1.在当前站点下添加Global.asax文件。

2.代码如下:

<%@ Application Language="C#" %>

<script runat="server">

void Application_Start(object sender, EventArgs e)
{

System.Timers.Timer timer = new System.Timers.Timer(1000);
timer.Elapsed += new System.Timers.ElapsedEventHandler(writelog);
timer.Start();
}

protected void writelog(object sender, System.Timers.ElapsedEventArgs e)
{
//check datetime, Do the job on 12:00 everyday.

if (DateTime.Now.Hour == 12 && DateTime.Now.Minute == 0)
{

string logdate = DateTime.Now.ToString("yy-MM-dd");
string logfilename = logdate + ".log";
string loglist = DateTime.Now.ToString();

if (System.IO.File.Exists(logfilename))
{
System.IO.StreamWriter swobj = System.IO.File.AppendText("C:\\" + logfilename);
swobj.WriteLine(loglist);
swobj.Flush();
swobj.Close();
}
else
{
System.IO.StreamWriter swobj = System.IO.File.CreateText("C:\\" + logfilename);
swobj.WriteLine(loglist);
swobj.Flush();
swobj.Close();
}
}
}

</script>
