从所有安全组Powershell中删除所有权限

Question

I need to remove all the permissions in sharepoint to all security groups in Powershell.

First, I'm trying to do this in all groups and here's my code:

    $groups = $root.SiteGroups
    foreach($group in $groups)
    {

    }

I only found the way to add with roles like this, but I want to remove all.

  $spRoleAssignment = New-Object Microsoft.SharePoint.SPRoleAssignment($spGroup)
               $sproledefinition = $web.RoleDefinitions["Contribute"]
               $sproleassignment.RoleDefinitionBindings.Add($sproledefinition)

thanks in advance.

Answer 1

您可以使用RemoveAll()从SPRoleAssignment中删除所有RoleDefinitionBindings ：

$sproleassignment.RoleDefinitionBindings.RemoveAll()
