如何让过滤器重定向到另一个动作？

RedirectToAction只是一个构造a的辅助方法RedirectToRouteResult(),所以你所做的只是创建一个新的RedirectToRouteResult()传递RouteValueDictionary()带有值的动作.

根据以下评论中@Domenic的代码完成示例:

public class IsGuestAttribute: ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        if (!Ctx.User.IsGuest) 
        {
            filterContext.Result = new RedirectToRouteResult(
                new RouteValueDictionary 
                { 
                    { "controller", "Home" }, 
                    { "action", "Index" } 
                });
        }
    }
}

这是一个代码示例:

public override void OnActionExecuting(ActionExecutingContext filterContext)
{

    if (!Ctx.User.IsGuest)
    {
        RouteValueDictionary redirectTargetDictionary = new RouteValueDictionary();
        redirectTargetDictionary.Add("action", "Index");
        redirectTargetDictionary.Add("controller", "Home");

        filterContext.Result = new RedirectToRouteResult(redirectTargetDictionary);
    }
}

或者只是`new RedirectToRouteResult(new RouteValueDictionary {{"controller","Home"},{"action","HomePage"}})
