从.NET类访问内部ASP（不是ASP.NET）对象 [英] Accessing intrinsic ASP (not ASP.NET) objects from .NET class
问题描述
是否可以从.NET
类访问内部ASP对象，例如Request。说，我有一个通过COM或COM +包装器公开的.NET库。可以
这个库检索请求信息（基本上，服务器变量通过Request对象暴露
），当它从传统ASP调用时（不是
ASP.NET）应用程序？有任何想法吗？在此先感谢。

您可以尝试System.Web.HttpContext.Current.Request（.Current可能不会需要
等等，但我不知道是否转移了这个上下文并且可以在ASP.NET中正确读取
。从来没有在我自己之前完成这个，所以，只需要尝试一下......

不，这不起作用。 Current.Request尝试检索ASP.NET应用程序的内部
对象，因此当从ASP应用程序调用它时，
将其值设置为NULL。据我所知ASP和ASP.NET使用不同的
内在对象。必须有办法做到这一点。感谢
的建议。

没有。因为你的.net类是从asp调用的，而不是aspx，没有.net
请求对象或流。
backgroup，在aspx中，asp运行在一个单独的过程中，并使用命名管道
与iis进程进行通信。 .net响应对象写入此
管道。显然，如果你的.net对象是由asp托管的，那么这个管道就不存在
了。
你需要在你的asp类中添加一个方法可以注册基于
com的Request对象，因此.net代码可以与它通信。

Hi,
Is it possible to access intrinsic ASP objects, such as Request, from a .NET
class. Say, I have a .NET library exposed via a COM or COM+ wrapper. Can
this library retrieve the request info (basically, server variables exposed
via the Request object), when it is invoked from a traditional ASP (not
ASP.NET) application? Any ideas? Thanks in advance.

You can try System.Web.HttpContext.Current.Request (.Current may not be
needed), etc., but I don''t know if that context is transferred and can
be read correctly in the ASP.NET. Never done this before myself, tho,
just something to try...

No, this does not work. Current.Request attempts to retrieve the intrinsic
object of ASP.NET application, so when it is called from an ASP application,
its values is set to NULL. As I understand ASP and ASP.NET use different
intrinsic objects. There must be a way of doing this. Thanks for the
suggestion, though.

no. because your .net class is called from asp, not aspx, there is no .net
request object or stream.
backgroup, in aspx, asp runs in a seperate process, and uses a named pipes
to communicate to the iis process. the .net response object writes to this
pipe. obviously if you .net object is hosted by asp, this pipe does not
exist.
you will need to add a method to you class where the asp can register the
com based Request object, so the .net code can talk to it.
