Cannot find an overload for "Add" and the argument count: "1"

Question

I got two different scripts and combined them to check a specific folder for new file and email that file as attachment.

Here's the code combined:

Param (
    $Path = "C:\path"
    )

$File = Get-ChildItem $Path | Where { $_.LastWriteTime -ge [datetime]::Now.AddMinutes(-10) }
If ($File)
{   
$emailSmtpServer = "smtp.xxxx.com"
$emailSmtpServerPort = "587"
$emailSmtpUser = "[email protected]"
$emailSmtpPass = "xxxxxxxx"

$emailMessage = New-Object System.Net.Mail.MailMessage
$emailMessage.From = "Xxxx Xxxx <[email protected]>"
$emailMessage.To.Add( "[email protected]" )
$emailMessage.Subject = "File Test Report"
$emailMessage.IsBodyHtml = $false
$emailMessage.Body = "Weekly Report"

$SMTPClient = New-Object System.Net.Mail.SmtpClient( $emailSmtpServer , $emailSmtpServerPort )
$SMTPClient.EnableSsl = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential( $emailSmtpUser , $emailSmtpPass );
$attachment = $File
$emailMessage.Attachments.Add($attachment)

$SMTPClient.Send($emailMessage) 
}

The code works fine, it looks for new file and sends the email except it won't attach the file and I get the following error

Cannot find an overload for "Add" and the argument count: "1".
At D:\SendEmail2.ps1:24 char:1
+ $emailMessage.Attachments.Add($attachment)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodException
    + FullyQualifiedErrorId : MethodCountCouldNotFindBest

I think it has something to do with calling the file with $attachment = $File

Can anyone help?

Solution

You probably have to create a Attachment object first and also have to deal with multiple files so replace the following lines:

$attachment = $File
$emailMessage.Attachments.Add($attachment)

with:

$File | ForEach-Object {
    $filePath = $_.FullName
    $attachment = new-object Net.Mail.Attachment($filePath)
    $emailMessage.Attachments.Add($attachment)
}
