Can I modify ASP.NET session object this way?

Question

Imagine that I have an instance (oEmp) of "Employee" class and I would like to store it session.

Session["CurrentEmp"] = oEmp;

If I modify a property in oEmp as follows:

oEmp.Ename = "Scott";

Am I referring to session item through above statement or just only "oEmp"?

Session["CurrentEmp"] = oEmp; //Do we still need this after any property is modified

Is that the same case, if I opted for SQL Server session state (instead of InProc).

thanks

Answer 1

Asp.net Session will hold the reference, so you shouldn't need to do the following:

Session["CurrentEmp"] = oEmp;

after modifying oEmp;

Answer 2

Session Variables are held as reference types so there is no need to update its value every time.
You object instance that you store, only the reference to that object is stored in the session variable.

Do asp.net application variables pass by reference or value?
