中使用PowerShell＆QUOT;其中＆QUOT;命令来比较值的数组 [英] Using Powershell "where" command to compare against Array of values

问题描述

我试图找出一种方式来获得该命令从值的数组来过滤，而不是一个值。目前，这是我的code是如何（和它的作品当$ ExcludeVerA是一个值）：

I'm trying to figure out a way to get this command to filter from an array of values as opposed to one value. Currently this is how my code is (and it works when $ExcludeVerA is one value):

$ExcludeVerA = "7"

$java = Get-WmiObject -Class win32_product | where { $_.Name -like "*Java*"} |
where ({ $_.Version -notlike "$ExcludeVerA*" })

和我想$ ExcludeVerA有像这样值的数组（这个目前不工作）：

And I'd like $ExcludeVerA to have an array of values like so (this currently doesn't work):

$ExcludeVerA = "7", "3", "4"

foreach ($x in $ExcludeVerA)
{

$java = Get-WmiObject -Class win32_product | where { $_.Name -like "*Java*"} |
where ({ $_.Version -notlike "$ExcludeVerA*" })

}

什么我可以做的，为什么code的第二块不起作用任何意见或其他的想法？

Any ideas of why this second block of code doesn't work or other ideas of what I can do?

推荐答案

尝试 -notcontains

where ({ $ExcludeVerA -notcontains $_.Version })

所以，如果我的理解corretly，然后

so if I understand it corretly, then

$ExcludeVerA = "7", "3", "4"

$java = Get-WmiObject -Class win32_product | where { $_.Name -like "*Java*"} |
where ({ $ExcludeVerA -notcontains $_.Version })

这是直接回答你的问题。可能的解决办法是这样的：

That was direct answer to your question. Possible solution might be something like this:

$ExcludeVerA = "^(7|3|4)\."
$java = Get-WmiObject -Class win32_product | 
          where { $_.Name -like "*Java*"} |
          where { $_.Version -notmatch $ExcludeVerA}

使用它来获得完成工作正则表达式。

it uses regex to get job done.
