ASP.Net Sending E-mail Attachment

Sending E-mail Attachment

Let us now look at how to include attachments to our e-mail. Open the web-page in design mode and add an HTML file upload control to the form. Set it to run at Server, and switch to code-behind to make changes in our previous method.

Dim msg As New Net.Mail.MailMessage(
_txtFrom.Text,
_txtTo.Text,
_txtSubject.Text,
_txtMessage.Text)
If fileUpload.PostedFile.FileName = "" Then
Else
msg.Attachments.Add( _
New System.Net.Mail.Attachment _
(fileUpload.PostedFile.FileName))
End If

All you need to do is check if the user posted a file or not, and if he did, then you need to create a new Net.Mail.Attachment object and add that to the MailMessage Object's Attachments collection. The line of code doing that could be broken down into the following, for simplicity;

Dim strName As String = fileUpload.PostedFile.FileName
Dim myAttachment As System.Net.Mail.Attachment
myAttachment = New Net.Mail.Attachment(strName)
msg.Attachments.Add(myAttachment)

ASP.Net - Send simple e-mail

Send simple e-mail

The code to send a simple e-mail is pretty simple and very small. There isn't much to explain either.

Dim msg As New Net.Mail.MailMessage(
_txtFrom.Text, _txtTo.Text,
_txtSubject.Text, _txtMessage.Text)

Dim mySmtp As New Net.Mail.SmtpClient("localhost")
Try
mySmtp.Send(msg)
lblResult.Text = "Mail Sent"
Catch ex As Exception
lblResult.Text = ex.Message
End Try
