Redirect to unauthorized controller action on OnAuthorization

Redirecting unauthorized controller in ASP NET MVC

Hello everyone, I am going to share the code sample to Redirect to unauthorized controller action on OnAuthorization using  ASP.NET MVC. i.e.

filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary { { "Controller", "Error" }, { "Action", "AccessDenied" } });   
base.OnAuthorization(filterContext);//returns to AccessDenied page URL.     


The detail code sample as given below

namespace Authorization.Models
{
    public class CustomAuthorizeAttribute : AuthorizeAttribute
    {
        public override void OnAuthorization(AuthorizationContext filterContext)
        {
            AspDotNetUserRepository _aspNetRepo = new AspDotNetUserRepository();
            if (filterContext.HttpContext.Request.IsAuthenticated)
            {              
                    if (!String.IsNullOrEmpty(userRole))
                    {
                        if (!userRole.Equals(Roles))
                        {
                            filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary { { "Controller", "Error" }, { "Action", "AccessDenied" } });   
                            FormsAuthentication.SignOut();
                            base.OnAuthorization(filterContext);//returns to AccessDenied page URL.     
                        }
                    }
                }
            }
        }
    }
