Global.asax.cs 中的 Session_Start 和 Session_End

Question

这两个事件处理程序属于哪个类的哪个事件？

例如的Application_BeginRequest在Global.asax中被命名约定注册的BeginRequest类的HttpApplication。

我在这 3 个类中找不到关于这 2 个会话事件的任何内容： HttpApplication、HttpContext、HttpSessionState

Answer 1

他们属于SessionStateModule.

这是旧文档，但如果您从使用具有 Global.asax 文件的模块开始，您将看到您可以订阅的事件由实现IHttpModule接口的类型公开。查看该接口的文档，您会发现实现的内置类型IHttpModule：
