Hi all, I am trying to get this script to prompt for a language, can’t seem to get it to work.

$UserLanguageList = New-WinUserLanguageList -Language "en-US"
$UserLanguageList.Add=(Read-Host -Prompt "enter a language")
Set-WinUserLanguageList -LanguageList $UserLanguageList
I get the following error:
Exception setting “Add”: “Cannot set the Value property for PSMemberInfo object of type “System.Management.Automation.PSMethod”.”

At C:\Users\xscott\Desktop\ZAY\PS-BATCH and MDT Scripts\Untitled3.ps1:2 char:1
$UserLanguageList.Add=(Read-Host -Prompt “enter a language”)
CategoryInfo : NotSpecified: ( , SetValueInvocationException
FullyQualifiedErrorId : ExceptionWhenSetting
You can’t put the Read-Host expression within the .Add() method, because it expects a value rather than an expression that it can evaluation.
Try this:
$UserLanguageList = New-WinUserLanguageList -Language "en-US"
$AdditionalLanguage = Read-Host -Prompt "enter a language"
$UserLanguageList.Add($AdditionalLanguage)
Set-WinUserLanguageList -LanguageList $UserLanguageList
The language list is a sub-type of a List (T) class. Get-Member doesn’t list all of the available methods for list objects, but the documentation is here:

Thanks for teaching me to fish, worked like a charm. One more ask, when I run it, it prompts if I want to confirm (Continue with this operation). Is there a way to suppress that, or input a default response?
Usually that happens if a command specifies the -Confirm parameter. Does your script use it anywhere?You can stop the confirmation message by omitting the -Confirm parameter or explicitly by setting it to $false.
Set-WinUserLanguageList -LanguageList $UserLanguageList -Confirm:$false
You can also change value of the $ConfirmPreference preference variable.
