前端Js传递数组至服务器端

 $("#delete").click(function () {
                var ID = "";
                var ary = [];
                var bb = document.getElementsByName("PersonId");
                $('input:checkbox[name="PersonId"]:checked').each(function () {
                    ary.push($(this).val());
                });
                if (ary.length == 0) {
                    alert("请选择至少一条");
                }
                else {
                    $.ajax({
                        type: "POST",
                        url: "@Url.Content("~/User/BatchDelete")",
                        contentType: "application/json;charset=utf-8",
                        dataType: "json",
                        data: JSON.stringify(ary),
                        success: function (data) {
                            var i = 0;
                            $('input:checkbox[name="PersonId"]:checked').each(function () {
                                window.location.reload();
                            });
                        }
                    });
                }
            });

服务器端（asp.net mvc controller）

       [HttpPost]
        public async Task<ActionResult> BatchDelete(string[] ary)
        {
            foreach (var id in ary)
            {

            }
            return Json(" ");
        }
