Powershell从共享点中的特定组中删除用户

问题描述：

我试图从共享点中删除特定用户并且撞到了墙上。Powershell从共享点中的特定组中删除用户

我不断收到以下错误

You cannot call a method on a null-valued expression.

代码：

function verifyUsers 
{ 
    $verify_sitepath="https://extranet.mydomain.com" 
    $verify_site=new-object Microsoft.SharePoint.SPSite($verify_sitepath) 
    $verify_web=$verify_site.Rootweb 
    $verify_web.site.url 
    $verify_groups = $verify_web.groups | ? {$_.Name -match "^.*$CurrentGroup" } 
    foreach($verify_group in $verify_groups) 
    { 
     #Write-Output "+ $($verify_group.Name)" 
     foreach($verify_user in $verify_group.users) 
     { 
      $verify_user = $verify_user -replace "MYDOM\\","" 
      Write-Output "$verify_user" | Out-File -filepath "$splist$currentGroup.txt" -append 
     } 
    } 
    $strReference = get-Content "C:\Powershell\Users from SharePoint\$currentgroup.txt" 
    $strDifference = get-Content "C:\Powershell\Users in groups\$currentgroup.txt" 
    Compare-Object $strReference $strDifference 

    Compare-Object $strReference $strDifference | ` 
    Where-Object { $_.SideIndicator -eq "<=" } | ` 
    ForEach-Object { 
     if ($_.InputObject -eq "testuser ") 
     { 
      Write-Host "testuser HAHAHAHAHA" 
      $TheNewGroup = $OpenWeb.SiteGroups | Where-Object {($_.Name -match $currentGroup)} 
      "group Name: $TheNewGroup.Name" 
      #$TheNewGroup.deleteuser("MYDOM\" + $_.InputObject) 
      #$web.Update() 

      $TheNewGroup.SiteUsers.Remove("MYDOM\testuser ") 
     } 
     Write-Host $_.InputObject 
     "Deleting user: {0} from $currentgroup" -f $_.InputObject 
    } 
}

答

发现的anwser（对不起我上面的乱码）

$theuser = $verify_web.AllUsers.Item("MYDOM\testuser") 
$TheNewGroup.RemoveUser($theuser)

答

嗯，有多种方式从SharePoint网站集中删除用户：

您可以删除使用SharePoint Web界面的用户
从SharePoint网站删除用户使用PowerShell（散装也删除可能）
编程方式使用C＃在SharePointDiary
