Trying to list Datastores that are not in a list of folders.

I am stuck, What I would like to do is exclude datastores within a list of datastore folders when getting a list of datastores.

if I do a get-folder, I get the following (which is expected):

Name                           Type         

----                           ----         

datastore                      Datastore    

New_Folder                     Datastore    

Internal_Datastores            Datastore

I'd like to list out just the datastores in the datastore folder and not the New_Folder and Internal_Datastores folders.

The following works:

$datastore_folder_exclude = @("datastore")      #list out the datastore folders to exclude from the report

$ds_fold_exclude = $datastore_folder_exclude.ForEach({ [RegEx]::Escape($_) }) -join '|'    #creates a regular expression based on $datastore_folder_exclude variable

$folder = get-folder -type Datastore| where-object {$_.name -notlike $ds_fold_exclude}

foreach ($fold in $folder){get-datastore -location $fold.name}

This lists out the datastores that are in the New_Folder and Internal_Datastores folders.

What I want to do is the opposite though, excluding these two folders.

What  I came up with is:

$datastore_folder_exclude = @("New_Folder","Internal_Datastores")      #list out the datastore folders to exclude from the report

$ds_fold_exclude = $datastore_folder_exclude.ForEach({ [RegEx]::Escape($_) }) -join '|'    #creates a regular expression based on $datastore_folder_exclude variable

$folder = get-folder -type Datastore| where-object {$_.name -notlike $ds_fold_exclude}

foreach ($fold in $folder){get-datastore -location $fold.name}

This does not work, it returns all datastores.  actually duplicating the datastores that are IN the folders that I'm attempting to exclude.
