Question

我正在创建一个Windows服务，以特定的时间间隔发送邮件。我想启用一个计时器来处理mail_send()。

private void timer1(object sender, EventArgs e) {
    // I need a code here to work with email_send()
    timer1.Elapsed += new ElapsedEventHandler(email_send);
}

public void email_send(object sender, System.Timers.ElapsedEventArgs e) {
    MailMessage mail = new MailMessage();
    SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
    mail.From = new MailAddress("email from");
    mail.To.Add("emailto");
    mail.Subject = DateTime.Now +"logfile";
    mail.Body = "mail with log file attachment";

    System.Net.Mail.Attachment attachment;
    attachment = new System.Net.Mail.Attachment("F:\\logfile\\logfile.txt");
    mail.Attachments.Add(attachment);

    SmtpServer.Port = 587;
    SmtpServer.Credentials = new System.Net.NetworkCredential("emailfrom", "password");
    SmtpServer.EnableSsl = true;

    SmtpServer.Send(mail);
}

Answer 1

你应该通过调用方法Start（）来运行你的计时器，以“启用”它。

private void timer1(object sender, EventArgs e)
{
    timer1.Elapsed += new ElapsedEventHandler(email_send);
    timer1.Start();
}

首先初始化计时器

public static void Main()
{
InitializeTimer();
timerr.Start();
}

您可以使用开始和停止来启动timmer和Stop timmer

private void InitializeTimer()
 {
  Timer timerr = new Timer();
  timerr.Interval = 5000;
  timerr.Tick += Timerr_Tick;
  }

然后写下tick事件。

private void Timerr_Tick(object sender, EventArgs e)
    {
         MailMessage mail = new MailMessage();
         SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
          mail.From = new MailAddress("email from");
         mail.To.Add("emailto");
         mail.Subject = DateTime.Now +"logfile";
         mail.Body = "mail with log file attachment";

         System.Net.Mail.Attachment attachment;
         attachment = new System.Net.Mail.Attachment("F:\\logfile\\logfile.txt");
         mail.Attachments.Add(attachment);

         SmtpServer.Port = 587;
         SmtpServer.Credentials = new System.Net.NetworkCredential("emailfrom", "password");
         SmtpServer.EnableSsl = true;

SmtpServer.Send(mail);
}

在C＃中以一定间隔启用特定事件的计时器
