问题描述

有人知道为什么会这样吗？

anybody knows why is this happening ?

推荐答案

Application_Start 在加载应用程序域时触发事件一次。如果你看到它不止一次触发，那么这意味着应用程序重新启动。应用程序域可以卸载有多种原因，例如删除修改某些文件，如 web.config ， bin 文件夹，...这是描述应用程序重启的常见原因的文章。

The Application_Start event is fired once when the application domain is loaded. If you see it firing more than once then this would mean that the application restarts. There are multiple reasons an application domain could get unloaded like deleting modifying some of the files like web.config, the bin folder, ... Here's an article describing common reasons for application restart.
