全局修改MVC中生成的url

掌握路由:

http://www.asp.net/mvc/tutorials/older-versions/controllers-and-routing/asp-net-mvc-routing-overview-cs

路由在全局路由中找到。asax文件和像ActionLink这样的htmlhelper应该自动适应你的自定义路由。如果在默认路由之上指定一个自定义路由，然后执行以下操作，生成的URL将与路由匹配:

@Html.ActionLink("Go!", "AnAction", "AController")

如果您在路由中指定的其他参数不能作为ActionLink标准过载的参数，则可以在routeValues参数中传递这些参数:

@Html.ActionLink("Go!", "AnAction", "AController",
    new { MyCustomParameter = "Hello" })

这就是我解决问题的方法。它允许在区域和默认routecconfig中注册"SEO"路由。

修剪过程不是很成熟，但这只是为了演示。
