Powershell Custom Object property order issue

September 22, 2022

When creating a custom object in powershell my properties are not ordering in the same precedence I type them in (top to bottom -> left to right).

I was told to use [ordered] on my table declaration as done below;

$AllMailData += New-Object PSObject -Property [ordered]@{
            'Unique ID' = $sharedmail.PrimarySmtpAddress
            'Display Name' = $sharedmail.DisplayName
        }

However this gives me a syntax error. Can anyone suggest where I have gone wrong?

>Solution :

You will get rid of the error when you enclose everything you’re passing to -Property in parenthesis ().

Also shorter way of writing this would be:

$AllMailData += [PSCustomObject]@{
            'Unique ID' = $sharedmail.PrimarySmtpAddress
            'Display Name' = $sharedmail.DisplayName
        }

[PSCustomObject] guarantees preservation of property order, where [PSObject] does not. But it seems that using ordered hashtable in your example accomplishes that, too.
