递归生成treeView有关问题

递归生成treeView问题
有一个递归，教我一下怎么写，我有一个表，现在要建一个treeNode，现在要自动生成，表里有两字段，一个是id 一个是nodeID，只要某条数据nodeID等于某条数据id那么，这个数据是那个数据的子节点，我知道应该要递归算法，现在没有头绪

[解决办法]

C# code

private void InitTree(TreeNodeCollection Nds,int parentid)        {            DataView dv = new DataView();            TreeNode tmpNd = null;            dv.Table = ds.Tables[0];            dv.RowFilter = String.Format("parentid={0}", parentid);            foreach (DataRowView drv in dv)            {                tmpNd = new TreeNode();                tmpNd.Text = (string)drv["sortname"];//节点名称                tmpNd.NavigateUrl = String.Format("?id={0}", drv["id"]);//节点URL                //tmpNd.ImageUrl = ""; //节点图片                if (parentid == 0)                    tmpNd.Expanded = true;                else                    tmpNd.Expanded = false;                Nds.Add(tmpNd);                InitTree(Nds[Nds.Count - 1].ChildNodes, (int)drv["id"]);            }        }
