sending email with attachment file in .net

First Step, we have ASP.NET applications you configure this in your application’s web.config file.

Config code

  <system.net>

    <mailSettings>

      <smtp from="anil.singh@gmail.com" deliveryMethod="Network">

        <network host="smtp.gmail.com" port="587" userName=anil.singh@gmail.com password="password#123" defaultCredentials="false"/>

      </smtp>

    </mailSettings>

  </system.net>

Second Step, c# code

using System.Net.Mail;

protected void btnMailSend_Click(object sender, EventArgs e)

        {

            try

            {

                string contributionFile = string.Empty;

                if (flAttachment.HasFile && Path.GetExtension(flAttachment.FileName) == ".xls")

                {

                    flAttachment.SaveAs(Server.MapPath("~/FolderPath/") + flAttachment.FileName);

contributionFile = Server.MapPath("~/FolderPath/") + flAttachment.FileName;

                }

                MailMessage mm = new MailMessage();

                mm.From = new MailAddress("anil.singh@gmail.com");

                mm.To.Add(txtMailTo.Text);

                mm.Subject = "This is your File" + monthName;

                mm.Body = txtMailMessage.Text;

                mm.IsBodyHtml = true;

                mm.Priority = MailPriority.High;

                Attachment attach = new Attachment(contributionFile);

                mm.Attachments.Add(attach);

                SmtpClient client = new SmtpClient("smtp.gmail.com", 587);

                client.EnableSsl = true;

                client.Credentials = new NetworkCredential("anil.singh@gmail.com", "password#123");

                client.Send(mm);

                client.Timeout = 120;

            }

            catch (Exception ex)

            {

            }

        }

If you want to send this mail to Different person at a time, then we write to this..

using System.Net.Mail;

protected void btnMailSend_Click(object sender, EventArgs e)

        {

            try

            {

                string contributionFile = string.Empty;

                if (flAttachment.HasFile && Path.GetExtension(flAttachment.FileName) == ".xls")

                {

                    flAttachment.SaveAs(Server.MapPath("~/FolderPath/") + flAttachment.FileName);

contributionFile = Server.MapPath("~/FolderPath/") + flAttachment.FileName;

                }

                MailMessage mm = new MailMessage();

                mm.From = new MailAddress("anil.singh@gmail.com");

  mm.To.Add(new MailAddress("hrTeam@gmail.com"));

  mm.To.Add(new MailAddress("adminTeam@gmail.com"));

  mm.To.Add(new MailAddress("Manager@gmail.com")); 

  mm.CC.Add(new MailAddress("Boss@gmail.com"));

                mm.Subject = "This is your File" + monthName;

                mm.Body = txtMailMessage.Text;

                mm.IsBodyHtml = true;

                mm.Priority = MailPriority.High;

                Attachment attach = new Attachment(contributionFile);

                mm.Attachments.Add(attach);

                SmtpClient client = new SmtpClient("smtp.gmail.com", 587);

                client.EnableSsl = true;

                client.Credentials = new NetworkCredential("anil.singh@gmail.com", "password#123");

                client.Send(mm);

                client.Timeout = 120;

            }

            catch (Exception ex)

            {

            }

        }
