问题描述
我有一个运行磁盘使用情况报告的PowerShell脚本（从 http ：//gallery.technet.microsoft.com/Disk-Space-HTML-Email-f8b6bbfe ）
I have a PowerShell script that runs a disk usage report (From http://gallery.technet.microsoft.com/Disk-Space-HTML-Email-f8b6bbfe)
我试图将其更改为显示文件夹大小也是，但已经被卡住了。我写这个工作正常：
I'm trying to change it to display folder size as well, but have gotten stuck. I wrote this which works fine:
$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，它不会出来。这是我到目前为止：
But it doesn't come out right when I try to insert it. This is what I have so far:
# Script will generate Disk Space Report for Exchange Servers (Daily, Weekly, Monthly)
$ErrorActionPreference = "SilentlyContinue";
$scriptpath = $MyInvocation.MyCommand.Definition
$dir = Split-Path $scriptpath

$ReportSender = "blah@blah.com"
$users = "user1@mydomain.com", "user2@mydomain.com";
$MailSubject = "DiskSpace Report for $titledate"
#No change needed from here!!!

它出来看起来像这样：

任何人都知道为什么文件夹名称和文件夹大小变量isn'
Anyone know why the folder name and folder size variables aren't working?
推荐答案
我认为问题（或其中一个问题）是这一行： foreach （$文件夹中的$文件夹）。应该是 foreach（$文件夹中的$文件夹），然后在你所指向的当前文件夹的for循环中的任何地方应该使用 $ folder （不是 $ folders ）。
I think the problem (or one of the problems) is this line: foreach ($folders in $folders). It should be foreach ($folder in $folders) and then everywhere in the for loop that you refer to the current folder you should use $folder (not $folders).
尝试看看它的外观。
