I want to set up a ASP.NET MVC route that looks like:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{idl}", // URL with parameters
new { controller = "Home", action = "Index", idl = UrlParameter.Optional } // Parameter defaults
);
That routes requests that look like this...
Example/GetItems/1,2,3
...to my controller action:
public class ExampleController : Controller
{
public ActionResult GetItems(List<int> id_list)
{
return View();
}
}
The question is, what do I set up to transform the idl
url parameter from a string
into List<int>
and call the appropriate controller action?
I have seen a related question here that used OnActionExecuting
to preprocess a string, but did not change the type. I don't think that will work for me here, because when I override OnActionExecuting
in my controller and inspect the ActionExecutingContext
parameter, I see that the ActionParameters
dictionary already has an idl
key with a null value- presumably, an attempted cast from string to List<int>
... this is the part of the routing I want to be in control of.
Is this possible?
