在 PowerShell 中发送带有附件的电子邮件

Question

我想在这封电子邮件中发送一个CSV文件。我可以毫无问题地发送电子邮件，但是我尝试了很多方法来发送附件，但是最后发送电子邮件时没有附件。

function sendmail($Body) {
    $Smtp = New-Object System.Net.Mail.SmtpClient
    $MailMessage = New-Object System.Net.Mail.MailMessage
    $Smtp.Host = "smtp-server"
    $MailMessage.From = "[e-mail]"
    $MailMessage.To.Add("[e-mail]")
    $MailMessage.Subject = "Hello"
    $MailMessage.Body = $Body
    $smtp.Port = 25
    $smtp.EnableSsl = $false
    $Smtp.Send($MailMessage)
} 
$Body = "12334"
sendmail $Body

电子邮件只需如下所示：

您好，所有信息都在文件示例中.csv

Send-MailMessage有一种直接处理附件的方法。下面是示例。

Send-MailMessage -From "User01 <[e-mail]>" `
                       -To "User02 <[e-mail]>", `
                           "User03 <[e-mail]>" `
                       -Subject "Sending the Attachment" `
                       -Body "Forgot to send the attachment. Sending now." `
                       -Attachment "data.csv" -SmtpServer smtp.fabrikam.com

或者，你应该使用 System.Net.Mail.MailMessage ，然后你必须使用：

$EmailFrom = "<[e-mail]>"
$EmailTo = "<[e-mail]>"
$EmailSubject = "<email subject"  
$SMTPServer = "smtphost.domain.tld"
$SMTPAuthUsername = "username"
$SMTPAuthPassword = "password"
$emailattachment = "<full path to attachment file.csv>"
function send_email {
    $mailmessage = New-Object System.Net.Mail.MailMessage 
    $mailmessage.From = ($emailfrom) 
    $mailmessage.To.Add($emailto)
    $mailmessage.Subject = $emailsubject
    $mailmessage.Body = $emailbody
    $attachment = New-Object System.Net.Mail.Attachment($emailattachment, 'text/plain')
    $mailmessage.Attachments.Add($attachment)
    #$mailmessage.IsBodyHTML = $true
    $SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 25)  
    $SMTPClient.Credentials = New-Object System.Net.NetworkCredential("$SMTPAuthUsername", "$SMTPAuthPassword") 
    $SMTPClient.Send($mailmessage)
}
