Uniform way of passing an array in querystring in ASP.NET MVC 4

Question

I have a controller's action:

public ActionResult Find(IEnumerable<string> ids) { ... }

I'm succesfully invoking it by route ../Find?ids=01&ids=02&ids=03. DefaultModelBinder easily binds the parameter with no extra configuration. However, when I'm trying to do outbound routing, i.e. use code like this in my View

@Url.Action("Find", "Grid", new {ids=new List<string>{01,02,03}})

.. I'm getting a nice ..?ids=System.Collections.Generic.List1[System.String] querystring in my URL. I've already found some answers which suggest writing an custom binding/routing, but I believe such a simple task should be solved much easier without any extra code.

P.S.: I'd be perfectly happy to change my querystring format, I just want to rely on some default framework behavior to accomplish the task: pass an array in querystring.

Short version: what is the most simple way to render a link to a controller's action with an array in querystring?

its not elegant way... but simple and fast. Try

@Url.Action("Find", "Grid", new {ids= string.Join("&ids=", YourList)})

thanks, but it's exactly the kind of code I'm trying to avoid :) it always seems veery weird to me when you have to use hacks like this for something I'd call a "basic typical task".
