Sending Email with ASP.NET Part2: Attachment, HTML Format, Multiple Recipients

Sending Email with ASP.NET

Sending Email With Attachment

ASP.NET also provides a mechanism to attach files with our emails. To send an attachment with your email you need to use the following lines of code.

Dim Attach As MailAttachment = New MailAttachment("C:\images\sun.gif")
'creating an instance of MailAttachment class and specifying the location of attachment
mailMessage.Attachments.Add(Attach)
'adding the attachment to mailMessage

Sending Email to Multiple Recipients

To send an email to multiple recipients we need to specify the addresses of the recipients seperated by a semicolon as shown in the line of code below.

mailMessage.To = "xyz@abc.com;san@universe.com;sen@baw.com"

Sending an HTML Email

We all know that email messages can be either in plain text or HTML. By default they are sent as plain text, but we can change this to HTML by setting the BodyFormat property to Html. The following lines of code will show that.

mailMessage.Body = "<html><body>" & "This tutorial is sending an HTML email_
with an ASP.NET app." & "</body></html>"

The text sent with the above lines of code will be bold and underlined. You can use HTML tags to send an HTML email as shown above.
