ASP。NET MVC路由的字符串id?

In ASP.NET 2, how do I create a route that allows lookup of an object (eg Product) by a string id (eg ProductCode)? The route for looking up the same object by it's integer id (eg ProductId) is automatic, so I don't actually know how it works.

在ASP。NET 2，如何创建允许通过字符串id(如ProductCode)查找对象(如产品)的路由?通过它的整数id(如ProductId)查找同一对象的路径是自动的，所以我实际上不知道它是如何工作的。

The automatic route by id is:

id自动路由为:

/Product/1

How do I also create a 2nd route that uses a string id?

如何创建第二个使用字符串id的路由?

/Product/red-widget

And how do I do it so that both routes are available?

我要怎么做才能让两条线路都畅通?

You should take a look at using a route constraint to do this. See http://www.asp.net/mvc/tutorials/creating-a-route-constraint-cs

您应该了解如何使用路由约束来实现这一点。参见http://www.asp.net/mvc/tutorials/creating-a-route-constraint-cs

routes.MapRoute(
    "Product",
    "Product/{productId}",
    new {controller="Product", action="DetailsByName"},
    new {productId = @"\w+" }
 );

In the above, the constraint regex "\w+" should limit to routes that match only "word" characters (take a look at regex docs for more details on patterns used here).

在上面，约束regex“\w+”应该限制为只匹配“word”字符的路由(有关这里使用的模式的更多细节，请参阅regex文档)。
