代码放在code标签里面就可以了,比如:

如果您需要知道两个日期之间的间隔天数,那么可以用 New-TimeSpan 轻松地获得:- $startdate = Get-Date
- $enddate = Get-Date -Date '2014-09-12'
-
- $difference = New-TimeSpan -Start $startdate -End $enddate
- $difference.Days
复制代码 然而,如果您不仅想知道两者之间的间隔天数,而且还希望精确地获取每一天的日期对象,那么可以用这个方法:- $startdate = Get-Date
- $enddate = Get-Date -Date '2014-09-12'
-
- $difference = New-TimeSpan -Start $startdate -End $enddate
- $days = [Math]::Ceiling($difference.TotalDays)+1
-
- 1..$days | ForEach-Object {
- $startdate
- $startdate = $startdate.AddDays(1)
- }
复制代码 这一次,PowerShell 输出两个指定日期之间的所有日期对象。
当您了解了精确获取每个日期对象(而不仅是总天数)的方法之后,您可以过滤(例如以星期数),并查找距离您放假或退休之前还有多少个星期天或工作日。
以下代码是获取工作日用的:- $startdate = Get-Date
- $enddate = Get-Date -Date '2014-09-12'
-
- $difference = New-TimeSpan -Start $startdate -End $enddate
- $difference.Days
-
- $days = [Math]::Ceiling($difference.TotalDays)+1
-
- 1..$days | ForEach-Object {
- $startdate
- $startdate = $startdate.AddDays(1)
- } |
- Where-Object { $_.DayOfWeek -gt 0 -and $_.DayOfWeek -lt 6}
复制代码 这段代码时统计工作日天数用的:- $startdate = Get-Date
- $enddate = Get-Date -Date '2014-09-12'
-
- $difference = New-TimeSpan -Start $startdate -End $enddate
- "Days in all: " + $difference.Days
-
- $days = [Math]::Ceiling($difference.TotalDays)+1
-
- $workdays = 1..$days | ForEach-Object {
- $startdate
- $startdate = $startdate.AddDays(1)
- } |
- Where-Object { $_.DayOfWeek -gt 0 -and $_.DayOfWeek -lt 6} |
- Measure-Object |
- Select-Object -ExpandProperty Count
-
- "Workdays: $workdays"
