tuesday + Wednesday + Thursday + Friday,
  Weekends = Sunday + Saturday
}

this will work, right?

<Flags()> _
Public Enum enumExportCycle As Integer
    Monday = 1
    Tuesday = 2
    Wednesday = 4
    Thursday = 8
    Friday = 16
    Saturday = 32
    Sunday = 64
    Daily = Monday Or Tuesday Or Wednesday Or Thursday Or Friday Or Saturday Or Sunday
End Enum

or this

<Flags()> _
Public Enum enumExportCycle As Integer
    Monday = 2 ^ DayOfWeek.Monday
    Tuesday = 2 ^ DayOfWeek.Tuesday
    Wednesday = 2 ^ DayOfWeek.Wednesday
    Thursday = 2 ^ DayOfWeek.Thursday
    Friday = 2 ^ DayOfWeek.Friday
    Saturday = 2 ^ DayOfWeek.Saturday
    Sunday = 2 ^ DayOfWeek.Sunday
    Daily = Monday Or Tuesday Or Wednesday Or Thursday Or Friday Or Saturday Or Sunday
End Enum

since DayOfWeek start from 0 (Sunday) to 6 (Saturday)
