Html.Actionlink与ID [英] Html.Actionlink with ID

问题描述

我有这样的code：

@Html.ActionLink("Back To Blog","Blog","Home", new {Model.BlogId}, null)

这code是产生此HTML：

That code is generating this HTML:

<a href="/Home/Blog?BlogId=1">Back To Blog</a>

但我想它生成的是这样的：

<a href="/Home/Blog/1">Back To Blog</a>

我该如何解决这个问题？

How do I fix this?

PS - 我看到了SO这个帖子这似乎表明我做了正确的方式，但我没有得到我想要的结果。我使用MVC4，最新的版本。

PS - I saw this post on SO which seems to indicate I'm doing it the right way, but I am not getting the results I want. I am using MVC4, latest version.

推荐答案

我怀疑你没有配置为路线主页/博客/ {BlogId} 。因此，如果你希望能够写这个（如你在code显示）：

I suspect you don't have a route configured for Home/Blog/{BlogId}. So if you want to be able to write this (as what you show in your code):

@Html.ActionLink("Back To Blog","Blog","Home", new { Model.BlogId}, null)

您需要有一个这样的路线：

You need to have a route like this:

routes.MapRoute(
    name: "DefaultBlog",
    url: "{controller}/{action}/{blogid}",
    defaults: new { controller = "Home", action = "Blog", 
            blogid = UrlParameter.Optional }
);

注意被命名为URL的第三部分 blogid 。但是，如果你不想配置其它路由那么你可以重写你的链接为：

Notice the third part of the url which is named blogid. But if you don't want to configure another route then you can just rewrite your link as:

@Html.ActionLink("Back To Blog","Blog","Home", new { id = Model.BlogId}, null)

注意 ID 的参数。
