Format-Table for array of hashtables - powershell

Question

I am trying to use the Format-Table command to output an array of hash tables of all files checked out from our TFS repo.
My code thus far:
$arr = #();
#Take the string from the tf command, parse it and build an array of hash tables
(tf stat /recursive /user:* /format:detailed | Select-String -Pattern '^\$' -NotMatch | Select -SkipLast 3 | Out-String) -split '(\r\n){2}' | ForEach-Object {
$ht = #{};
if ($_ -ne '') {
$str = $_ | Out-String;
$str -split '\r?\n'| ForEach-Object {
$key, $value = $_ -split '\s*:\s*';
#Write-Host $key, $Value;
try {
$ht.Add($key, $value);
} catch [ArgumentException] {
Write-Host "Caught exception";
}
}
$arr += ($ht);
}
}
Edit
Looks like I'm erroring out here.
$arr.ForEach({[PSCustomObject]$_}) | Format-Table -AutoSize
Full Error:
Cannot convert value "System.Collections.Hashtable" to type
"System.Management.Automation.LanguagePrimitives+InternalPSCustomObject". Error: "Cannot process argument because the
value of argument "name" is not valid. Change the value of the "name" argument and run the operation again."
At C:\Dev\Tools\powershell\Convert-TfsOutput.ps1:21 char:15
+ $arr.ForEach({[PSCustomObject]$_}) | Format-Table -AutoSize
+ ~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [], RuntimeException
+ FullyQualifiedErrorId : InvalidCastConstructorException
Edit2
Here is sample output when i replace the above line with:
$arr.ForEach({ $_ | Out-String })
Name Value
---- -----
Workspace work1
Date {Wednesday, September 5, 2018 1, 38, 48 PM}
Local item file1
File type Windows-1252
User user1
Lock none
Change edit
Name Value
---- -----
Workspace work2
Date {Monday, September 10, 2018 12, 14, 56 PM}
Local item file2
User user2
Lock none
Change edit
Edit 3
Output of the below command
Write-Host $str;
User : User1
Date : Wednesday, September 5, 2018 1:38:48 PM
Lock : none
Change : edit
Workspace : Work1
Local item : File1
File type : Windows-1252
User : User2
Date : Monday, September 10, 2018 12:14:56 PM
Lock : none
Change : edit
Workspace : Work2
Local item : File2
Would like the output in a tabular format with rows below the column names:
Workspace | Date | Local item | File type | User | Lock | Change
Tried to use the code in another answer but it does not output correctly.
Format-Table on Array of Hash Tables

Answer 1

Convert your hashtables to custom objects before passing them to Format-Table.
... | Where-Object { $_ } | ForEach-Object {
$ht = #{};
($_ | Out-String) -split '\r?\n'| ForEach-Object {
...
}
New-Object -Type PSObject -Property $ht
} | Format-Table
Edit: Looks like your input data has blank lines which lead to keys with empty strings in your hashtables, which then cause the error you observed, because objects can't have a property with an empty string for a name.
Change your hashtable/object creation to something like this:
... | Where-Object { $_ } | ForEach-Object {
$ht = ($_ | Out-String).Trim() -replace '\s+:\s+', '=' |
ConvertFrom-StringData
New-Object -Type PSObject -Property $ht
} | Format-Table
