Session variables converter?

[Trebor100]

Morning all,

I'm in need of some help with something I really should know but for the life of me I can't get to work!!!

I'm trying to pass a list of file uploaders into and out of a session variable. ie:

private List<FileUpload> files;

Session["files"] = List;

List = Session["files"];

Error will be on the List = Session["files"];
I'm thinking i need to use the converter as its not a base class but cannot figure the syntax.

Any help much appricated as I'm googling like a headless chicken on curry night!

correction on my quick typing of current state:
private List<FileUpload> files;
Session["files"] = files;
files= Session["files"];

It should be something like;

private List<FileUpload> files;
Session["files"] = files;
files= Session["files"] as List<FileUpload>;

...or;

private List<FileUpload> files;
Session["files"] = files;
files= (List<FileUpload>)Session["files"];

NB: I have not tried this, just attempting to recall it from memory

the syntax is correct, but why would you load UI controls in and out of session? that doesn't make sense.
instead, store the required data in session, using a DTO if necessary, and recreate the controls with each request.
