Routing question with MVC 3 and razor

I want my route to look like this:

/Products/Image11_full.jpg

My Razor looks like this:

<a rel="pgroup" title="@image.Name" href="@Url.RouteUrl("Image", new { controller = "Products", action = "Image", imageId = image.ImageId, size = "full" })" >

My route looks like this:

routes.MapRoute(
            "Image",
            "Products/Image{imageId}_{size}.jpg", // URL pattern, e.g. ~/Products/Image/
            new开发者_如何学运维 { controller = "Products", action = "Image" }, // Defaults will also match "GetSmallImage"
            new { imageId = @"\d+", size = @"\(full\|small\|medium\)" }
            );

I ether don't get anything (when I use a route name) or I get a route that look like this /Products/Image?imageId=11&size=full which means it didn't find my route.

Anyone see what I'm doing wrong?

Thanks Irv

Your size constraint is not correct. Define it like this:

routes.MapRoute(
            "Image",
            "Products/Image{imageId}_{size}.jpg", // URL pattern, e.g. ~/Products/Image/
            new { controller = "Products", action = "Image" }, // Defaults will also match "GetSmallImage"
            new { imageId = @"\d+", size = @"full|small|medium" }
            );

Remove controller and action from the RouteUrl call. (Since they aren't in the URL parameters)
