Powershell Remove "Limited Access"

对于有多级web获取getlist会报错：Exception calling “GetList” with “1” argument

$SPWeb = Get-SPWeb -Identity http://192.168.0.50:81/oasite/
#注意getlist的写法
$list = $SPWeb.GetList("/oasite/Lists/Facilities and Shared Assets")
$item = $list.Items| where{ $_.Name -eq "北京10F第五会议室"}

$return = $item.RoleAssignments |where {$_.RoleDefinitionBindings -eq $SPWeb.RoleDefinitions["受限访问"]};

foreach ($i in $return)
{
    Write-Host "Removing: " $i.Member;
    $item.RoleAssignments.Remove($i.Member);
}

 断开权限继承

$SPWeb = Get-SPWeb -Identity http://192.168.0.50:81/oasite/
$list = $SPWeb.GetList("/oasite/Lists/Facilities and Shared Assets")

$item = $list.Items| where{ $_.Name -eq "北京10F第五会议室"}
$item.BreakRoleInheritance(true)

$return = $item.RoleAssignments |where {$_.RoleDefinitionBindings -eq $SPWeb.RoleDefinitions["受限访问"]};

foreach ($i in $return)
{
    Write-Host "Removing: " $i.Member;
    $item.RoleAssignments.Remove($i.Member);
}
