调用实例：
protected Microsoft.Web.UI.WebControls.TreeView tvMenu;
。。。。。
DataView myDv = MenuData.GetMenuData();
   MenuData.CreateMenuTree(myDv,tvMenu.Nodes,"0");


private void getAllCheckedNode( Microsoft.Web.UI.WebControls.TreeNodeCollection tnc)
{
         node = Microsoft.Web.UI.WebControls.TreeNode
        foreach(Microsoft.Web.UI.WebControls.TreeNode node in tnc)
 {
            if (node.Nodes.Count != 0 )
                getAllCheckedNode(node.Nodes);
            if (node.Checked )
                insertIntoDs(node.Text, node.NodeData);
        }
 }
