使用Powershell CSOM为Sharepoint组的列表添加只读权限 [英] Adding Read-Only-permissions to a list for a Sharepoint Group using Powershell CSOM

问题描述

我正在尝试为名为学生的特定组添加只读权限，以便创建名为测验的列表。我必须使用PowerShell CSOM，在我经历的其他每个教程中，都使用了.NET服务器类型。



代码：

I am trying to add read-only-permissions to a specific group called "Students" for a list I have created called "Quiz". I have to use PowerShell CSOM, and in every other tutorial I've been through, .NET server types have been used.

Code:

$ListName = "Quiz"
$PermissionLevel = "Read Only"
$web = $ctx.Web

$lists = $web.Lists
$ctx.Load($lists)
$ctx.ExecuteQuery()
foreach($list in $lists)
{
    if($list.Title -eq $ListName)
    {
        $listId = $list.Id
    }
}
$list = $lists.GetById($listId)
$ctx.Load($list);
$ctx.ExecuteQuery();

Write-Host "List:" $List.Title -foregroundcolor Green
if ($list -ne $null)
{
    $groups = $web.SiteGroups
    $ctx.Load($groups)
    $ctx.ExecuteQuery()
    foreach ($SiteGroup in $groups) {
        if ($SiteGroup.Title -match "Students")
        {
            write-host "Group:" $SiteGroup.Title -foregroundcolor Green
            $GroupName = $SiteGroup.Title

            $builtInRole = $ctx.Web.RoleDefinitions.GetByName($PermissionLevel)

            $roleAssignment = new-object Microsoft.SharePoint.Client.RoleAssignment($SiteGroup)
            $roleAssignment.Add($builtInRole)

            $list.BreakRoleInheritance($True, $False)
            $list.RoleAssignments.Add($roleAssignment)
            $list.Update();
            Write-Host "Successfully added <$GroupName> to the <$ListName> list in <$site>. " -foregroundcolor Green
        }
        else
        {
                Write-Host "No Students groups exist." -foregroundcolor Red
        }
    }
}

我的错误在

My error is in

$roleAssignment = new-object Microsoft.SharePoint.Client.RoleAssignment($SiteGroup)

，我收到错误

, where I'm recieving the error

Cannot find an overload for "RoleAssignment" and the argument coun
t: "1".

大部分教程使用

Most tutorials use

$roleAssignment = new-object Microsoft.SharePoint.SPRoleAssignment($SiteGroup)

我不能使用。



如何填写我的代码？



PS我知道我的代码有点乱，但我花了太多时间试图找到解决方案，而且我的代码在过去几小时内质量大大降低。对不起。

which I CAN NOT USE.

How can I complete my code?

P.S. I know my code is a bit messy, but I've been spending too much time trying to find a solution, and my code has greatly reduced in quality over the past hours. Sorry for that.

推荐答案

ListName = 测验

ListName = "Quiz"

PermissionLevel = 只读

PermissionLevel = "Read Only"

web =
