在PowerShell中,如果我有一个包含版本信息的字符串列表,如“3.0.1.1”,“3.2.1.1”等,我应该如何对其进行排序,以便与C#中的System.Version相同?
PS C:\> $ver="3.0.1.1","3.2.1.1"
PS C:\> $ver|%{[System.Version]$_}|sort
Major Minor Build Revision
----- ----- ----- --------
3 0 1 1
3 2 1 1
将其转换为版本并按此方式排序:
$list = "3.0.1.1","3.2.1.1"
$sorted = $list | %{ new-object System.Version ($_) } | sort
sort-object
可以传递一个脚本块并对结果进行排序。PS C:\Users\me> "3.11.0.1", "3.0.1.1", "3.2.1.1" | sort
3.0.1.1
3.11.0.1
3.2.1.1
PS C:\Users\me> "3.11.0.1", "3.0.1.1", "3.2.1.1" | sort {[version] $_}
3.0.1.1
3.2.1.1
3.11.0.1
# I needed to sort historical versions (Octopus) with varying decimal formats.
# Try # this (it is easy to add to a more complex expression sort)
# Special Case "3.00.1.10.1.10" and "3.0.1.10.1.10" required the double sort
# to work correctly
$vers = @()`enter code here`
$vers += @( "3.1.60", "3.1.52","3.1.51")
$vers += @( "3.00.46", "3.00.36","3.50.2145.11")
$vers += @( "3.50.2145.10","3.50.2145.9")

$vers += @( "3.0.1.10.1.100","3.0.1.10.1.10")
$mySortAsc = @{Expression={ [regex]::Replace($_ ,'\d+', { $args[0].Value.PadLeft(20,'0') }) };Descending=$false}

$nl = [Environment]::NewLine
Write-Output ($nl + "Ascending Sort" + $nl);
$vers | Sort-Object | Sort-Object $mySortAsc
Write-Output ($nl + "Descending Sort" + $nl);
$vers | Sort-Object -Descending | Sort-Object $mySortDesc
