ASP.NET - 执行某些代码的全局位置？
我有一个 .net 新手问题。
在每个页面加载之前编写一些全局执行的代码的好地方在哪里？我要做的一些操作是：
a）打开数据库连接 b) 检查会话以查看用户是否登录 c）也许初始化一些对象
我正在考虑在主文件中执行此操作，但不确定这是否是一个好主意。也许对于列出的每个操作，.Net 中可能已经有一个功能可以做到这一点，这样我就不必“重新发明”轮子。
I have a newbie .net question.
Where would be a good place to write some code that executes globally before each page load? Some operations that I would be doing are:
a) open a database connection
b) check the session to see if user is logged in
c) maybe initialize a few objects
I was thinking of doing this in a master file, but wasn't sure if that's a good idea. And maybe for each of the operations listed, maybe there's a feature in .Net that does it already, so that I don't have to "re-invent" the wheel.

我将创建一个所有页面都继承自的基页（母版页除外，因为它们具有不同的基类），
然后您可以覆盖基页上的 PreLoad 并在那里进行检查。
I would create a base page that all pages inheriet from (except master pages as these have a different base class)
You could then override PreLoad on the base page and do your checks in there.
您可以创建一个派生自
Page的基类，并具有执行所需操作的Page_Load实现。然后您必须更改所有页面以从这个新基类继承。You could create a base class that derives from
Page, and has an implementation ofPage_Loadthat performs the operations you want. Then you have to change all of your pages to inherit from this new base class.这将是 Global.asax 文件。
That would be the Global.asax file.
