Powershell GCI包含在arraylist中

Question

 $pdfs = @(gci $pioneerDest -Include $arrPDFName.Item(0), $arrPDFName.Item(0)  | foreach {write-output $_.name})

So I want to grab pdfs from a directory. However I only want the pdfs that will be the arraylist $arrPDFName . I cannot find a way to do this. Does anyone have any idea of using the powershell's collections with Get-ChildItem ?

Answer 1

Assuming something simple for your list like a list of file names you were on the right track.

-Include accepts arrays so there is not need to break it out. Just use it explicitly. In practice -include and -exclude work only when -Recurse is used. You can find a little more information on that from Get-ChildItem -Filter Array . Technet is also a good resource for this: Get-ChildItem

$arrPDFName = "text.txt","test.csv"
$pioneerDest = "c:\temp"
$pdfs = Get-ChildItem $pioneerDest -include $arrPDFName -Recurse | Select-Object -Expand Name

I removed the foreach-object loop since you were just using that to return properties. That is what Select-Object is for. You might also consider swapping out Name for FullName to get the full path.

Answer 2

Feed the list of names into gci through the pipeline, it will handle it.

$arrPDFName | gci

If they are actually full filenames in the current directory , and you know they all exist, that should be enough.

If they're not in the current directory, I'd be quite tempted to

$arrPDFName |% { "$pioneerDest\$_" } | gci

To loop over them and make them all full path names on the way into gci . Or cd $pioneerDest first.
