Powershell 使用CSV文件和Mac地址重命名计算机

我正在尝试设置一个主CSV文件，当PowerShell脚本在MDT任务序列期间运行时，该文件将被检查。脚本试图做的是获取物理连接的nic卡的mac地址，并将其与CSV文件进行比较，以查看它是否与文件中保存的mac地址匹配。如果mac地址与CSV中的值匹配，则会将计算机重命名为与mac地址配对的值。如果没有匹配项，请根据计算机序列号重命名

这是我目前所拥有的

$computer = Get-WmiObject Win32_ComputerSystem -ComputerName $oldname
#$Machost is Mac Address of the active Network Card
$MacHost=Get-NetAdapter -Name "Ethernet" | Select Macaddress

$ConvertMacHost= $MacHost[0] -replace '(:|-|\.)'
Write-Host "You mac address is: " $MacHost
#MacHost gets reformatted to take out Semicolons - Ex 0011223344AA


#MacLab is a variable that stores the Computer name and Mac Address from File created in Deep Freeze that matches Mac Address of host.
#MacLab is formated to make all Alpha in Mac Address Capitalized 
$MacLab=Import-Csv 'C:/projectcsv/LH_office.csv' | Select Workstations,@{Label ="Mac Address"; Expression ={$_."Mac Address".ToUpper()}}|where-object {$_."Mac Address" -eq $ConvertMacHost}|Select Workstations

#Checks to see if Host Mac Address Matches CSV File
If ([string]::IsNullorEmpty($MacLab))
{

    Write-Warning  -Message "No Mac Address found in our Records that Match the Host Machine Mac Address: Exit code 11001"  
    write-host "" 
    exit 11001
   
    }Else{
        
$strUser = "******\domainadd"
$strDomain = "******"
$strPassword = ConvertTo-SecureString "*******" -AsPlainText -Force
$Credentials = New-Object System.Management.Automation.PsCredential $strUser,
$strPassword

#---- Define Prefix to be used -----#
$strPrefix='LH'
$strEnding='DESK'

#----- Get Serial Number ------#

$SN=(gwmi win32_BIOS).serialnumber

#--If working with VM, the SN length is longer than 15 Char------#
if($SN.length -gt 11) {
    #Get the last 7 Char of Serial
    $StrName=($SN.substring($SN.length - 11)) -replace "-",""
           
            $strComputerName=$strPrefix+"-"+$StrName+"-"+$strEnding
    } else {$strComputerName=$strPrefix+"-"+$SN+"-"+$strEnding

    }

    #------ Rename the Computer using WMI --------#
    #$computer=gwmi win32_computersystem
    #$computer.rename($strComputerName)

    #-----Powershell 5 above use-------#

    rename-computer -NewName $StrComputerName -PassThru -DomainCredential $Credentials

运行代码时，我收到以下错误消息：

我将正在工作的计算机添加到csv中，但仍然收到错误。我知道以后我必须添加一个函数，它会检查名称是否已经在AD中。但我想先让它工作。请告诉我你能提供的任何帮助都会有帮助的

编辑：这是一张CSV文件的图片，显示了其中包含的信息。

在进行了修改之后，我在脚本运行时得到了这些错误

$MacHost

正在接收具有属性的对象，因此您需要指定所需的属性，否则会得到奇怪的结果，这将导致

Where object

失败

具体来说，

$ConvertMacHost

最终类似于

@{MacAddress=9CB6D0959AE5}

这条线

$ConvertMacHost=$MacHost[0]-替换“（：|-|\”

应该是

---

$ConvertMacHost=$MacHost[0]。MacAddress-replace'（：|-| \.）

尝试这样设置$ConvertMacHost

$ConvertMacHost=$MacHost[0]。MacAddress-replace'（：|-| \.）

更好吗？检查if语句之前的

MacLab

的值，查看它是否确实为null或空。。。

MacLab

中的select子句似乎很长，看看没有它会发生什么。CSV的内容是什么？添加了CSV文件的图片。不知道如何上传以便下载。这些错误看起来与您发布的代码无关。。。显示错误的带下划线部分与代码中的任何内容都不对应。当脚本运行时MDT给出的输出日志出现错误时。所以我不确定是否正确。在对脚本进行更正后，当脚本运行时，我会得到这些错误。有人有什么想法吗。
