Session object changes when object is updated in C#

Question

I have this really weird problem and I\'m sure I\'m missing something obvious here. I have these two lines:

HttpContext.Current.Session[listModelType + \"Lis         


        

Answer 1

In the first example your session variable is pointing to a reference so it gets updated because the two references are pointing to the same value.

The second session variable is pointing to a primitive (value) type so they have separate copies of value.
