Sending an HTML Email with Visual Studio 2005

  • Artikkeli

Question: I am trying to send an email with Visual Studio 2005 using System.Web.Mail and it keeps telling me that it is obsolete? What should I use? Also if you have an example of how to send an HTML email that would also help.

Answer: Within Visual Studio 2005 you can use the System.Net.Mail namespace. This contains the classes used to send email using SMTP. The MailMessage class is used to represent the content of an email message. The SmtpClient transmits email to the SMTP host that you designate for mail delivery. For example you can use the following code within a button of a Windows form to send an HTML email.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim client As New SmtpClient("smtp.server")
        Dim toAddr As New MailAddress(trobbins@microsoft.com)  
        Dim fromAddr As New MailAddress(trobbins@microsoft.com)
        Dim message As New MailMessage(fromAddr, toAddr)

        message.IsBodyHtml = True
        message.Subject = "This is a Test"

        message.Body = "<html><body><b>This is an </b> <font color=red>HTML Message</font></body></html> "

        client.Send(message)

    End Sub

The email that is sent looks like the following

    Have you thought about MIME encodings ?

    For Mime encodings .NET 2.0 has a new namespace of system.net.mime that should help with that.

    Hey, nice example, I tried it and I'm using my pc as the mail server ie using 127.0.0.1 to replace your "smtp.server".

    I'm having a problem though because all the mail seems to be staying in the Queue folder (btw, i'm using w2k3), any ideas? (I'm tryin to send the message To an external address, let's say j@wdser.com)

    THanks in advance!

    You need to make sure that you have both SMTP and a relay set up to get the email out. I think there are some articles on MSDN/Technet that talk about the actual set up.

    I believe I have and I've checked the log and I see comments such as:

    #Fields: time c-ip cs-method cs-uri-stem sc-status
    23:04:04 127.0.0.1 EHLO - 250
    23:04:04 127.0.0.1 MAIL - 250
    23:04:04 127.0.0.1 RCPT - 250
    23:04:04 127.0.0.1 DATA - 250
    23:05:43 127.0.0.1 QUIT - 240

    Which I believe should mean that there were no problems in sending...?
