Hi Jessy,

If you want to know how to send the email with the attenchment file?

If this is your requirement,I suggest you could use FileUpload control to get file and use SmtpClient class and MailMessage's Attachment class to realize sending e-mail requirement.

Notice: Different mailboxes have different port numbers, such as google mailbox with a port number of 587.

More details, you could refer to below codes:

aspx:

        <asp:FileUpload ID="FileUpload1" runat="server" /><br />
         <asp:Button ID="Button2" runat="server" Text="send" OnClick="Button2_Click" />

Code-behind:

 
protected void Button2_Click(object sender, EventArgs e)
        {
            SmtpClient smtpClient = new SmtpClient("smtp.gmail.com", 587);
            smtpClient.Credentials = new System.Net.NetworkCredential("[e-mail]", "");
            smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
            smtpClient.EnableSsl = true;
            MailMessage mail = new MailMessage();
            mail.From = new MailAddress("[e-mail]");
            mail.To.Add(new MailAddress("[e-mail]"));
            string fname = FileUpload1.PostedFile.FileName;
            mail.Attachments.Add(new Attachment(FileUpload1.PostedFile.InputStream, fname));
            try
            { 
                smtpClient.Send(mail);
                Response.Write("send email successfully");
            }
            catch (Exception error)
            {
                Response.Write("fail in send" + error.Message);
            }
        }
    }

Best Regards,

Hi Jessy,

Of course.

VB.NET Codes:

    Protected Sub Button2_Click(ByVal sender As Object, ByVal e As EventArgs)
        Dim smtpClient As SmtpClient = New SmtpClient("smtp.gmail.com", 587)
        smtpClient.Credentials = New System.Net.NetworkCredential("[e-mail]", " ")
        smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network
        smtpClient.EnableSsl = True
        Dim mail As MailMessage = New MailMessage()
        mail.From = New MailAddress("[e-mail]")
        mail.[To].Add(New MailAddress("[e-mail]"))
        Dim fname As String = FileUpload1.PostedFile.FileName
        mail.Attachments.Add(New Attachment(FileUpload1.PostedFile.InputStream, fname))

        Try
            smtpClient.Send(mail)
            Response.Write("send email successfully")
        Catch [error] As Exception
            Response.Write("fail in send" & [error].Message)
        End Try
    End Sub
