Discussed in https://github.com/jdhitsolutions/PSScriptTools/discussions/149

Originally posted by **scriptingstudio** June 8, 2024 Parameter `Property` makes the function more universal ```powershell param ( [Parameter(Position = 0, Mandatory, ValueFromPipeline)] [ValidateNotNullOrEmpty()] [object]$InputObject, [string[]]$Property ) ... # process block if ($Property) { foreach ($item in $InputObject) { $props = $item.PSObject.Properties.where{$_.name -in $Property} if (-not $props) {continue} if (-not $UniqueList.Exists({-not (Compare-Object $args[0].PSObject.properties.where{$_.name -in $Property}.value $props.value)})) { $UniqueList.add($item) } } } else { foreach ($item in $InputObject) { if (-not $UniqueList.Exists({-not (Compare-Object $args[0].PSObject.properties.value $item.PSObject.Properties.value)})) { $UniqueList.add($item) } } } ```

Using a property might also improve how this function handles more complex objects.

I have added this feature to v2.50.0 which has been published to the PowerShell Gallery.
