    public class appcore     {               private static idictionary<string, string> dlink = new dictionary<string, string>();      static appcore()     {       //app links         dlink.add("js", "~/_assets/js/");         dlink.add("css", "~/_assets/css/");         dlink.add("img", "~/_assets/img/");     }           public static string link(string i)     {         if (!dlink.containskey(i))             return "n/a";         else             return dlink[i];     } }
