DynaTree返回List的问题

[kingsavage]

我做了一个List<>的Tree结构，返回是这样的：
List<myTreeNode> dyTree = Tdata.GetDyTreeMList();
object obj = new { Success = true, Message = "OK", List = dyTree };
return Json(obj, JsonRequestBehavior.AllowGet);

页面上：

 <script type="text/javascript">
            alert("QQ");
            $(document).ready(function () {
                // Attach the dynatree widget to an existing <div id="tree"> element   
                // and pass the tree options as an argument to the dynatree() function:   
                $("#tree").dynatree({
                    initAjax: {
                        type: "POST",
                        dataType: "json",
                        url: "/myTs/GetJsTreeList",
                        data: { id: 10 },
                        error: function (exp) {
                            alert('Error : ' + exp.responseText);
                        }
                    },

                onActivate: function (node) {
                    alert("You activated " + node.data.icon);
                }
            });
        });
        </script>

并没有返回树的列表。
想问下，List<>返回怎么处理显示结构啊?
我用JsTree试过List<>返回，
在 success: function (data) {
return data.List
}
就可以了，但dynaTree不知道怎么做。

public class TreeNodes
    {
        /// <summary>
        /// 构造函数
        /// </summary>
        /// <param name="t">title：节点显示的名称</param>
        /// <param name="k">key：节点的值</param>
        /// <param name="cb">是否显示checkbox</param>
        /// <param name="isDel">是否允许删除</param>
        public TreeNodes(string t, string k, bool cb, bool isDel)
        {
            children = new List<TreeNodes>();
            expand = true;
            isFolder = true;
            title = t;
            key = k;
            hideCheckbox = cb;
            isCanBeDel = isDel;
            keyboard = true;
            focus = false;
        }

        public string title { get; set; }
        public string key { get; set; }
        public bool expand { get; set; }
        public bool isFolder { get; set; }
        public bool hideCheckbox { get; set; }
        public bool isCanBeDel { get; set; }
        public List<TreeNodes> children { get; set; }
        public bool keyboard { get; set; }
        public bool focus { get; set; }
    }

定义treenodes节点 递归数据填充treenodes 返回数据：

context.Response.Write(JavaScriptHelper.JsonSerializer.Serialize(nodes));

dyTree 是需要一些固定的属性名称的，不是你从数据库查的什么列名就往里面填充什么，它识别不了

前端：

function GetDynaTreeSource() {
    $.ajax({
        url: /Photo/Photo.ashx?type=getdynatreesource&t=" + (new Date()).valueOf(),
        dataType: "json",
        type: "post",
        timeour: 6000,
        success: function(data) {
            if (data) {
                InitDynaTree(data);
                            }
        },
        error: function (e, x) {
                        
        }
    });
}
function InitDynaTree(data) {
    $("#myTree").dynatree({
        persist: true,
        checkbox: false,
        selectMode: 3,
        children: data,
        onActivate: function(node) {
            
        },
    });

}
