How to count the result of a if loop within foreach loop

问题

Is there a better way to be able to count the amounts of empty groups than using this method and then calling $count + 1 for each result? I tried to mess around with $123.count but it kept returning 0

$Groups = Get-ADGroup -Properties * -Filter * | where { $_.Members.Count -eq 0}
$123= Foreach($G In $Groups)
{
    $Membership = Get-ADGroupMember -Identity $G.Name
    If($Membership.count -eq 0){
    $Count = $count + 1
    }

}

回答1:

Get-ADGroup can do much of what you ask without going away from AD.

Getting this done with the Filter parameter is painful. The LDAP filter however is simple.

For empty groups:

Get-ADGroup -LdapFilter "(!member=*)"

For empty groups which are also not nested inside other groups:

Get-ADGroup -LdapFilter "(&(!memberOf=*)(!member=*))"
