It doesn't actually return an object representing a registry key's value, but some other weird object that requires painful gyrations to get values from. This function returns just the value of a key. .EXAMPLE Get-RegistryKeyValue -Path 'hklm:\Software\Carbon\Test' -Name 'Title' Returns the value of the 'hklm:\Software\Carbon\Test' key's `Title` value. #> [CmdletBinding()] param( [Parameter(Mandatory=$true)] [string] # The path to the registry key where the value should be set. Will be created if it doesn't exist. $Path, [Parameter(Mandatory=$true)] [string] # The name of the value being set. $Name ) Set-StrictMode -Version 'Latest' Use-CallerPreference -Cmdlet $PSCmdlet -Session $ExecutionContext.SessionState if( -not (Test-RegistryKeyValue -Path $Path -Name $Name) ) { return $null } $itemProperties = Get-ItemProperty -Path $Path -Name * $value = $itemProperties.$Name Write-Debug -Message ('[{0}@{1}: {2} -is {3}' -f $Path,$Name,$value,$value.GetType()) return $value } |
