使用Powershell如何获得工作日数? [英] Using Powershell how do you get the weekday number?

问题描述

使用 Powershell 日期对象如何获取星期几，0 到 6，其中 0 表示星期日，6 表示星期六.我知道我可以使用下面的代码获取日期名称，但是由于没有 DayNumberOfWeek 或等效属性，我如何获取数字?

Using a Powershell date object how do you get the day number of the week, 0 to 6 where 0 would be Sunday and 6 would be Saturday. I know that I can get the day name with the code below but how do I get the number as there is no DayNumberOfWeek or equivalent property?

(Get-Date).DayOfWeek

我想我可以在 switch 语句中使用上面代码中的日期名称将其转换为数字，但这似乎不是很有说服力.

I suppose I could use the day name from the code above in a switch statement to convert it to a number but that doesn't seem to be very eloquent.

推荐答案

像这样:

( get-date ).DayOfWeek.value__

我建议将来以这种方式调查对象的哪些属性:

I suggest for the future to investigate what properties an object in this way:

( get-date ).DayOfWeek | gm -f # gm is an alias for get-member
