In an HttpModule, I put an Item in the Context, like this:
在HttpModule中,我在上下文中放置了一个Item,如下所示:
HttpContext.Current.Items.Add("MyKey", "Hello world!");
Directly under this code (still inside the module), I can retrieve this string from the collection, so I know it got added.
直接在这个代码下(仍在模块内),我可以从集合中检索这个字符串,所以我知道它已被添加。
Fast forward to my actual handler (a Web form -- .aspx). I try to get this item back:
快进到我的实际处理程序(Web表单 - .aspx)。我试着把这个项目拿回来:
string myString = HttpContext.Current.Items["MyKey"].ToString();
Sadly, it's NULL -- the item is not there.
可悲的是,它是NULL - 项目不在那里。
I spun the collection, and by the time it gets to my handler, the Items collection has two keys:
我旋转了集合,当它到达我的处理程序时,Items集合有两个键:
- AspSession
- AspSessionIDManagerInitializeRequestCalled
After I set the Item in the module, I call RewritePath. Not sure if that has anything to do with it.
在模块中设置Item后,我调用RewritePath。不确定这与它有什么关系。

Not quite clear about the flow of your code but try using HttpContext.Items instead of HttpContext.Current.Items collection. Check out this link - http://odetocode.com/articles/111.aspx
不太清楚你的代码流,但尝试使用HttpContext.Items而不是HttpContext.Current.Items集合。看看这个链接 - http://odetocode.com/articles/111.aspx

My problem was that a redirect snuck in there. So the request where I set the values and the request where I read the values were actually two separate requests. It went so fast that I didn't notice, even when debugging.
我的问题是那里的重定向偷偷摸摸。因此,我设置值的请求和我读取值的请求实际上是两个单独的请求。它进展得如此之快,即使在调试时也没有注意到。
