PowerShell function result wont be send via Email - email

Question

I'm using this PowerShell function to check on a folder.
it works fine and when adding, changing and deleting a file happens on the folder; it shows the log message on the host screen.
$FileSystemWatcher = New-Object System.IO.FileSystemWatcher
$FileSystemWatcher | Get-Member -Type Properties,Event
$FileSystemWatcher.Path = "C:\Users\ali.shariaty\Desktop\test"
Register-ObjectEvent -InputObject $FileSystemWatcher -EventName Created -Action {
$Object = "{0} was {1} at {2}" -f $Event.SourceEventArgs.FullPath,
$Event.SourceEventArgs.ChangeType,
$Event.TimeGenerated
$WriteHostParams = #{
ForegroundColor = 'Green'
BackgroundColor = 'Black'
Object = $Object
}
Write-Host #WriteHostParams
}
Register-ObjectEvent -InputObject $FileSystemWatcher -EventName Changed -Action {
$Object = "{0} was {1} at {2}" -f $Event.SourceEventArgs.FullPath,
$Event.SourceEventArgs.ChangeType,
$Event.TimeGenerated
$WriteHostParams = #{
ForegroundColor = 'Yellow'
BackgroundColor = 'Black'
Object = $Object
}
Write-Host #WriteHostParams
}
Register-ObjectEvent -InputObject $FileSystemWatcher -EventName Deleted -Action {
$Object = "{0} was {1} at {2}" -f $Event.SourceEventArgs.FullPath,
$Event.SourceEventArgs.ChangeType,
$Event.TimeGenerated
$WriteHostParams = #{
ForegroundColor = 'Red'
BackgroundColor = 'Black'
Object = $Object
}
Write-Host #WriteHostParams
}
My issue is when I add these lines to my code to send me the result by email, the body of my emails are empty and do not contain the log message.
$mailtxt = $WriteHostParams
$mailSmtpServer = "mail.domain.com";
$mailFrom = "ali.shariaty#domain.com";
$mailTo = "ali.shariaty#domain.com";
$mailSubject = "Folder Change"
$mailbody = $mailtxt
$mail = New-Object Net.Mail.SmtpClient($mailSmtpServer);
$msg = new-object Net.Mail.MailMessage;
$msg.IsBodyHtml = 1;
$msg.To.Add($mailTo);
$msg.From = $mailFrom;
$msg.Subject = $mailSubject;
$msg.Body = $mailbody;
$mail.Send($msg);
Can someone help and tell me what I am doing wrong?
Thank you.

Answer 1

Have you tried setting the body to just the message? i.e.
$mailtext = $WriteHostParams.Object
Currently you are trying to set the body of the email to a hashtable, which I would expect would just set it to "System.Collections.Hashtable" after it was casted to a string
