You can't change the variable directly. But you can use Session to achieve this.

In Page 1

Session["session-name"] = "5";

In Page 2

      if (Session["session-name"] != null) // check the session if it is exist
            {
                int a;
                try
                {
                    a = int.Parse(Session["session-name"].ToString());
                }
                catch
                {
                    a = 0; // you can set null too. Whatever you want
                }
            }

You likely want to use Session Variables. You can start learning here.
