Global.asax.cs中的Session_Start和Session_End

Question

這兩個事件處理程序屬於哪個類的事件？

例如， Global.asax中的 Application_BeginRequest通過命名約定被注冊到HttpApplication類的BeginRequest。

在這3個類中，關於這2個會話事件，我找不到任何東西： HttpApplication ， HttpContext ， HttpSessionState

Answer 1

它們屬於SessionStateModule 。

它是舊的文檔，但是如果您從將模塊與Global.asax文件一起使用開始，您會看到可以訂閱的事件由實現IHttpModule接口的類型公開。 並查看該接口的文檔，您將找到實現IHttpModule的內置類型：
