PowerShell字典过滤掉ping失败

Question

我正在尝试过滤status=Offline打印机，并在电子邮件中将输出发送到$Body，您有什么想法可以做到这一点吗？到目前为止，输出显示了所有打印机和IT，而不考虑联机或脱机状态。

    Clear-Host
$printerip = @( 
"192.168.141.104","192.168.141.250","192.168.141.251","192.168.141.53","192.168.141.157","192.168.141.167",
"192.168.141.115","192.168.141.116","192.168.142.25","192.168.142.23","192.168.1 44.80","192.168.144.57","192.168.150.51",
"192.168.150.50","192.168.150.40"
)

$printername = @(
"Shoreline Color", 
"Dockside B/W", 
"Shoreline B/W",
"Spinnaker",
"BA Ricoh Printer",
"BA Xerox Color",
"BA Lab 1",
"BA Lab 2",
"Dowagiac Ricoh",
"Dowagiac Xerox Color",
"Paw Paw Ricoh",
"Paw Paw Xerox Color",
"330 Finance 1",
"330 Finance 2",
"330 Copierr"
)

$status = @()
foreach($printer in $printerip){
if(Test-Connection $printer -Count 2 -Quiet){
$status += "Online"
}else{
$status += "Offline"
}}

$count   = $printerip.Count
$counter = 0
$report  = @()
do{
$report +=$status[$counter]+" - "+$printerip[$counter]+" -     "+$printername[$counter] 
$counter++
}until($counter -ge $count)

if($report -match 'offline'){$body = ("We should probably do something about     this! `n `n") + $report | Out-String
Send-MailMessage -From "PrinterTest@domain.org" -To  "name@domain.org" -Subject "Printer Test" -Body $body  -SmtpServer   "mail.domain.org"}

在do...until循环中，您需要一条if语句来检查$status[$counter]是否等于' offline‘，以便只捕获脱机打印机，但是，我会尝试这样做，或者尝试将打印机信息放入它自己的单独csv文件中

$printers = @'
