树形导航列表与菜单列表实现同步

public void BindTree()
        {     
            DataSet ds = new DataSet();
            SqlServerDAL.MenuTree MT=new SqlServerDAL.MenuTree();
            ds=MT.GetCategory();
            treeview_hr.ImageList = imgtreeview;
            for (int i = 0; i < ds.Tables[0].Rows.Count; i++)

                //顶部菜单
                ToolStripMenuItem item= new ToolStripMenuItem(ds.Tables[0].Rows[i]["name"].ToString().Trim());
                menuStrip_hr.Items.Add(item);

                //树形菜单
                DataSet Cds = MT.GetcData(int.Parse(ds.Tables[0].Rows[i]["cID"].ToString()));

                {

                    ChildNodes[j] = new TreeNode();
                    ChildNodes[j].Text = Cds.Tables[0].Rows[j]["title"].ToString().Trim ();
                    ChildNodes[j].Tag = Cds.Tables[0].Rows[j]["dataID"].ToString().Trim ();
                    ChildNodes[j].ImageIndex = 1;
                    //顶部二级菜单
               
                    ToolStripMenuItem childitem = new ToolStripMenuItem(Cds.Tables[0].Rows[j]["title"].ToString().Trim());

                TreeNode node = new TreeNode(ds.Tables[0].Rows[i]["name"].ToString().Trim (), ChildNodes);
               
                treeview_hr.Nodes.Add(node);

        }
        private void childitem_Click(object sender, EventArgs e)
        {

            HR.ModuleClass.MyModule mymodule = new HR.ModuleClass.MyModule();
            mymodule.Show_Form(((ToolStripMenuItem)sender).Text); 
        }

        private void frm_main_Load(object sender, EventArgs e)
        {

        }


        private void treeview_hr_AfterSelect(object sender, TreeViewEventArgs e)
        {
            TreeNode node = e.Node;
            if (node.Level == 1) //子节点
            {
                HR.ModuleClass.MyModule mymodule = new HR.ModuleClass.MyModule();
                mymodule.Show_Form(node.Text.Trim());

                treeview_hr.SelectedImageIndex = 1;

            }
            else
            {
                treeview_hr.SelectedImageIndex = 0;
            }

首先需要为窗体添加ImageList，然后把所有需要显示的图标加载其中。   
  然后用此去初始化treeview的ImageList属性
注意：ImageList也是个控件。从工具箱找到ImageList   拖到你的TreeView上   然后就可以设置了
