在为listview绑定图标时先调用ListViewSysImages（）方法，让后 items.ImageIndex = GetFileImageIcon（文件路径）;
那么如何为treeview绑定呢？？？node.ImageIndex (文件路径)，没有显示图标。现在搞不懂ListViewSysImages（）方法。请大神们帮忙解决？？？？
如果将获得的图标添加到自定义的ImageList类中，让treeview的ImageList与自定义的绑定，获得到的图标不完全。所以不想用此方法。
网上查阅说treeview可以绑定系统的ImageList，所以我感觉ListViewSysImages（）方法应该是绑定系统的ImageList，可是不知道该如何修改。

为TreeView添加图片 private void btn_Get_Click(object sender, EventArgs e) { treeView1.ImageList = imageList1;//绑定ImageList控件 TreeNode tr = new TreeNode("公司职员", 0, 1); tr.Nodes.Add("", "张大力", 0, 1); tr.Nodes.Add("", "王小健", 0, 1); tr.Nodes.Add("", "李明丽", 0, 1); tr.Nodes.Add("", "刘雅洁", 0, 1); tr.Nodes.Add("", "孰小康", 0, 1); tr.Nodes.Add("", "赵名企", 0, 1); tr.Nodes.Add("", "懂佳音", 0, 1); tr.Nodes.Add("", "高小凡", 0, 1); treeView1.Nodes.Add(tr); treeView1.ExpandAll(); }
