使用 smtpClient.send 显示进度条

问题描述

我正在使用此功能通过 gmail 发送邮件.

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;
}

现在我想显示一个进度条(以防附件很大)来显示上传.这可能吗 ?我想我知道如何使用进度条，但不知道如何将它与 Smtpclient.send() 一起使用.

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() .

有什么帮助吗?

谢谢

推荐答案

你应该使用 SendAsync 并订阅 SendCompleted，知道何时发送您的邮件完成.但是，无法获取发送过程的进度...

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...
