Application_BeginRequest和Page对象 [英] Application_BeginRequest and the Page object

问题描述

是否可以以编程方式访问

Application_BeginRequest中的Page对象，或者在生命周期中是否过早...... ？


例如能够动态更改页面的MasterPage，如：


protected void Application_BeginRequest（Object sender，EventArgs e）

{

if（Session [" LoggedOn"] ==" True"）

{

< page> .MasterPageFile ="〜/ loggedOn .master" ;;

}

其他

{

< page> .MasterPageFile ="〜/ notLoggedOn.master" ;;

}

}


NB我意识到有可能以其他方式实现上述功能......这只是一个假设的例子......


感激的任何帮助收到。

Hi,

Is it possible to have programmatic access to the Page object in
Application_BeginRequest, or is it too early in the lifecycle...?

E.g. to be able to change a page''s MasterPage dynamically, something like:

protected void Application_BeginRequest(Object sender, EventArgs e)
{
if (Session["LoggedOn"] == "True")
{
<page>.MasterPageFile = "~/loggedOn.master";
}
else
{
<page>.MasterPageFile = "~/notLoggedOn.master";
}
}

N.B. I realise it''s possible to achieve the above functionality in other
ways - it''s just a hypothetical example...

Any assistance gratefully received.

问题是针对* all *的请求引发了Application_BeginRequest事件。


你确定要的是那个代码每次您的应用程序收到请求时执行？


查看应用程序生命周期概述：
http://msdn2.microsoft.com/en-us/library/ms178473.aspx

和ASP.NET页面生命周期概述，位于：
http://msdn2.microsoft.com/en-us/library/ms178472.aspx


我敢肯定你''在这两页中的一页中找到更合适的应用程序或页面，

事件代码。

The problem is that the Application_BeginRequest event is raised for *all* requests.

Are you sure you want that code to execute every time your application receives a request?

Check out the Application Lifecycle Overview at :
http://msdn2.microsoft.com/en-us/library/ms178473.aspx

and the ASP.NET Page Life Cycle Overview, at :
http://msdn2.microsoft.com/en-us/library/ms178472.aspx

I''m sure you''ll find a more appropiate application, or page,
event for that code in one of those two pages.

requests.

这是对的。

That''s right.

你确定你希望每次你的代码都执行申请

收到请求？

Are you sure you want that code to execute every time your application
receives a request?

谁知道 - 只是有兴趣知道，因此假设位... :-)


有可能吗？

Who knows - was just interested to know, hence the "hypothetical" bit... :-)

Is it possible?
