powershell - Powershell Get-ChildItem

Question

我写了一个Powershell脚本来检查文件夹的内容，以及是否有LastWriteTime早于20分钟的文件通知我。我遇到的问题是，当我得到结果时，它包括电子邮件正文中的所有文件。我将如何编写该信息以仅获取电子邮件正文中的最新文件名？

$src = 'c:\test'
$sendmail = $false

Get-ChildItem -path $src | ForEach-Object { 
#write-host $_.fullname
$dtdiff = New-TimeSpan ($_.LastWriteTime) $(Get-Date)

if ($dtdiff.TotalMinutes -gt 20){
$strbody=$strbody +$_.fullname+ " Last File Modified at "  +$_.LastWriteTime +"`r`n"
$sendmail=$true
}       
}


#$strbody
 if($sendmail -eq $true){
# Email components
$strFromAddress = "abc@xyz.net"
$strToAddress = "abc@xyz.net"
$strMessageSubject = "REPORT"
$strMessageBody = $strbody
$strSendingServer = "smtp.com"
$SMTPPort = "587"
$emailSmtpUser = "abc@xyz.net"
$emailSmtpPass = "test123"
# Email objects
$objSMTPMessage = New-Object System.Net.Mail.MailMessage              $strFromAddress, $strToAddress, $strMessageSubject, $strMessageBody
$objSMTPClient = New-Object System.Net.Mail.SMTPClient(     $strSendingServer, $SMTPPort )
$objSMTPClient.EnableSsl = $true
$objSMTPClient.Credentials = New-Object System.Net.NetworkCredential( $emailSmtpUser , $emailSmtpPass );
$objSMTPClient.Send($objSMTPMessage)
}

仅获取最实际的文件:编辑以删除缺陷

Get-ChildItem -path $src | 
  Sort LastWriteTime | 
    Select -last 1 |
      ForEach-Object { 
        #write-host $_.fullname
        $dtdiff = New-TimeSpan ($_.LastWriteTime) $(Get-Date)
        if ($dtdiff.TotalMinutes -gt 20){
          $strbody=$strbody +$_.fullname+ " Last File Modified at "  +$_.LastWriteTime +"`r`n"
          $sendmail=$true
        }       
}
