I am trying to retrieve an array and at the end I want to put all of them as a list into an hash, but I get only index and not the list of values.
$testArray = [System.Collections.ArrayList]@()
$tempArray = "123", "321", "453"
foreach($item in $tempArray) {
if ($item -notlike 123) {
$arrayID = $testArray.Add($item);
}
}
@{"mailboxes" = $arrayID};
As a result I would like to see values like
mailboxes {321, 453}
instead of index like below.
mailboxes 1
The ArrayList.Add() method returns the index of the new array element, so you are just adding an integer to $arrayID. Instead:
$testArray = [System.Collections.ArrayList]@()
$tempArray = "123", "321", "453"
foreach($item in $tempArray) {
if ($item -notlike 123) {
$testArray.Add($item);
}
}
@{ "mailboxes" = $testArray};
returns:
mailboxes {321, 453}
if you end goal is to get this
mailboxes {321, 453}
then you could do this
$OldArray = @("123", "321", "453")
[System.Collections.ArrayList]$NewArray = @()
foreach($item in $OldArray) {
if ($item -ne 123) {
$NewArray += item
}
}
@{"mailboxes" = $NewArray};
or just this...
@{"mailboxes" = @("123", "321", "453") | ? {$_ -ne 123}};
side note:
@() by default creates a [system.array] which are fixed in size. using += on a [system.array] will result in a new array being created and the old array contents will need to be copied into it.
[System.Collections.ArrayList] are dynamically size, they allow you to easily add new items.
@{"mailboxes" = $arrayID}->@{"mailboxes" = $testArray}
