Powershell, Tying 2 variables together in one script

Question

I have the following script. It is getting me a system array. I need to tie the $id variable and the $upn variable together with each iteration. I am at a loss on how to get the loop to continue through and tie the 2 variables together. Any help would be appreciated.

$adroles = get-mgdirectoryrole | select displayname,Id
$upn = foreach ($id in $adroles.id) { 
    Get-mgdirectoryrolemember -DirectoryRoleId $id | 
        select-object -expandproperty additionalproperties |
            foreach-object -membername userPrincipalName
}
}

I believe you're looking to merge the output from Get-MgDirectoryRole with the output from Get-MgDirectoryRoleMember, if that's the case this is how you can do it:

Get-MgDirectoryRole | ForEach-Object {
    foreach($upn in (Get-MgDirectoryRoleMember -DirectoryRoleId $_.Id).additionalProperties.userPrincipalName) {
        [pscustomobject]@{
            DisplayName       = $_.DisplayName
            Id                = $_.Id
            UserPrincipalName = $upn
        }
    }
}

There is another way to get this information in a single API call by using the $expand parameter on the members relationship:

$uri = 'v1.0/directoryRoles?$expand=members&$select=displayName'

do {
    $response = Invoke-MgGraphRequest GET $uri
    $uri = $response.'@odata.nextLink'

    foreach ($role in $response.value) {
        foreach ($member in $role.members) {
            [pscustomobject]@{
                RoleId                  = $role['id']
                RoleDisplayName         = $role['displayName']
                MemberUserPrincipalName = $member['userPrincipalName']
                MemberDisplayName       = $member['displayName']
                MemberType              = $member['@odata.type'].Split('.')[-1]
            }
        }
    }
}
while ($uri)
