asp.net-mvc - 从 ActionFilter 重定向到 Action

Question

如何从自定义 ActionFilter 访问 RedirectToAction？

public class ExceptionHandlingFilterAttribute : ActionFilterAttribute
{
    public override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        if (filterContext.Exception != null && !filterContext.ExceptionHandled)
        {
            filterContext.ExceptionHandled = true;

            // HERE : RedirectToAction("ServiceNotFound","Error");

        }
        base.OnActionExecuted(filterContext);
    }   
}

试试这个:

filterContext.Result = new RedirectToRouteResult(
    new System.Web.Routing.RouteValueDictionary {
        {"controller", "Error"}, {"action", "ServiceNotFound"}
    }
);
