我正在创建一个菜单,其中一个选项是报告指定文件夹的文件夹大小并将其显示给用户.我输入文件夹名称后

cls
$Path = Read-Host -Prompt 'Please enter the folder name: '

$FolderItems = (Get-ChildItem $Path -recurse | Measure-Object -property length -sum)      

$FolderSize = "{0:N2}" -f ($FolderItems.sum / 1MB) + " MB"

我收到以下错误:

Measure-Object : The property "length" cannot be found in the input for any objects.

我正在制作一个脚本来设置本地主机上的IP,子网掩码,网关和DNS服务器地址.我有一个工作脚本,但我想确保输入的IP地址是数字字符,并且每个Octet的范围在0-255之间.任何帮助,将不胜感激.

     $IP = Read-Host -Prompt 'Please enter the Static IP Address.  Format 192.168.x.x'
                $MaskBits = 24 # This means subnet mask = 255.255.255.0
                $Gateway = Read-Host -Prompt 'Please enter the defaut gateway IP Address.  Format 192.168.x.x'
                $Dns = Read-Host -Prompt 'Please enter the DNS IP Address.  Format 192.168.x.x'
                $IPType = "IPv4"

            # Retrieve the network adapter that you want to configure
               $adapter = Get-NetAdapter | ? {$_.Status -eq "up"}

           # Remove any existing IP, gateway from our ipv4 adapter
