添加一個全局應用程序類Global.asax
代碼會在訪問網站時運行
Global.asax代碼：
1 void Application_Start(object sender, EventArgs e)
2 {
3 // 在應用程序啟動時運行的代碼
4 System.Timers.Timer timer = new System.Timers.Timer(3600000);//設計時間間隔，如果一個小時執行一次就改為3600000
5 timer.Elapsed += new System.Timers.ElapsedEventHandler(Send);
6 timer.AutoReset = true;
7 timer.Enabled = true;
8 }
9
10 void Application_End(object sender, EventArgs e)
11 {
12 // 在應用程序關閉時運行的代碼
13 System.Threading.Thread.Sleep(5000);
14 string strUrl = "服務器地址";
15 System.Net.HttpWebRequest _HttpWebRequest = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(strUrl);
16 System.Net.HttpWebResponse _HttpWebResponse = (System.Net.HttpWebResponse)_HttpWebRequest.GetResponse();
17 System.IO.Stream _Stream = _HttpWebResponse.GetResponseStream();//得到回寫的字節流
18 _HttpWebResponse.Close();
19 }
20
21 void Application_Error(object sender, EventArgs e)
22 {
23 // 在出現未處理的錯誤時運行的代碼
24
25 }
26
27 void Session_Start(object sender, EventArgs e)
28 {
29 // 在新會話啟動時運行的代碼
30
31 }
32
33 void Session_End(object sender, EventArgs e)
34 {
35 // 在會話結束時運行的代碼。
36 // 注意: 只有在 Web.config 文件中的 sessionstate 模式設置為
37 // InProc 時，才會引發 Session_End 事件。如果會話模式設置為 StateServer
38 // 或 SQLServer，則不引發該事件。
