How to send mail with attachment in asp.net

Hi..

In this article i am going to explain to send mail by using multiple attachment in ASP.NET.

Now In this article you can send a mail with attachment.Its very easy process, add fileupload control from the toolbox
and design a page like below ,then add the following code..

First you have to import the namespace....

system.net.mail

Then write the below code in Send Button Click Event.......

 Dim mail As System.Net.Mail.MailMessage = New System.Net.Mail.MailMessage()

        Dim attach1 As String

        mail.To.Add(TextBox2.Text)

'checking CC and BCC textbox empty or Not

        If Not TextBox3.Text = "" Then

            mail.CC.Add(TextBox3.Text)

        End If

        If Not TextBox4.Text = "" Then

            mail.Bcc.Add(TextBox4.Text)

        End If

 mail.Subject = TextBox5.Text

        mail.From = New MailAddress(TextBox1.Text)

        mail.Body = TextBox6.Text

If attachment.HasFile Then

            mail.Attachments.Add(New Attachment(attachment.PostedFile.InputStream, attachment.FileName))

        End If

        If attachment2.HasFile Then

            mail.Attachments.Add(New Attachment(attachment2.PostedFile.InputStream, attachment2.FileName))

        End If

        mail.IsBodyHtml = True

        Dim smtp As SmtpClient = New SmtpClient()

        smtp.Host = "smtp.gmail.com"

               smtp.Credentials = New System.Net.NetworkCredential("Gmailusername", "password")

        smtp.EnableSsl = True

        Label1.Text = "Your mail has sent"

        Try

            smtp.Send(mail)

        Catch ex As Exception

            Label1.Text = "The email cannot be sent" + ex.ToString()

        End Try

For Sending mail through yahoo you have to change following thing in the above code...

smtp.Host = "smtp.mail.yahoo.com"

smpt.port=25

smtp.EnableSsl = False

smtp.Credentials = New System.Net.NetworkCredential("Yahoousername", "password")

i hope this helpful to you..........
