MVC路由多参数传递问题,请大伙帮忙

Question

设置路由如下:
MapRoute(
                "NewsList",
                "News/List/{NewTypeId}/{*values}",
                new { controller = "News", action = "List" }
            );
如果我传入三个参数,
我希望出来的URL是这样:News/List/China/2008/01但实际出来的结果却是:News/List/China/?year=2008&year=01不知道是不是设置错误,请高手帮忙

Answer 1

这个原因是因为你Route放置顺序不对引起的。下面这样放正常，会生成你想要的格式http://10.0.0.69:70/news.ashx/newlist/2008/1            routes.MapRoute(
                "news",
                "news.ashx/newlist/{year}/{day}",
                new { controller = "news", action = "newlist", year = "year", day = "year" }
                );            routes.MapRoute(
                "Default",                                              // Route name
                "{controller}.ashx/{action}/{id}",                           // URL with parameters
                new { controller = "Home", action = "Index", id = "" }  // Parameter defaults
            );
如果是这样放，格式就成了http://10.0.0.69:70/news.ashx/newlist?year=2008&day=1            routes.MapRoute(
                "Default",                                              // Route name
                "{controller}.ashx/{action}/{id}",                           // URL with parameters
                new { controller = "Home", action = "Index", id = "" }  // Parameter defaults
            );
            routes.MapRoute(
                "news",
                "news.ashx/newlist/{year}/{day}",
                new { controller = "news", action = "newlist", year = "year", day = "year" }
                );

Route 是按顺序进行匹配的，能匹配第一条，下面就不在匹配，所以进行URL重写要注意匹配顺序。
