Edit try this , create array and pass that to your controller

    var stringArray = new Array();
    stringArray[0] = "item1";
    stringArray[1] = "item2";
    stringArray[2] = "item3";
    var postData = { listkey: stringArray };

than you data will be , in you ajax call

   data: postData 


$.ajax({
        type: "POST",
        url: '@Url.Action("Search", "Result")',
        data: postData,
        success: function(data){
            alert(data.Result);
        },
        dataType: "json",
        traditional: true
    });

you can do like this ,

1. convert you list into json string like as below

you data will be data: '{ "listkey":' + JSON.stringify(list) + '}',

$.ajax({
                                url: '@Url.Action("Search", "Result")',
                                traditional: true,
                                 data: '{ "listkey":' + JSON.stringify(list) + '}',
                                dataType: "html",
                                type: 'POST',
                                success: function (data) {
                                    alert("success");
                                },
                                error: function () {
                                    alert("fail");
                                }
                            });

than try to see you are getting result you want or not

  [HttpPost]
        public ActionResult Result(List<string> listkey)
        {
            var n = listkey;
            return View();
        }
