I have an action defined like so:

public ActionResult Foo(int[] bar) { ... }

Url's like this will work as expected:

.../Controller/Foo?bar=1&bar=3&bar=5

I have another action that does some work and then redirects to the Foo action above for some computed values of bar.

Is there a simple way of specifying the route values with RedirectToAction or ActionLink so that the url's get generated like the above example?

These don't seem to work:

return RedirectToAction("Foo", new { bar = new[] { 1, 3, 5 } });
return RedirectToAction("Foo", new[] { 1, 3, 5 });

<%= Html.ActionLink("Foo", "Foo", new { bar = new[] { 1, 3, 5 } }) %>
<%= Html.ActionLink("Foo", "Foo", new[] { 1, 3, 5 }) %>

However, for a single item in the array, these do work:

return RedirectToAction("Foo", new { bar = 1 });
<%= Html.ActionLink("Foo", "Foo", new { bar = 1 }) %>

When setting bar to an array, it redirects to the following:

.../Controller/Foo?a=System.Int32[]

Finally, this is with ASP.NET MVC 2 RC.

Thanks.
