string - 在PowerShell中将System.Object []导出为字符串

Question

我创建了一个脚本，该脚本基本上会遍历站点及其子站点中的所有列表，并列出每个文档或项目的权限。

该脚本有效，但是，当写入CSV文件时，权限(成员+角色)字符串将被写入System.Object[]而不是CSV输出中的正确字符串(例如Member: user123 Role: Full Control)。

样本输出:

"Common Hover Panel Actions", "https://#######.####.###.##", "https://######.######.#####.####", "System.Object[]", "                           Ministry for Finance", "Master Page Gallery", "12/22/2015 8:34:39 AM", "_catalogs/masterpage/Display Templates/Search/Item_CommonHoverPanel_Actions.js", "12/22/2015 8:34:39 AM", "6.2763671875"

下面是脚本:

Add-PSSnapin Microsoft.SharePoint.PowerShell

function Get-DocInventory([string]$siteUrl) {
    $site = New-Object Microsoft.SharePoint.SPSite $siteUrl

    $i = 0;
    foreach ($web in $site.AllWebs) {

        $count = $site.AllWebs.Count
        foreach ($list in $web.Lists) {

            if ($list.BaseType -ne “DocumentLibrary”)
            {
               continue
            }

            foreach ($item in $list.Items) {
                $data = @{
                    "Web Application" = $web.ToString()
                    "Site" = $site.Url
                    "Web" = $web.Url
                    "list" = $list.Title
                    "Item URL" = $item.Url
                    "Item Title" = $item["Title"]
                    "Item Created" = $item["Created"]
                    "Item Modified" = $item["Modified"]
                    "File Size" = $item.File.Length/1KB
                    "Permissions" = foreach($roleAssignment in $item.RoleAssignments)
                    {
                        $Permission = ""

                        foreach($roleDefinition in $roleAssignment.RoleDefinitionBindings)
                        {
                            $Permission = $(foreach($roleAssignment in $item.RoleAssignments){$roleAssignment}
                            {
                                "Member: " +  $roleAssignment.Member.LoginName + " Role: " + $roleDefinition.Name + " "
                            } -join ',')

                            $Permission
                            Write-Progress -activity "Working" -status "Checked Sub-Site $i of $count" -percentComplete (($i / $count)/100)
                        }
                    }
                }
                New-Object PSObject -Property $data
            }
        }
        $web.Dispose();
    }
    $i++
    $site.Dispose()
}
<# Get-DocInventory "https://#####.####.###.##/" | Out-GridView #>
Get-DocInventory "https://#####.####.###.##/" | Export-Csv -NoTypeInformation -Path C:\Users\livob002-lap\Desktop\Permissions-FinanceIntranet.csv

是否可以将用户名的System.Object []导出为CSV中的字符串？名称在GridView中应有的显示。

Answer 1

foreach语句返回一个数组，因此该行

"Permissions" = foreach($roleAssignment in $item.RoleAssignments)

将System.Array分配给键“Permissions”。 System.Array的ToString()方法返回System.Object []。

您可以使用-join运算符将字符串数组“转换”为字符串。以下可能有效。

"Permissions" = foreach($roleAssignment in $item.RoleAssignments)
{
    ...
} -join ', '
