添加一个通配符路由规则作为最终的规则：

Add a wildcard routing rule as your final rule:

routes.MapRoute("Error", 
                "{*url}", 
                new { controller = "Error", action = "Http404" });

这不符合其他规则的任何请求被路由到错误控制器的HTTP404行动，您还需要配置：

Any request that doesn't match another rule gets routed to the Http404 action of the Error controller, which you also need to configure:

public ActionResult Http404(string url) {
    Response.StatusCode = 404;
    ViewData["url"] = url;
    return View();
}
