session from ServicedComponent

[Kevin Jackson]

If we are using Library ServicedComponents is it possible to get to the
ASP.NET session stuff from a ServicedComponent?

Hi Kevin,


Thanks for posting in the community!
From your description, you wonder if there is any means to access the
ASP.NET's sessionstate in custom ServicedComponent rather than
PageComponent ,yes?
If there is anything I misunderstood, please feel free to let me know.

As for this problem, I think there're two means to use the ASP.NET buildin
objects in a certain library component.
1. Define a certain parameter type of which is one of the ASP.NET buildin
class(such as SessionState, HttpRequest, HttpResponse..). For example:
class component
{
public static void processSession(HttpSessionState session)
{
........
}
}

2. Since the #1 means is limited us to pass a certain object reference to
the component's method, it need us to explicitly use it and set the
parameter in Page's certain events. However, there is another means :
using the HttpContext class , the HttpContext has a static member "Current"
which is the refernce of the currently processed request's HttpContext,
here is the description in MSDN:
-----------------------
You can also use the Context object from your business objects.
HttpContext.Current is a static property that conveniently returns the
context for the current request. This is useful in all kinds of ways, but
here's a simple example of retrieving an item from the cache in your
business class:
--------------------------------
So we can use it to retrieve the current processing request's Request,
Response, Session ... objects in our business components, for example
class component
{
public void processSession()
{
HttpSessionState session = HttpContext.Current.Session;
....
........
}
}

For detailed description, you can view the following tech article in MSDN:

In addition, here is another tech article discussing the designer pattern
in ASP.NET, I believe it also helpful to you.

Please check out the above suggestions. If you have any questions, please
feel free to let me know.
