MVC Filter Build member is logged in

Use of the environment: in the background management or the front desk has a member center in the case of use

Usage: This is a User Center controller I add a feature to the User Center home page

[Accountfilter] This is the name of a filter

 Public class Accountcontroller:controller    {        [accountfilter]        public  actionresult Index ()        {            return  View ();        }    }

Filter specific code is as follows

namespacefytmsys.helper{/// <summary>    ///Foreground User Login filter/// </summary>[AttributeUsage (attributetargets.all, AllowMultiple =true)]     Public classAccountfilterattribute:actionfilterattribute { Public stringMessage {Get;Set; }        Filtercontextinfo _fcinfo; //called by the ASP.

Replace ('/', ').                Trim (); //Get controllername nameControllername = filtercontext.routedata.values["Controller"].                ToString (); //get the action nameActionName = filtercontext.routedata.values["Action"].                ToString (); #endregion            }            /// <summary>            ///Get domain name/// </summary>             Public stringDomainName {Get;Set; } /// <summary>            ///Get module name/// </summary>             Public stringModule {Get;Set; } /// <summary>            ///Get controllername name/// </summary>             Public stringcontrollername {Get;Set; } /// <summary>            ///get the action name/// </summary>             Public stringActionName {Get;Set; } }    }}

I used the OnActionExecuting override method, which means that the filter is called before executing the method

Determine if the user is logged in, if not logged in, jump directly to the login page

is not very simple, do not know how security, I am also the first time to use
