Combining arrays of objects that are linked

I have 3 arrays of objects. They look like this:

What I need to do is combine them into one array so I can write it to a CSV. The 3 need to be linked: File1ID and File2ID to the ID column in the other 2 arrays. I need to be able to pick what properties I want. Here's an example

$arr1[0] = {1,"c:\filename1.txt",1000....}
$arr1[1] = {2,"c:\filename2.txt",2000....}

$arrlink[0] = {1,2,"aaaa")

Desired Result:

newarray[0] = {"c:\filename1.txt", "c:\filename2.txt", "aaaa"}

I know I can foreach through and do this, but was wondering if there was a simpler/more direct way.

Of course, there are many items in each array, but they all link up in a 1 to 1 relationship.

I wound up using this. It saves a lot of typing and doesn't need to be modified if I modify the underlying objects (as long as I leave the linked fields alone).

$arrOutput = @()

foreach($a in $arrMatch)
    {
    $objOut = New-Object PsObject

    $a.psobject.properties | % { $objOut | Add-Member -MemberType $_.MemberType -Name $_.Name -Value $_.Value}
    $arrS1[$a.file1].psobject.properties | % { $objOut | Add-Member -MemberType $_.MemberType -Name ($_.Name + "_1")  -Value $_.Value}
    $arrS2[$a.file2].psobject.properties | % { $objOut | Add-Member -MemberType $_.MemberType -Name ($_.Name + "_2") -Value $_.Value}
    $arrOutput+= $objOut
    }
