while using arraylist how to display objects in powershell - powershell

Question

$result = New-Object System.Collections.ArrayList
ForEach ($repoElement in $Repo.value)
{
$repoId = $repoElement.id
$BranchCreatorUrl = "https://dev.azure.com/xyz/_apis/git/repositories/$repoId/refs?api-version=6.1-preview.1"
$CreateorInfo = (Invoke-RestMethod -Uri $BranchCreatorUrl -Method Get -UseDefaultCredential -Headers #{Authorization=("Basic {0}" -f $base64AuthInfo)})
$url1= "https://dev.azure.com/xyz/_apis/policy/configurations?api-version=4.1"
$response = (Invoke-RestMethod -Uri $url1 -Method Get -UseDefaultCredential -Headers #{Authorization=("Basic {0}" -f $base64AuthInfo)})
$obj=[pscustomobject]#{
RepositoryName = $repoElement.name
RepositoryId = $repoId
BranchName = $CreateorInfo.value.name
PolicyName = $response.value.type.displayname
}
$result += $obj
}
Write-Output $result
The above code gives an output
I want to show all the branch name as string and not in the form of object ie this way {..,...,...,..}

Answer 1

If this is just about for-display formatting, i.e. what is shown in the implicitly table-formatted display output, you can call Format-Table explicitly and use a calculated column to apply custom formatting to the BranchName column:
# Sample result.
$result = [pscustomobject]#{
RepositoryName = 'name'
RepositoryId = 'id'
BranchName = 'branch1', 'branch2', 'branch3'
PolicyName = 'policy'
}
# Use explicit Format-Table formatting with custom formatting of the
# 'BranchName' column.
$result | Format-Table RepositoryName,
RepositoryId,
#{ n='BranchName'; e={ $_.BranchName -join ', ' } },
PolicyName
The above yields a tabular display whose BranchName column doesn't have the enclosing { ... }, which PowerShell uses to indicate that the column value is an array (perhaps confusingly, because it looks like a script block):
RepositoryName RepositoryId BranchName PolicyName
-------------- ------------ ---------- ----------
name id branch1, branch2, branch3 policy
