循环内的 Powershell 循环

【问题标题】：Powershell Loop within Loops循环内的 Powershell 循环

【问题描述】：

我有一个运行磁盘使用报告的 PowerShell 脚本（来自 http://gallery.technet.microsoft.com/Disk-Space-HTML-Email-f8b6bbfe）

我也在尝试将其更改为显示文件夹大小，但卡住了。我写了这个，效果很好：

$volName = "D:\"
$folders = (Get-ChildItem $volName | ?{ $_.PSIsContainer })
foreach ($folders in $folders)
{
$size = (get-childitem $folders.fullname -recurse | measure-object -property length -sum)
write-host $folders.fullname ($size.sum / 1MB)
}

但是当我尝试插入它时它并没有正确显示。这是我目前所拥有的：

它看起来像这样：

有人知道为什么文件夹名称和文件夹大小变量不起作用吗？

【问题讨论】：

    【解决方案1】：

    我认为问题（或问题之一）是这一行：foreach ($folders in $folders)。它应该是 foreach ($folder in $folders)，然后在 for 循环中您引用当前文件夹的任何地方都应该使用 $folder（而不是 $folders）。

    试一试，看看效果如何。

      【解决方案2】：

      感谢您的帮助，结果修改 $folder（并创建了一些其他）变量有效。包含文件夹和文件夹大小的报告：
