I want to pass a list array from the View to the controller on submission of the form. I can pass back simple values by using the Html.hidden() function. But how does one pass back a complex object or a List array

You can either use Json or look into the following example

You can pass back a list within a view model using Html.hidden for each element of a list.
The list property in your view model will be re-constructed as long as you process the list elements using a for loop in your view (foreach will not work). For example:
@for (var i = 0; i < Model.Nutrients.Count(); i++)
{
// This ensures that the list of nutrients is passed in the view model back to the controller
@Html.HiddenFor(m => m.Nutrients[i].Name);
@Html.HiddenFor(m => m.Nutrients[i].Id);
}
