MapRouting默认查询字符串值？ [英] MapRouting default querystring values?

问题描述

我有这个路线图（请注意，topicName被忽略）：

I have this route map (notice that topicName is ignored):

routes.MapRoute(
                "Topics", // Route name
               "Topic/{topicName}/{action}",
                new { controller = "Topic", action = "AddQuestion" });  

和我希望它defaultly映射到以下链接：
的http：//本地主机：51421 /主题/ SomeName / AddQuestion topicId = 1 （如果这是不可能的，这个网址：的http：//本地主机：51421 /主题/ SomeName / AddQuestion / topicId / 1 ）结果
（这应该调用这个动作：

And I want it to defaultly map to this Url: http://localhost:51421/Topic/SomeName/AddQuestion?topicId=1 (or if that's not possible,to this url: http://localhost:51421/Topic/SomeName/AddQuestion/topicId/1)
(which should invoke this action:

public ActionResult AddQuestion(int topicId)
        {
            return View();
        }  

）结果
但无论哪种方式，我需要在URL中所有数据。结果
什么是做到这一点的正确方法？

)
But either way I need all this data in the url.
What's the correct way to do that?

推荐答案

您可以添加一个默认的路由：

You could add a default route:

routes.MapRoute(
    "Topics",
    "Topic/{topicName}/{action}/{topicId}",
    new { controller = "Topic", action = "AddQuestion", topicId = "1" }
);

routes.MapRoute(
    "Default",
    "{controller}/{action}/{topicId}",
    new { controller = "Topic", action = "AddQuestion", topicId = "1" }
);
