我正在尝试ping IP列表，但是我需要针对RAC和KVM测试它们的变体。我想获取IP地址（在 Data failed to compile:

变量中），并在对其执行ping操作之前将“ rac”附加到该地址。我还需要对“ arac”，“ raca”，“ kv”，“ akv”，“ kva”和“ kvm”执行ping操作，但是我只是在每次运行脚本后将其手动替换为脚本。 / p>
$ColumnHeader我尝试创建新变量Param(
[Parameter(Mandatory=$true, position=0)][string]$csvfile
)
$ColumnHeader = "Name"
#$string = "rac"
#$subServer = "$($ColumnHeader)$($string)"
Write-Host "Reading file" $csvfile
$ipaddresses = Import-Csv $csvfile | Select-Object $ColumnHeader
Write-Host "Started Pinging.."
foreach ($ip in $ipaddresses) {
if (Test-Connection $ip.($ColumnHeader) -Count 1 -Quiet) {
Write-Host $ip.("Name") "Ping succeeded." -Foreground Green
} else {
Write-Host $ip.("Name") "Ping failed." -Foreground Red
}
}
Write-Host "Pinging Completed."
和$string，并在第14行中使用它们代替$subServer，但是我得到“无法验证参数'ComputerName'的参数。 ”错误。
编辑：我将第7行从$ColumnHeader更改为$subServer = $ColumnHeader + $string，并且我可以在第14行上成功代替$subServer = "$($ColumnHeader)$($string)"呼叫$subServer，但是当我取消注释{{ 1}}在第6行，我再次收到上述“ ComputerName”错误。
