I've been trying to figure out how to count all elements in an multidimensional array. But .Count only returns the first dimension.

after i gave up to find a proper solution i just created this loop to move all elements to the first dimension and count them. but this is really only a hack.

$mdarr = @((0,1,2,3,4),(5,6,7,8,9),(10,11,12,13,14))

$filecount = New-Object System.Collections.ArrayList

for($i = 0; $i -lt $mdarr.Length; ++$i) {

        $filecount += $mdarr[$i]

}

$filecount.Count

How would this be done properly without processing the array first?

In the loop you are adding the elements of $mdarr[$i]. You later count the elements of the merge result. Instead of the adding to an ArrayList you could keep a count:

$xs = @((0,1,2,3,4),(5,6,7,8,9),(10,11,12,13,14))

$sum = 0;

foreach ($x in $xs) { $sum += $x.Count }

$sum  // 15



# alternatively

$xs | % { $sum += $_.Count }



# or

($xs | % { $_.Count } | Measure-Object -Sum).Sum

# or

$xs | % { $_.Count } | Measure-Object -Sum | select -Expand Sum
