C # Syntax sugar session operation class ASP.

Usage:

   Fame a data set            var liststring = new list<string> () {"A", "B", "C"};            Session key            String key = "Sekey";            Get instance            var sessionmanager = Sessionmanager<list<string>>. GetInstance ();            Add session            Sessionmanager.add (key, liststring);            Add has other overloads above is the most basic            //Get            list<string> sessionlist = Sessionmanager[key];            Other methods            Sessionmanager.containskey (key);            Sessionmanager.remove (key);//delete            Sessionmanager.removeall (c = c.contains ("Sales_"));//delete key contains Sales_ Session            Sessionmanager.getallkey ();//Get all keys
