Sending a mail as both HTML and Plain Text in .net

Question

I'm sending mail from my C# Application, using the SmtpClient. Works great, but I have to decide if I want to send the mail as Plain Text or HTML. I wonder, is there a way to send both? I think that's called multipart.

I googled a bit, but most examples essentially did not use SmtpClient but composed the whole SMTP-Body themselves, which is a bit "scary", so I wonder if something is built in the .net Framework 3.0?

If not, is there any really well used/robust Third Party Library for sending e-Mails?

Answer 1

The MSDN Documentation seems to miss one thing though, I had to set the content type manually, but otherwise, it works like a charm :-)

MailMessage msg = new MailMessage(username, nu.email, subject, body); msg.BodyEncoding = Encoding.UTF8; msg.SubjectEncoding = Encoding.UTF8;  AlternateView htmlView = AlternateView.CreateAlternateViewFromString(htmlContent); htmlView.ContentType = new System.Net.Mime.ContentType("text/html"); msg.AlternateViews.Add(htmlView);
