C# - Using a copy of Session-stored variables instead of reference

session

I have an asp:ImageButton with OnClick="Btn_OnClick".
In Btn_OnClick I have this line:

DataTable dtTable = (DataTable)Session["someSessionKey"]

and dtTable is altered in the function.

I've noticed that if the button's clicked more than once, the dtTable I take from the session contains the altered table, probably meaning dtTable is not a copy but a reference of the session variable.

How can I alter a copy of Session["someSessionKey"], and not the actual value?
Thanks!

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.
