Member 'object.Equals(object, object)' cannot be accessed with an instance reference; qualify it with a type name instead

Question

When I used the following code in C#...

int totalValue = 0;
int total = 0;
totalValue = int.Parse(Session[\"price\"].ToString()) * int.Parse(Session[\"day\"]         


        

Answer 1

Your code is not strong.

Session is an object, it can be null, so if you want to use its value, please check the session first, and even the session's value is not a integer value.

I suggest you to do like this:

int? i = Session["s"] == null ? null : Parser.ParseInt(Session["s"].ToString());
