如何在截止日期前7天向会员发送自动邮件？ [英] How to send automatic mail to members before 7 days from due date?

问题描述

您好，



我有一个申请，所有会员都应该在截止日期前一周收到电子邮件。

例如。如果截止日期是6月30日，那么会员应该在6月23日收到电子邮件以支付会费。



对于发送邮件，我使用了以下代码：

Hello,

I have an application where all the members should receive an email 1 week before the due date.
for eg. If the due date is 30th June then the members should receive email on 23rd June for paying their dues.

For sending mail I have used following code:

MailMessage Msg = new MailMessage();
                Msg.From = new MailAddress("[e-mail]");
                Msg.To.Add("[e-mail]");
                Msg.Subject = "Message from  Website";
                string body = "Your maintenance for month June is INR 500 and should be paid by 30th June. If paid after this date your amount will be 600. Please ignore if already paid. ";
               
             
                Msg.Body = body;

                // your remote SMTP server IP.
                SmtpClient smtp = new SmtpClient();
                smtp.Host = "localhost";
                smtp.Port = 25;
                smtp.Send(Msg);
                Msg = null;

请帮我解决这个。

提前致谢。

推荐答案

public void SendMail()
       {
           DateTime dueDate = Convert.ToDateTime("06/30/2014");
           DateTime currentDate = DateTime.Now;
           System.TimeSpan diffDays = dueDate.Subtract(currentDate);
           if (diffDays.Days == 7)
           {

               //Write the logic to send mail;
           }

       }

如上所述构建一个Windows服务并安排它每天运行一次。

Build a windows service as above and schedule it run once a day.
