我编写了一个用于重启网络上计算机的脚本。它运行良好，唯一的问题是主机中会弹出错误消息。该脚本会从一个txt文件（$Computers）中提取系统名称列表。我用一个我能访问的系统测试了该脚本，并在列表中添加了单词“wrench”，以模拟一个不在网络上的系统。测试脚本时，它在查找“wrench”时抛出了一条错误消息。以下是我目前脚本实际重启部分的内容：

#Actual restart portion (for privacy reasons, real file path replaced with "file-path")
#Starts by moving most recent log to archive folder
Get-ChildItem -Path "\\file-path\Computer Restarts\Logs" -Recurse -File | Move-Item -Destination "\\file-path\Computer Restarts\Logs\Archive" -Force

     #Determine script location, create new script, get current time and date
     $ScriptDir = Split-Path $script:MyInvocation.MyCommand.Path
     $Log = New-Item "\\file-path\Computer Restarts\Logs\$(Get-Date -f yyyy-MM-dd_hh-mm-ss) Restarts.txt" -ItemType File -Force
     $Date = Get-Date -Format "dd-MMM-yyyy hh:mm:ss"
     $Now = [datetime]::Now

     Clear-Host
     Write-Host `n `n `n
     Write-Host "Rebooting all computers and verifying reboot status..." `n `n
     Write-Host "Please standby, process may take up to 30 minutes..." `n `n

     Restart-Computer -ComputerName $Computers -Wait -For PowerShell -Delay 2 -Force -Timeout 1800 # Restarts all listed systems at once

     "----------------------------------Script executed on $Date----------------------------------" + "`r`n" | Out-File $Log -Append #First thing added to new log

     foreach($Computer in $Computers) #Checks each server to see if it has rebooted. Waits for confirmation before moving to next computer, skips computer if unresponsive after short time.
     {
         $LastBoot = (Get-CimInstance Win32_OperatingSystem -ComputerName $Computer -EA 0).LastBootUpTime
         $PingRequest = Test-Connection -ComputerName $Computer -Count 1 -Quiet

         if(($PingRequest -eq $true) -and ($LastBoot -gt $Now))
         {
             Add-Content -Path $Log -Value "$Computer`: Reboot Successful."
         }
         elseif ($PingRequest -eq $false)
         {
             Add-Content -Path $Log -Value "$Computer`: Computer not detected, please confirm."
         }
         else
         {
             Add-Content -Path $Log -Value "$Computer`: Restart not detected, please restart computer manually. Last detected boot up time is $LastBoot"
         }
     }

“Wrench”不会破坏脚本，据我所知，但我更希望脚本只是悄悄地处理它找不到的系统，只需将其附加到日志中，而不是在主机中抛出错误消息。

我正在尝试修改 PowerShell 脚本以在 CSV 文件中附加错误。一位前同事创建了一个脚本，用于从 txt 文件中获取计算机名称，浏览 Active Directory，并使用生成的分区和规范名称创建 CSV 文件（如果有帮助的话，创建 Excel 文件）。CSV 文件有三列；“Name”，直接保存txt文件中的名字；“部门”（取自 AD 中的“名称”），包含系统所属部门/部门的名称；和“CanonicalName”，它保存 AD 中显示的每个系统的完整规范名称。有时，计算机在 AD 中没有条目，它会向主机抛出一条错误消息，并且该系统将从 CSV 文件中丢失。下面是修改后的脚本，

这是我目前拥有的：

$ComputerList = Get-Content "File Path"
$Date = Get-Date -Format dd-MM-yyyy

foreach ($Computer in $ComputerList)
{
    if (@(Get-ADComputer $Computer -ErrorAction SilentlyContinue).Count) #Check if computer exists in AD
    {
       Get-ADComputer -Identity $Computer -Properties * | Select Name, @{n='Division'; e={([string]$_.o)}}, CanonicalName |
       Export-Csv "File Path" -NoTypeInformation -Append
    }
    else #Annotate if computer does not exist in AD
    {
       $NoComputer = [PSCustomObject]
       @{
          Name = $Computer
          Division = "Object Not Found"
          CanonicalName = " "
       }
       
       $CSVData = $NoComputer | ConvertTo-Csv -NoTypeInformation
       $CSVData | Select-Object -Skip 1 |
       Export-Csv "File Path" -NoTypeInformation -Append #<-- Error happens on this line, according to host
    }
}

当运行如上所示的脚本时，它仍然向主机抛出错误消息，以及每个缺失系统的两列，如下所示（出于隐私原因未显示实际计算机名称）：

Name                           Value                                                                                                                                                          
----                           -----                                                                                                                                                          
Name                           ComputerName                                                                                                                  
CanonicalName                                                                                                                                            
Division                       Object Not Found

它还会在主机中抛出以下错误消息：

Export-Csv : Cannot append CSV content to the following file: File Path\Computer 
Identity List.csv. The appended object does not have a property that corresponds to the following column: Name. To continue with mismatched properties, add the -Force parameter, and then 
retry the command.
At File Path.ps1:36 char:8
+        Export-Csv File Path
+        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidData: (Name:String) [Export-Csv], InvalidOperationException
    + FullyQualifiedErrorId : CannotAppendCsvWithMismatchedPropertyNames,Microsoft.PowerShell.Commands.ExportCsvCommand

然后，当我希望它列出系统并附加它在 CSV 文件的“分区”列中找不到带有“未找到对象”的系统时，它会在 CSV 文件中忽略该系统。我尝试执行 -Force，但它只是创建一个空白行。根据我查到的内容，这应该有效，但显然我错过了一些东西。为了使这项工作正常进行，我需要改变什么？
