ASP.NET MVC 中的路由错误

Question

我正在尝试从列表中搜索电影。但是，搜索字符串总是 returns null.

我的控制器代码

public ActionResult Index()
{
    return View(db.Movies.ToList());
}

public ActionResult Search(string searchstring)
{

    var movies = from m in db.Movies
                 where m.Title.Contains(searchstring)
                 select m;

    return View(movies.ToList());

}

// GET: Movies/Details/5
public ActionResult Details(int? id)
{
    if (id == null)
    {
        return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
    }
    Movie movie = db.Movies.Find(id);
    if (movie == null)
    {
        return HttpNotFound();
    }
    return View(movie);
}

路由配置

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Movies", action = "Index", id = UrlParameter.Optional }
);

routes.MapRoute(
    name: "Search",
    url: "{controller}/{action}/{searchstring}"
);

我可以从 Index 操作中获取电影列表。我传递的 URL 是 http://localhost:52872/Movies/Search/GodFather

然而，如果我将我的 Search 路线放在 Default 路线之上，它工作正常，但编辑和细节不起作用。

路线冲突。第一个路由模板匹配，因此它不会到达第二个。

出于同样的原因，路由定义的顺序也很重要。

重构为

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

routes.MapRoute(
    name: "Search",
    url: "Movies/Search/{searchstring}",
    defaults: new { controller = "Movies", action = "Search"}
);

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Movies", action = "Index", id = UrlParameter.Optional }
);
