Filter Get-ChildItem by an array

I have just started using PowerShell today, and I have an intention list files by a few patterns in an array, for instance:

$matchPattern = (
                  "SomeCompany.SaaS.Core.Mvc*",
                  "SomeCompany.SaaS.Core.UI.Framework*"
                );

I want to list files in a $sourceDir where any of the item in the above array matches.

I can do this, and it works:

foreach ($item in $matchPattern)
{
    Get-ChildItem $sourceDir | Where-Object {$_.Name -like $item}
}

Just for learning purposes, can I do it in pipe-lining?

Something similar to this:

Get-ChildItem $sourceDir | Where-Object { $matchPattern -contains $_.Name  }

You can just do:

gci "$someDir\*" -include $matchPattern

Something like this should work.

Assuming an array $a exists with some strings in it:

gci $someDir | %{$a -eq $_.name}

Whenever the name of the directory found by gci matches a value in the $a array, it will echo out that value. So if $someDir=C:\ and "windows" was an element in $a, the output would be just "windows" if it was the only match.

Edit: My mistake, I did not realize you wanted the * as a wildcard and not a literal, this only matches literals. Solved below.

For pattern matches, you can use regex arrays. Define one like so

[regex]$patt = “^(Win.*|.*Files)$”

You can now compare all matches like the above

gci $someDir | ?{$_.name -match $patt}
