Filter Get-ChildItem by an array

Question 1

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*"
                );

$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}
}

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  }

1 2	Get-ChildItem $sourceDir \| Where-Object { $matchPattern -contains $_.Name }

Question 2

You can just do:

gci "$someDir\*" -include $matchPattern

1 2	gci "$someDir\*" -include $matchPattern
