我可以在后台线程中访问会话吗？

Question

How can i access my project sessions in background thread in my c#.net webapplication?

it gives me session value = null.

Any idea?

Answer 1

Threads in the thread pool are managed by the system. These threads are not bound to the current request. Therefore, Session is not available for them.

session lost when multithreading though

Answer 2

You have to be very careful about using background threads with ASP.NET. By the time the thread executes, the "current" request will probably be over. This means you can't access the page, or the request, or anything interesting.

Answer 3

You can't access the session but you could share your data the same way, using: HttpRuntime.Cache

There are a few things to keep in mind though: unlike session, cache do expire. Also the cache is shared between all web users.
