Hi,

How can I store a class (including all it's members) in session object?

I already tried something like:

Session["Status"] = myClass;

but it stores the value of myClass.ToString in it!!

Thanks,
Alan
 
The Session object is a collection of -objects-. Any objects, but to
properly use the class after retrieving from the Session, you must cast it
back from an object to its native type:
myClass = (MyType)Session["Status"]; I'm not 100% sure that this is the
problem that you are having, but that is how I use Session to store an
object.

I use Session all the time to store complete objects. It works great.

Than you for help.

The Trace is on for all pages.
How can I see the members of that object in Trace output? Because Trace just
shows the class name (like myClass)!!.

Thanks again,
Alan

You will need to override the .ToString() method for your class. I believe
the trace calls .ToString() on each object in Session, etc.

Yes, that's right. Session stores objects, not just strings, and if you
don't explicitly define a ToString() method, then the one inherited from
Ojbect will be called, and that's not what you want, so override ToString()
and have it return some key information in your object.

Hi Alan,

I've found that there is anothe thread named
"Re: Putting a class in a Session" in the same newsgroup on this issue and
some community member also provide some informative suggestions there. I'd
appreciate if you have a look there. Also, if you feel convenient that we
continue to discuss in that thread, please feel free to followup there.
Thanks.
