Question

I know that the first route will catch most of the paths. However, this will catch also /Product/Edit/blablabla (i’m using ASP.NET Routing Debugger):

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Default", 
            "{controller}/{action}/{id}",                          
            new { controller = "Home", action = "Index", id = @"\d{1,}" }
        );

        routes.MapRoute(
            "Catch All",
            "{*path}",
            new { controller = "Error", action = "NotFound" }
        );
    }

But this is wrong! Why? If not an integer of min 1 of length, the first route should not match. I need also to handle not found coutroller and action… any ideas?

Many thanks!

You should place expression in fourth parameter. Read this:

http://www.asp.net/LEARN/MVC/tutorial-24-cs.aspx

Listing 3.

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

The regular expression \d+ matches
one or more integers. This constraint causes the Product route to match
the following URLs:

• /Product/3
• /Product/8999

But not the following URLs:

• /Product/apple
• /Product

These browser requests will be
handled by another route or, if there are no matching routes, a The
resource could not be found error will be returned.
