c# - Show Progress bar with smtpClient.send

Question

I am using this function to send mails via gmail.

private bool uploadToGmail(string username, string password , string file , 
    string backupnumber)
{
    MailMessage mail = new MailMessage();
    SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
    mail.From = new MailAddress("jain@gmail.com");
    mail.To.Add("jain@gmail.com");
    mail.Subject = "Backup mail- Dated- " + DateTime.Now + " part - " + 
        backupnumber;
    mail.Body = "Hi self. This mail contains 
 backup number- " + 
        backupnumber + " 
 Dated- " + DateTime.Now ;

    System.Net.Mail.Attachment attachment;
    attachment = new System.Net.Mail.Attachment(file);
    mail.Attachments.Add(attachment);

    SmtpServer.Port = 587;
    SmtpServer.Credentials = 
        new System.Net.NetworkCredential("jain@gmail.com", "password");
    SmtpServer.EnableSsl = true;

    SmtpServer.Timeout = 999999999;
    SmtpServer.Send(mail);
    //  MessageBox.Show("mail Sent");
    return true;
}

Now I want to show a progress bar (in case there is a large attachment) to show the upload . Is this possible ? I think I know how to use a progress bar, but don't know how to use it with Smtpclient.send() .

any help ?

Thanks

You should use SendAsync and subscribe to SendCompleted, to know, when the sending your mail completed. There is no way to get the progress of the send process, though...
