C # syntax sugar cookie Operation class ASP.

Usage:

   Fame a data set            var liststring = new list<string> () {"A", "B", "C"};            Cache key            String key = "Cokey";            Get instance            var cookiesmanager = Cookiesmanager<list<string>>. GetInstance ();            Insert Cache            Cookiesmanager.add (key, liststring, Cookiesmanager.minutes * 30);//Expires 30 minutes             //add has other overloads above is the most basic            // Get            list<string> cookieslist = Cookiesmanager[key];            Other methods            Cookiesmanager.containskey (key);            Cookiesmanager.remove (key);//delete            Cookiesmanager.removeall (c = c.contains ("Sales_"));//delete key contains Sales_ The cookie            cookiesmanager.getallkey ();//Get all keys
