Hello,
I have created ASP.NET project in which I have a file Admin.cs. It contains
static class Admin with some methods and properties. The problem is that in
property get a reference HttpContext.Cur rent.Session is null, although for
instance HttpContext.Cur rent.Applicatio n or HttpContext.Cur rent.Request is
not null:
public static class Admin
{
...
set
{
HttpContext.Cur rent.Session["Database"] = value; // HERE OK
}
get
{
object db = HttpContext.Cur rent.Session["Database"]; // HERE PROBLEM
if (db == null)
return null;
return db.ToString();
}
...
}
Could anyone explain me why? How to use Session object in my code?

Have you debugged the code and verified that it's actually the reference
to the Session object that is null, and not simply that the Items
collection doesn't contain the key "Database"?

Yes, I debugged the code. HttpContext.Cur rent.Applicatio n,
HttpContext.Cur rent.Cache, HttpContext.Cur rent.Response,
HttpContext.Cur rent.Request are not null, they reference valid object. Only
HttpContext.Cur rent.Session is null.
It looks strange for me, so I have sent the post.
Could you help me?

I have forgotten to add: I changed web server from IIS 5.1 to Cassini 2.
Generally Cassini works fine, but maybe that's the reson why Session doesn't
work... I cannot use IIS because I had interal error in IIS and I failed to
solve the problem.

No, that's not the reson. I have learnt that Cassini supports Session
object.

In your code you indicated that the Session object existed when you set
the session variable, but not when you read it? It doesn't make sense
that the existance of the Session object would be different depending on
if you try to read or write a value. Where do you use the property? When
does the Session object exist?
The web site can have session state enabled or disabled, but that is a
global setting for the site. If disabled, there won't be any Session
objects at all.

I have learnt that accessibilty of HttpContext.Cur rent.Session may depend on
the place I use Admin...get.
But in my project it is Default.aspx page (startup), method Page_Load
(code-behind). So I have a question: should HttpContext.Cur rent.Session be
accessible in this place?

I use set/get in code-behind of Default.aspx.

objects at all.
I have session enabled in my web.config:
<sessionState mode="InProc" timeout="20" />

If the session state is disabled in IIS, the setting in web.config
doesn't have any effect.

There is only a HttpContext if the code is executed to handle a request.
The Application_End event for example is not executed to handle a
request, and doesn't have a HttpContext.
But in my project it is Default.aspx page (startup), method Page_Load
(code-behind). So I have a question: should HttpContext.Cur rent.Session be

Yes. If session state is enabled for the site.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
