.SYNOPSIS Retrieves the localized string data based on the machine's culture. Falls back to en-US strings if the machine's culture is not supported. .PARAMETER ResourceName The name of the resource as it appears before '.strings.psd1' of the localized string file. For example: For WindowsOptionalFeature: MSFT_WindowsOptionalFeature For Service: MSFT_ServiceResource For Registry: MSFT_RegistryResource For Helper: SqlServerDscHelper .PARAMETER ScriptRoot Optional. The root path where to expect to find the culture folder. This is only needed for localization in helper modules. This should not normally be used for resources. .NOTES To be able to use localization in the helper function, this function must be first in the file, before Get-LocalizedData is used by itself to load localized data for this helper module (see directly after this function). #> function Get-LocalizedData { [CmdletBinding()] param ( [Parameter(Mandatory = $true)] [ValidateNotNullOrEmpty()] [System.String] $ResourceName, [Parameter()] [ValidateNotNullOrEmpty()] [System.String] $ScriptRoot ) if (-not $ScriptRoot) { $dscResourcesFolder = Join-Path -Path (Split-Path -Path (Split-Path -Path $PSScriptRoot -Parent) -Parent) -ChildPath 'DSCResources' $resourceDirectory = Join-Path -Path $dscResourcesFolder -ChildPath $ResourceName } else { $resourceDirectory = $ScriptRoot } $localizedStringFileLocation = Join-Path -Path $resourceDirectory -ChildPath $PSUICulture if (-not (Test-Path -Path $localizedStringFileLocation)) { #
