Question

我一直在编写一些PowerShell代码，它应该以XML格式收集和存储有关计算机的信息。但我似乎无法获得IP，MAC和网卡名称。

以下是我编写的一些代码示例（工作代码）：

#OSInfo
$newosinfo = (@($xml.computer.software.osinfo)[0])
Get-WmiObject -computer $compname Win32_OperatingSystem | 
ForEach-Object {
        $newosinfo = $newosinfo.clone() 
        $newosinfo.caption = $_.caption
        $newosinfo.serialnumber = [string]$_.serialnumber
        $newosinfo.OSArchitecture = $_.OSArchitecture
        $newosinfo.manufacturer = $_.manufacturer
        #Time $newosinfo.installdate;
        $xml.computer.software.AppendChild($newosinfo) > $null
}
$xml.computer.software.osinfo | where-object {$_.caption -eq ""} | foreach-object {$xml.computer.software.RemoveChild($_)}

这是我尝试编写的代码（不是代码）：

$newnetwork = (@($xml.computer.software.network)[0])
Get-WmiObject -computer $compname Win32_NetworkAdapter -Filter 'NetConnectionStatus=2' | 
ForEach-Object {
        $newnetwork = $newnetwork.clone()
        $newnetwork = 1 | Select-Object Name, MAC, IP 
        $newnetwork.Name = $_.Name
        $newnetwork.MAC = $_.MacAddress
        $IP = $_.GetRelated('Win32_NetworkAdapterConfiguration')
        $newnetwork.IP = $IP | Select-Object -expand IPAddress
        $xml.computer.software.AppendChild($newnetwork) > $null
}
$xml.computer.software.network | where-object {$_.Name -eq ""} | foreach-object {$xml.computer.software.RemoveChild($_)}

此代码提供此错误：

Cannot convert argument "0", with value: "@{Name=Intel(R) 82579V Gigabit Network Connect
ion; MAC=F4:6D:04:40:DB:6F; IP=10.0.0.12}", for "AppendChild" to type "System.Xml.XmlNod
e": "Cannot convert the "@{Name=Intel(R) 82579V Gigabit Network Connection; MAC=F4:6D:04
:40:DB:6F; IP=10.0.0.12}" value of type "Selected.System.Int32" to type "System.Xml.XmlN
ode"."
At A:\Dropbox\Bachelorprosjekt\Kode\Fungerende Script+kode\infoGatherer.ps1:177 char:43
+         $xml.computer.software.AppendChild <<<< ($newnetwork) > $null
    + CategoryInfo          : NotSpecified: (:) [], MethodException
    + FullyQualifiedErrorId : MethodArgumentConversionInvalidCastArgument

所以我的问题是，是否有人知道或可以编写如上所述的代码，这有效吗？顺便说一下：只收集有关“激活”卡片的信息是否更明智？

Answer 1

首先，我不确定为什么要将XmlNode包装在一个数组中，然后展开它 - 据我所知，以下两行是等效的：

$a = (@($xml.computer.software.network)[0])
$b = $xml.computer.software.network

我发现的第二件事，你有这个奇怪的1 | Select Name, MAC, IP，我猜你用它来尝试在你的XmlNode上填充这些属性？你实际在做的是将之前从XmlNode克隆的$ newnetwork对象更改为PSCustomObject类 - 当你尝试将它作为参数传递给appendChild（）方法时，它将会破坏。

以下是一些可以正常运行的PowerShell代码。我对您的XML结构做了一些假设，因此您可能需要对其进行调整以满足您的确切需求：

# setup sample XML
$xml = [xml]"
  <computer><software><network>
    <Name />
    <MAC />
    <IP />
  </network></software></computer>"

# duplicate network XmlNode and grab necessary info through WMI
# note: there may be more than one IP Address bound
#       on a given adapter. Use just the first one.
$info = $xml.computer.software.network.clone()
$nic = Get-WmiObject Win32_NetworkAdapter | select -first 1
$ip = $nic.GetRelated("Win32_NetworkAdapterConfiguration") | 
    select -expand IPAddress -first 1

# populate children with correct values
$info.Name = $nic.Name
$info.MAC = $nic.MACAddress
$info.IP = [string]($ip)

# finally append new XmlNode to software node
$xml.computer.software.appendChild($info)

Powershell：获取本地IP，MAC和网卡名称
