Resize array

PowerShell Help
1

Hi there
I had the same problem long time ago and I cant remember what I did to solve it:(
basically I have an array of lets say 100 users(numbers might change, this is just for testing) which I need to “divide” to X number of “groups” and I want to then add each group members to a group for example(could be some other task).
so I import my big list:
$numbers= import-csv C:\files\out.csv
I the use this function to resize based on whatever size I want in this case 2 since I want 2 in each of the 50 groups:
function Resize-Array ([object]$InputObject, [int]$SplitSize = 100)
{
$length = $InputObject.Length
for ($Index = 0; $Index -lt $length; $Index += $SplitSize)
{
, ($InputObject[$index … ($index + $splitSize – 1)])
}
}
$resizedarray=Resize-Array -InputObject $numbers -SplitSize 50
$resizedarray.count
shows 50
now I want to cycle inside the $rezisedarray(which has 50 “groups”) and inside every “group” to add each of the members of that “group” to the ad group
but that doesn’t seem to work, so I tried write-host to see if I can even show these members and it doesn’t show them:
$resizedarray[0] |%{write-host $_.displayname}
user1
user2

and that shows the users just fine.

any ideas?

managed to solve the first problem
I was just referencing the wrong item
I should have used:
foreach($s in $resizedarray)
foreach ($i in $s){ Write-Host $i -ForegroundColor Green $group }
not
foreach ($i in $s){ Write-Host $i.displayname -ForegroundColor Green $group }

now I’m trying to combine it all including the 50 groups I have(adding each 2 mebers of the sub array($I) into a group of its own
like this:

foreach($s in $resizedarray) {
$groupid++
$Group=“Group{0:0}” -f $Groupid
foreach ($i in $s){ Write-Host $i -ForegroundColor Green $group }
}

but what I’m getting is:
user1 group220
user2 group220
user3 group221
user4 group221

for some reason it starts counting the group at 220 instead of at 1 like group1,group2,group3

any ideas why?

My guess is that you are using PowerShell’s ISE and the variable $groupid has been set by the first run of the script and incremented every time the script runs. Since it’s ISE the variable does not get cleared at the end of each run. It stays active in the active environment.

You could test running in a console powershell or just adding something like $groupid=0 before the foreach loop to initialize it back to 0.

you are absolutely right my friend
