超文本标记语言ActionLink包含额外参数

Question

使用以下代码:

@Html.ActionLink("News", "Index", new { controller = "News", area = "" }, new { @class = "News" })

我得到一个错误，所以当我在一个特定的新闻文章，链接生成为:

http://mywebsite/News/2011/12/2/my_slug

，其中参数与我当前所在的页面匹配。在匹配相同url模式的其他控制器上也会发生这种情况(假设我有另一个名为Presentations的控制器，它完全匹配News的url模式)。从演示页面，到新闻的链接将包括演示参数，这些参数不是新闻控制器的有效输入。有意义吗?

我的路由定义为:

        routes.MapRoute(
            "News-Archive", // Route name
            "News/Archive", // URL with parameters
            new { controller = "News", action = "Archive" }, // Parameter defaults
            new[] { "mywebsite.Controllers" }
        );
        routes.MapRoute(
            "News-Stub", // Route name
            "News/{year}/{month}/{date}/{slug}", // URL with parameters
            new { controller = "News", action = "Index" }, // Parameter defaults
            new[] { "mywebsite.Controllers" }
        );
        routes.MapRoute(
            "News-ByDay", // Route name
            "News/{year}/{month}/{day}", // URL with parameters
            new { controller = "News", action = "Archive" }, // Parameter defaults
            new[] { "mywebsite.Controllers" }
        );
        routes.MapRoute(
          "News-ByMonth", // Route name
          "News/{year}/{month}", // URL with parameters
          new { controller = "News", action = "Archive" }, // Parameter defaults
          new[] { "mywebsite.Controllers" }
        );
        routes.MapRoute(
          "News-ByYear", // Route name
          "News/{year}", // URL with parameters
          new { controller = "News", action = "Archive" }, // Parameter defaults
          new[] { "mywebsite.Controllers" }
        );
        routes.MapRoute(
          "News-Default", // Route name
          "News", // URL with parameters
          new { controller = "News", action = "Index" }, // Parameter defaults
          new[] { "mywebsite.Controllers" }
        );

有人可以解释如果问题在于我使用Html。ActionLink还是我的路由定义?

编辑:

将Actionlink更改为:

@Html.ActionLink("News", "Index", new { controller = "News", area = "", year = string.Empty, month = string.Empty, day = string.Empty, slug = string.Empty}, null)

当从演示页面调用

时(这些值用于演示，而不是有效的新闻项):

http://mywebsite/News?year=2011&月= 12,蛞蝓= seo_overview

不知道为什么会导致重写发生变化

Answer 1

动作链接假定为当前的段塞，因为没有提供段塞:

使用

 ActionLink("News", "Index", new { controller = "News", area = "", slug="newslug"}, new { @class = "News" })

或

 ActionLink("News", "Index", new { controller = "News", area = "", slug = null}, new { @class = "News" })

设置slug = null也有可能重用当前的slug，在这种情况下设置slug = Empty String
