想在Web中定时 处理某些任务吧?
可以在Global.asax 中定义,直接上例子:
void Application_Start(object sender, EventArgs e) { // 应用程序启动时 System.Timers.Timer timer = new System.Timers.Timer(); DateTime sTime = DateTime.Now; int sHour = sTime.Hour; int sMin = sTime.Minute; int sSecond = sTime.Second; int sHourInterval = 15 - sHour; int sSecondInterval = sHourInterval * 60 * 60 * 1000; //timer.Interval = 1000*5;//5秒发送一次 timer.Interval = sSecondInterval; //timer.AutoReset; timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed); timer.Enabled = true; } void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { string s_from = "fengsheng@xxx.com"; string s_to = "fengsheng@xxx.com"; string pwd = "1234567"; string s_body = "test"; string s_smtp = "mail.xxx.com"; int i = s_from.IndexOf("@"); string s_subjetc = "test"; string username = s_from.Substring(0, i); System.Net.Mail.MailAddress from = new System.Net.Mail.MailAddress(s_from); System.Net.Mail.MailAddress to = new System.Net.Mail.MailAddress(s_to); System.Net.Mail.MailMessage mailobj = new System.Net.Mail.MailMessage(from, to); mailobj.Subject = s_subjetc; mailobj.Body = s_body; mailobj.IsBodyHtml = true; mailobj.BodyEncoding = System.Text.Encoding.GetEncoding("GB2312"); mailobj.Priority = System.Net.Mail.MailPriority.High; System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient(); smtp.Host = s_smtp; smtp.UseDefaultCredentials = true; smtp.Credentials = new System.Net.NetworkCredential(username, pwd); smtp.Send(mailobj); }
上面 是一个定时发邮件的小例子,建议最好是把需要启动的事项 做成 web Service 这样 应用范围会更广
