RedirectToRoute不起作用

Question

我正在制作我的第一个网络应用。到目前为止，我没有遇到redirectToRoute或redirectToAction的任何问题。在帖子操作结束时，我想重定向，但它根本不起作用，这是我的代码：

   [HttpPost]
    public ActionResult Delete(int id)
    {
        var post = this.Data
            .Posts
            .All()
            .Where(x => x.Id == id)
            .FirstOrDefault();

        if (post != null)
        {
            var thread = this.Data
                .Threads
                .All()
                .Where(x => x.Id == post.ThreadId)
                .FirstOrDefault();

            this.Data
                .Posts
                .Delete(post);

            this.Data.SaveChanges();

            return this.RedirectToRoute(CommonConstants.RedirectToRouteShowThread, new
            {
                area = "",
                id = thread.Id,
                title = thread.SubCategory.Title,
                name = thread.Title,
                action = "Display"
            });
            //return this.RedirectToRoute(CommonConstants.RedirectToRouteShowAllThreadsInSubCategory, new { Area = "", title = thread.SubCategory.Title });

            // return this.Redirect("red/red");
        }

        return this.View();
    }

我也尝试了不同的重定向测试，但仍然无效。如果重要，我会从js调用此动作。我也检查了它是否进入内部如果有条件，一切似乎都很好。我的错误在哪里？

编辑：这是我的路线

     public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Show thread",
            url: "SubCategory/{title}/{action}/{id}-{name}/{page}",
            defaults: new { controller = "Post", action = "Display", page = UrlParameter.Optional },
            namespaces: new[] { "ForumSystem.Web.Controllers" });

        routes.MapRoute(
            name: "Create and display threads",
            url: "SubCategory/{title}/{action}/{page}",
            defaults: new { controller = "SubCategory", page = UrlParameter.Optional },
            namespaces: new[] { "ForumSystem.Web.Controllers" });

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
            namespaces: new[] { "ForumSystem.Web.Controllers" });
    }

这是const

    public static readonly string RedirectToRouteShowThread = "Show thread";

我的意思是它不起作用是它没有重定向所有其他工作按预期工作。
