Powershell foreach创建了多个csv文件，我希望在创建后通过电子邮件发送这些文件。如何才能做到这一点？

$files = @("file1.csv", "file2.csv", "file3.csv")

foreach ($file in $files) {
    # 生成csv文件的代码
    # ...
    $data | Export-Csv -Path $file -NoTypeInformation
}

$smtpServer = "smtp.example.com"
$smtpPort = 587
$smtpUsername = "your_username"
$smtpPassword = "your_password"

$from = "sender@example.com"
$to = "recipient@example.com"
$subject = "CSV Files"
$body = "Please find the attached CSV files."

foreach ($file in $files) {
    # 发送邮件的代码
    # ...
    $attachment = $file
    Send-MailMessage -SmtpServer $smtpServer -Port $smtpPort -UseSsl -Credential (New-Object System.Management.Automation.PSCredential($smtpUsername, (ConvertTo-SecureString -String $smtpPassword -AsPlainText -Force))) -From $from -To $to -Subject $subject -Body $body -Attachments $attachment
}
