CSV 值被覆盖

Question

我一直在尝试将 import-csv 添加到来自 technet 的脚本中，以在 SharePoint Online 上创建子网站。最终结果将是由 CSV 制作子网站。例如。七年级，八年级。九年级。

我做了以下事情：

Import-Csv 'C:\sp\import.csv'|`
  ForEach-Object{
  $Urlsub = $_.Urlsub
  $Title = $_.Title
    }
$wci.Url = $Urlsub
$wci.Title = $Title

CSV：

Urlsub Title  
------ -----  
Year7 Year 7
Year8 Year 8

这仅适用于 CSV 中的最后一行。它似乎覆盖了最后一行留下的所有内容。

如果我将其更改为： $Urlsub += $_.Urlsub 它会将 $Urlsub 的所有列添加到同一个数组中。

如何在不覆盖之前值的情况下导入 CSV？

没有 csv 的完整脚本：

您最终得到最后一个值，因为您的变量赋值不在读取 CSV 文件的循环范围内。因此，您将获得变量设置的最后一项（CSV 的最后一行）。

我希望您需要为 csv 文件中的每一行创建 WebCreationInformation 实例，然后像我在本示例中尝试做的那样将每个实例添加到 $site.RootWeb.Webs。

Import-Csv 'C:\sp\import.csv' | ForEach-Object{
    $wci = New-Object Microsoft.SharePoint.Client.WebCreationInformation
    $wci.Url = $_.Urlsub
    $wci.Title = $_.Title
    $wci.UseSamePermissionsAsParentSite = $true
    $wci.WebTemplate = "{D0714A63-356A-4B73-815B-6E1DF824237F}#Template"
    $wci.Language = 1033
    $blogWeb = $site.RootWeb.Webs.Add($wci);
}
