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 your first example you are storing a reference to the object (The lists memory location). So if the list is updated it will reflect in the session. This is a reference type.

In the second example you are using a value type:

int i = 0;
HttpContext.Current.Session["i"] = i;
i++;

You declare i and set it to 0 (Value type)

You store the value 0 in the session. (Not the memory location of i)

You increment i but the session still has the value 0
