Powershell没有附件被发送

Question

我编写的脚本是否有问题，通过$ attachment验证文件目录是否正确，但似乎在发送电子邮件时，该文件未随电子邮件附上。< / p>

基本上if-else函数好像日志文件是今天的，它会发送电子邮件。是的，电子邮件正在成功发送，但没有附件。

$attachment = (get-childitem $dir\attachments | where {$_.name -match $lastlogfinalnumber}).fullname

if ($loglastwritedate -eq $today)
{ 
    $message = New-Object System.Net.Mail.MailMessage
    $message.subject = $subject
    $message.body = "$lastcompletetransfer"
    $message.to.add($to)
    $message.from = $username
    $message.attachments.add($attachment)



    $smtp = New-Object System.Net.Mail.SmtpClient($SMTPServer, $SMTPPort);
    $smtp.EnableSSL = $true
    $smtp.Credentials = New-Object System.Net.NetworkCredential($Username, $Password);
    $smtp.send($message)


}
