# ------------------------------------------------------------------------------ # Function to compare hashtables content # ------------------------------------------------------------------------------ function Compare-Hashtable { <# .SYNOPSIS Compares hashtables content .DESCRIPTION Check that two given hashtables are identic. .PARAMETER Reference The Reference parameter should be the hashtable to check. .PARAMETER Difference The Difference parameter should be the hashtable against which to check the first one. .OUTPUTS Boolean. Compare-Hashtable returns a boolean depnding on the result of the comparison between the two hashtables. .EXAMPLE Compare-Hashtable -Reference $Hashtable1 -Difference $Hashtable2 #> [CmdletBinding ()] Param ( [Parameter ( Position = 1, Mandatory = $true, HelpMessage = "Reference hashtable" )] [ValidateNotNullOrEmpty ()] # [System.Collections.Specialized.OrderedDictionary] $Reference, [Parameter ( Position = 2, Mandatory = $true, HelpMessage = "Difference hashtable" )] [ValidateNotNullOrEmpty ()] # [System.Collections.Specialized.OrderedDictionary] $Difference ) Begin { # Get global preference variables Get-CallerPreference -Cmdlet $PSCmdlet -SessionState $ExecutionContext.SessionState # Variables $Check = $true } Process { # Check that hashtables are of the same size if ($Reference.Count -ne $Difference.Count) { $Check = $false } else { # Loop through tables foreach ($Key in $Reference.Keys) { # Check that they contain the same keys if ($Difference.$Key) { # Check that they contain the same values if ($Difference.$Key -ne $Reference.$Key) { $Check = $false Write-Log -Type "DEBUG" -Message "$($Difference.$Key) does not exists in reference hashtable" break } } else { $Check = $false Write-Log -Type "DEBUG" -Message "$Key does not exists in difference hashtable" break } } } return $Check } } |
