I have an actionlink that on click im passing a List of objects to a controller action.

Example:

View:

Html.ActionLink("TestLink", "TestMethod", "Test", Model.SampleList, null)

TestController:

public ActionResult TestMethod(List sampleList)
{
return View(sampleList);
}

When I do this I get a null sampleList. I can pass a single complex object fine just not a collection of it. Do I need the correct routing for this? The reason I'm doing this is instead of passing an id and do a look up in the controller action, I just pass in the data.
