ジェイミーの答えはあなたの特定の問題にぴったりでしたが、メンバーから複数のプロパティを取得する必要があります. コードを変更せずにこの問題に対処できることがわかりました。コードを呼び出すInvoke前GetTypeに、コードを呼び出しますInvokeMember。()以下のコードでは、GetType の後にそれがないことに注意してください。
$obj_group = [ADSI]"WinNT://localhost/Administrators,group"
$members=@($obj_group.Invoke("Members"))|foreach{$_.GetType.Invoke().InvokeMember("Name","GetProperty",$null,$_,$null)}
Write-Output "Current local Administrators: $members"
これは、グループ メンバーに関する詳細情報を提供する私のユース ケースです。これには、Resolve-DNS コマンドを使用するため、PowerShell 4.0 が必要です。
function Get-LocalGroupMembers {
<#
.Synopsis
Get the group membership of a local group on the local or a remote computer
.EXAMPLE
Defaults to collecting the members of the local Administrators group
PS C:\> Get-LocalGroupMembers | ft -AutoSize
ComputerName ParentGroup Nesting Name Domain Class
------------ ----------- ------- ---- ------ -----
EricsComputer 0 Administrator EricsComp User
EricsComputer 0 eric EricsComp User
EricsComputer 0 Domain Admins DomainName Group
.EXAMPLE
Query a remote computer (that is known not to respond to a ping) and a targeted group
PS C:\> Get-LocalGroupMembers -computerName EricsComputer -localgroupName Users -pingToEstablishUpDown $false
ComputerName ParentGroup Nesting Name Domain Class
------------ ----------- ------- ---- ------ -----
EricsComputer 0 SomeOtherGuy EricsComp User
.NOTES
The ParentGroup and Nesting attributes in the output are present to allow
the output of this function to be combined with the output of
Get-ADNestedGroupMembers. They serve no purpose otherwise.
