Converting DayOfWeek enum to a string repesenting the day
提问by James
I was wondering if there was a way to directly convert the integer DayOfWeekreturns into a string representing the day like Monday, Tuesday etc.
我想知道是否有一种方法可以将整数DayOfWeek返回值直接转换为表示星期一、星期二等日期的字符串。
Sample code:
示例代码：
MessageBox.Show(Date.Today.DayOfWeek)
This will return 6(as of today). Is there a way to directly convert this into Saturday, for example? I don't really care what it really converts it into, but I want to do away with my Select Case:
这将返回6（截至今天）。Saturday例如，有没有办法直接将其转换为 ？我真的不在乎它真正将它转换成什么，但我想取消我的 Select Case：
Select Case Date.Today.DayOfWeek
Case 0
day = "Sunday"
Case 1
day = "Monday"
Case 2
day = "Tuesday"
Case 3
day = "Wednesday"
Case 4
day = "Thursday"
Case 5
day = "Friday"
Case 6
day = "Saturday"
Case Else
day = "Apocalypse: we're all boned."
End Select
Thanks :)
谢谢 ：）

There's a DateTime format for that: dddd
有一个 DateTime 格式：dddd
Dim date1 As Date = #08/29/2008 7:27:15PM#
date1.ToString("dddd", CultureInfo.CreateSpecificCulture("en-US"))
With the CultureInfo you can get it in a specific language (it's optional)
使用 CultureInfo，您可以获得特定语言的信息（可选）

DateTime.DayOfWeekdoesn't return an integer - it returns an enum of type DayOfWeek. I'd expect that to be converted into the name automatically, but maybe this is a VB subtlety; maybe something to do with using Dateinstead of DateTime? Try this:
DateTime.DayOfWeek不返回整数 - 它返回类型的枚举DayOfWeek。我希望它会自动转换为名称，但也许这是 VB 的微妙之处；也许与使用Date而不是有关DateTime？尝试这个：
MessageBox.Show(DateTime.Today.DayOfWeek.ToString())
This won't be culture-sensitive though - it will always just display the name of enum value, in English. If that's not good for you, use Zyphrax or itowlson's solution.
但这不会是文化敏感的 - 它总是只显示枚举值的名称，英文。如果这对您不利，请使用 Zyphrax 或 itowlson 的解决方案。

Just in case others looked at this example. I believe it should be Case 0 for Sunday.
以防万一其他人看到这个例子。我相信周日应该是 Case 0。
Case 0
day = "Sunday"
