Researching the optimal; implementing the practical

Karl Prosser posts a PowerShell script quick and dirty new custom object as a way to create PowerShell objects on the fly. I’ve come across the need for this and posted an approach PowerShell Function Factory after reading up on Managing Records in Python.

Yet Another Approach To Building Custom Objects

This function peels off two items at a time placing them in $key and $value, $list gets the remainder (it has two fewer items now). Then key/value pair is added to the $Properties hash table. The while loop continues until $list is empty.

After the $Properties hash table is built up, a new PSObject is returned with those properties created and populated by using the –Property parameter on New-Object.

Function New-PSCustomObject ($list) {
    $Properties = @{}            

    while($list) {
        $key, $value, $list = $list
        $Properties.$key = $value
    }            

    New-Object PSObject -Property $Properties
}            

Function ql {$args}            

New-PSCustomObject ( ql Name "John Doe" Age 10 Height (6*12) )

Result

Still rolling this around in my head. Love to hear other approaches. Plus, this may show up in PowerShell Version 3.

UPDATE

Thanks to Nivot Ink for a terser approach.

while($key, $value, $list = $list) {
    $Properties.$key = $value
}
