Hi,
I am really struggling with an issue and will be grateful if you expert can provide some good solution.
My problem is that i need to write a window service that could look for some detail in database and send mail...I have written a service but i want it to run every hour.
How can i achieve this??Below is the code.
using System;
using System.Collections.Generic;
using System.ComponentModel;

e.SendEmailTOAllUser();
}
private static void SendCompletedCallback(object sender, AsyncCompletedEventArgs e)
{
// Get the unique identifier for this asynchronous operation.
String token = (string)e.UserState;
String timestamp;
if (e.Error != null)
{
throw new Exception(e.ToString());
}
else
{
timestamp = DateTime.Now.ToString();
}
mailSent = true;
}

MailMessage msg = new MailMessage();
try
{
MailMessage msg = new MailMessage();
msg.From = new MailAddress("pssp@gmail.com", "OUR SYSTEM");
// In case the mail system doesn't like no to recipients. This could be removed
msg.To.Add("pssp@gmail.com");
msg.Bcc.Add(toAddresses);
msg.Subject = MailSubject;
msg.Body = MessageBody;
msg.IsBodyHtml = isBodyHtml;
//Response.Write(msg);

推荐答案
而不是写作这是一个Windows服务，将其作为独立应用程序编写，并使用内置的任务计划程序安排它每小时运行一次：
http://windows.microsoft.com/en-gb/windows/schedule-task [ ^ ]
Rather that writing this as a Windows Service, write it as a standalone application and use the built-in Task Scheduler to schedule it to run every hour:
http://windows.microsoft.com/en-gb/windows/schedule-task[^]
只需安排任务窗口。点击此处：

祝你好运！
Simply schedule task a windows. Check here:
