You can comma or pipe delimit your input and on the other end just parse it to keep things simple. Or if you want to do things the right object oriented way you could use the following code:
var object1 = $(".ControlArrayClass").val();
var object2 = $(".ControlArrayClass2").val();
$.post('mycontroller/myactionmethod', function( variable1: object1, variable2: object2});
and on the controller end it would look like this
public ActionResult myactionmethod(Guid[] variable1, String[] variable2)
{
//do whatever here
return View();
}
Hope this helps.
