################################################################################ <# .SYNOPSIS Converts a PSCustomObject to a HashTable recursively. .DESCRIPTION This function converts a PSCustomObject and all its nested PSCustomObject properties into HashTables. It handles arrays and other collection types by processing each element recursively. .PARAMETER InputObject The PSCustomObject to convert into a HashTable. Accepts pipeline input. .EXAMPLE $object = [PSCustomObject]@{ Name = "John" Age = 30 Details = [PSCustomObject]@{ City = "New York" } } $hashTable = ConvertTo-HashTable -InputObject $object #> function ConvertTo-HashTable { [CmdletBinding(DefaultParameterSetName = "Default")] [OutputType([hashtable], [System.Collections.IEnumerable], [System.ValueType], [string])] param ( ######################################################################## [Parameter( Mandatory = $true, Position = 0, ValueFromPipeline = $true, ParameterSetName = "Default", HelpMessage = "The PSCustomObject to convert into a HashTable" )] [ValidateNotNull()] [object[]] $InputObject ######################################################################## ) begin { Write-Verbose "Starting PSCustomObject to HashTable conversion" } process { # return empty hashtable if input is null if ($null -eq $InputObject) { Write-Verbose "Input object is null, returning empty hashtable" return @{} } $InputObject | ForEach-Object { $currentObject = $_ # handle simple value types directly if ($currentObject -is [System.ValueType] -or $currentObject -is [string]) { Write-Verbose "Processing simple value: $currentObject" Write-Output $currentObject return } # create new hashtable for storing converted properties $resultTable = @{} # process each property of the current object foreach ($property in $currentObject.PSObject.Properties) { Write-Verbose "Processing property: $($property.Name)" # handle nested PSCustomObject properties if ($property.Value -is [System.Management.Automation.PSCustomObject]) { $resultTable[$property.Name] = ConvertTo-HashTable ` -InputObject $property.Value } # handle collection properties elseif ($property.Value -is [System.Collections.IEnumerable] -and $property.Value -isnot [string]) { $resultTable[$property.Name] = @( $property.Value | ForEach-Object { if ($_ -is [System.Management.Automation.PSCustomObject]) { ConvertTo-HashTable -InputObject $_ } else { $_ } } ) } # handle simple value properties else { $resultTable[$property.Name] = $property.Value } } Write-Output $resultTable } } end { Write-Verbose "Completed HashTable conversion" } } ################################################################################ |
