这个应该要自己写代码绑定，写一个递归函数就可以了。
给个参考的吧



        public struct NodeInfo

        {

            public Guid gid;

            public string strNode;

            public Guid pid;

        }

PageLoad() OR FromLoad()

{

            NodeInfo[] NodeArr = new NodeInfo[5];

            NodeArr[0].gid = Guid.NewGuid();

            NodeArr[0].pid = Guid.Empty;

            NodeArr[0].strNode = "信息部";



            NodeArr[1].gid = Guid.NewGuid();

            NodeArr[1].pid = NodeArr[0].gid;

            NodeArr[1].strNode = "小红";



            NodeArr[2].gid = Guid.NewGuid();

            NodeArr[2].pid = NodeArr[0].gid;

            NodeArr[2].strNode = "小张";



            NodeArr[3].gid = Guid.NewGuid();

            NodeArr[3].pid = Guid.Empty;

            NodeArr[3].strNode = "文化部";



            NodeArr[4].gid = Guid.NewGuid();

            NodeArr[4].pid = NodeArr[3].gid;

            NodeArr[4].strNode = "小莉";



            BD(Guid.Empty,treeView1.Nodes);

            treeView1.ExpandAll();

}



        private void BD(Guid pid,TreeNodeCollection cuNode)

        {

            //绑定数据

            foreach (NodeInfo cuInfo in NodeArr)

            {

                if (cuInfo.pid == pid)

                {

                    TreeNode PNode = new TreeNode(cuInfo.strNode);

                    cuNode.Add(PNode);

                    BD(cuInfo.gid,PNode.Nodes);

                }

            }

        }
