在Global.asax启动一条线程就ok了，下面是启动线程定时写文件的例子
Global.asax
C# code
Code
1<%@ Application Language="C#" %>
2<%@ Import Namespace="System.IO" %>
3<%@ Import Namespace="System.Threading" %>
4<script runat="server">
5 string LogPath;
6 Thread thread;
7 void WriteLog()
8 {
9 while (true)
10 {
11 StreamWriter sw = new StreamWriter(LogPath, true, Encoding.UTF8);
12 sw.WriteLine(thread.Name + ":" + DateTime.Now.ToString());
13 sw.Close();
14 Thread.CurrentThread.Join(1000 * 60);//阻止1分钟
15 }
16 }
17 void Application_Start(object sender, EventArgs e)
18 {
19 LogPath = HttpContext.Current.Server.MapPath("log.txt");
20 //在应用程序启动时运行的代码
21 thread = new Thread(new ThreadStart(WriteLog));
22 thread.Name = "写登录日志线程";
23 thread.Start();
24 }
25
26 void Application_End(object sender, EventArgs e)
27 {
28 //在应用程序关闭时运行的代码
29
30 }
31
32 void Application_Error(object sender, EventArgs e)
1.连接数据库文件
<add name="LocalSqlServer" connectionString="Data Source=.\SQLExpress;Integrated Security=True;AttachDBFilename=|DataDirectory|TimeTracker.mdf;User Instance=true" />
SqlConnectionStringBuilder实例化时，要用到connectionString，如：SqlConnectionStringBuild builder = new SqlC ......
