<script type="text/javascript">
        $(function () {
            var obj = { name: "军需品", myclass: [{
                one: 1,
                two: 2,
                three: 3
            }, {
                one: 11,
                two: 22,
                three: 33
            }, {
                one: 111,
                two: 222,
                three: 333
            }]
            };

            $.ajax({
                url: '<%=Url.Content("~/Home/GetList") %>',
                type: 'POST',
                dataType: 'json',
                data: JSON.stringify(obj),
                contentType: 'application/json; charset=utf-8',
                success: function (data, state) {
                    alert(JSON.stringify(data));
                    alert(state);
                }
            });
        });
    </script>

public class HomeController : Controller
    {
        //
