how to pass a string array into actionresult

Question

I have a variable that is a string[] parameter. I've tried to push values in the actionresult and have yet to match the string[] parameter. So my ajax:

    var panels = [];
    $('input.checkone').each(function (e) {
        if ($(this).is(':checked')) {
            var inputCheck = $(this).closest('tr').find('td:nth-child(6) a').text();
            panels.push(inputCheck);
        }
    });
    var data = { panels: panels };
    $.ajax({
      url: "/main/sub",
      data: data,
    }).etc...

So panels looks like panels: Array[1] 0:'test', and it goes to my controller:

public ActionResult sub(string[] panels)
{
 //content 
}

Currently the panels is going through like {string[1]}. I'm not sure why my strings aren't being passed in correctly and its being passed like {string[1]}.

it seems like its passing ok in the jQuery, it gets the text, but when I pass it to my controller it gets replaced with {string[1]} — Keith

This code works for me:

        var url = 'http://my-address/';
        var array = ["hello", "world"];
        $.post(url, $.param({ data: array }, true), function (result) {
            $('#MyDiv').html(result);                
        }); 



public ActionResult sub(List<string> data)
{
 //content 
}

You need to tell jQuery to serialize your parameters in the traditional way, which is not the default anymore since jQuery 3.0.

$.ajax({
    url: "/main/sub",
    data: data,
    traditional: true
})
