To summarize the ASP.NET’s SmtpEmail functionality, an e-mail form containing all the fields and configurable properties is shown in Listing 15.5. In Figure 15.2, you can see the application running. It allows users to enter the information with which the e-mail will be sent.
Figure 15.2. Sending an e-mail using the MailMessage object.
We’ll start with the Visual Basic version.

Sub SendMyEMail (Obj As Object, E As EventArgs)
Dim mailObj AS new MailMessage
mailObj.From = Request.Form(“FromAddress”)
mailObj.To = Request.Form(“ToAddress”)
mailObj.CC = Request.Form(“CCAddress”)
mailObj.BCC = Request.Form(“BCCAddress”)
mailObj.Subject = Request.Form(“Subject”)
If(Len(Request.Form(“Attachments”)) > 0) Then
mailObj.Attachments.Add(new MailAttachment(Request.Form(“Attachments”)))
End If
select case Request.Form(“Format”)
case “Text”
mailObj.BodyFormat = MailFormat.Text
case “HTML”
mailObj.BodyFormat = MailFormat.HTML
