Can you give more info on what your trying to store? Regardless as
always, you can throw all your stuff in the viewstate. The tradeoff is
performance.

Well,for example,I declare a Queue<string> RecentUploadFiles as the
class member field in .aspx.cs file,want it store recent uploaded file
infomation,one by one.

But now,every time I upload one file,this Queue has only one string,the
newest one.So,it must be re-created at every post-back,all other old
values are missed. We can see this is not what I want.Any idea?

Thank you very much,dear Joe.

hmmm. If I understand you correctly you probably dont want this info to
be lost when they click their back button. So, mabey this list should be
stored in a session variable?

Session["recentuploadFiles"] = x;

No,I just want the value keeping btween post back at the same aspx
page,instead of cross-aspx page.
