PowerShell multiple email recipients (attachment) from csv / empty cell issue - powershell

Question

I recently started to work on PS script for email automation.
Manage to put something together where I have CSV file from where PowerShell is extracting data (multiple recipients, attachment, etc).
The problem is, when some of the cells are empty, script won`t work.
There is one similar question, but I am just not sure how to implement solution on my case:
$importFile = "Users.csv"
$users = import-csv $importFile | select *
foreach($user in $users)
{
$Name = $user.'Name'
$to = $user.'To'
$to2 = $user.'To2'
$Attachment = $user.'Attachment'
$Attachment2 = $user.'Attachment2'
$write = "Emailing account " + $to + " ..."
Write-Host $write
$body = [string]::join([environment]::newline, (Get-Content -path $emailFile))
$body = $body.Replace('[Name]', $Name)
$mail = New-Object System.Net.Mail.MailMessage
$mail.From = $emailFrom
$mail.To.Add($to)
$mail.To.Add($to2)
$mail.Subject = $emailSubject
$mail.IsBodyHtml = $true
$mail.Body = $body
$mail.Attachments.Add($Attachment)
$mail.Attachments.Add($Attachment2)
$smtp = New-Object System.Net.Mail.SmtpClient
$smtp.Host = $smtpServerHost
$smtp.Port = $smtpServerPort
$smtp.EnableSsl = $smtpServerSsl
$smtp.UseDefaultCredentials = $false
$smtp.Credentials = $credentials
$smtp.Send($mail)
This is how looks CSV file
Any suggestion is more than welcome :)

Answer 1

Try Where-Object to filter out rows.
$users = Import-Csv $importFile |
Where-Object {$_.Name -ne ""} |
Select-Object *
For what it is worth: if the whole "row" is blank you can shortcut this to simply be
...
Where-Object {$_} |
...

Implementing IF function resolved the case. For example if ($to2 -ne '') is checking if $to2 cell is empty. If no, then $mail.To.Add($to2). The same situation for $Attachment. Here is the code:
$mail = New-Object System.Net.Mail.MailMessage
$mail.From = $emailFrom
$mail.To.Add($to)
if ($to2 -ne '') {
$mail.To.Add($to2)
}
$mail.Subject = $emailSubject
$mail.IsBodyHtml = $true
$mail.Body = $body
$mail.Attachments.Add($Attachment)
if ($Attachment2 -ne '') {
$mail.Attachments.Add($Attachment2)
}
