可以在Global.asax 中定义,直接上例子:
<script runat="server">
void Application_Start(object sender, EventArgs e)
{
YN~MB
DdY.w `#D0
// 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";

上面 是一个定时发邮件的小例子,一举两得,还给大家了一个发邮件的例子 ,呵呵
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~
