pscustomobject multiple lines per row - powershell

Question

I have some code so far, but would like it to result in a table with multiple lines for users per group.
Currently, it creates a table like this:
Group
Users
abcgroup1
Alice
abcgroup1
Bob
abcgroup2
Bob
abcgroup2
Jason
abcgroup3
Eve
I would like it to instead create a table like this:
Group
Users
abcgroup1
AliceBob
abcgroup2
BobJason
abcgroup3
Eve
$Groups = get-adgroup -Filter 'name -like "*abc*"'
$Results = foreach( $Group in $Groups ){
Get-ADGroupMember -Identity $Group | foreach {
[pscustomobject]#{
Group = $Group.Name
Users = $_.Name
}
}
}
$Results
$Results | Export-Csv C:\abc_search.txt -NoTypeInformation

Answer 1

You can use -join operator concatenating by CRLF `r`n. This will result in a multiline string:
$Groups = Get-ADGroup -Filter "name -like '*abc*'"
$Results = foreach($Group in $Groups)
{
[pscustomobject]#{
Group = $Group.Name
Members = (Get-ADGroupMember -Identity $Group).Name -join "`r`n"
}
}
$Results | Format-Table -Wrap -Autosize
$Results | Export-Csv C:\abc_search.csv -NoTypeInformation
Note that I'm using -Wrap on Format-Table, needed to correctly display multiline strings on the console.
The other option you could use is Out-String thought that would also require the use of .TrimEnd() method to get rid of the trailing new line:
Members = ((Get-ADGroupMember -Identity $Group).Name | Out-String).TrimEnd()
