大家好，我在asp.net 中的treeview 控件有问题。我想用 xml 文件填充它，但 asp.net 中的树视图与窗口窗体树视图控件不同：/

我的树视图的名称是树视图...我在文件夹中没有 xml 我创建了一个 xml 字符串并使用它，但在此示例中我只想测试如何用代码填充此树视图。我怎么能用我的方法做到这一点？

这是我的代码：

XElement doc = XElement.Load("~/App_Data/test_xml.xml");

            TreeNode Feature;
            TreeNode User;
            foreach (XElement state in doc.Descendants("FEATURE"))
            {
                Feature = treeview.Nodes.Add(state.Attribute("NAME").Value);
                foreach (XElement region in state.Descendants("USER"))
                {
                    User =
                        Feature.Nodes.Add(region.Attribute("NAME").Value);
                    foreach (XElement area in region.Descendants("NAME"))
                    {
                        User.Nodes.Add(area.Attribute("NAME").Value);
                    }
                }
            }

您可以XmlDataSource 按照 Jeremy 的建议使用或更改代码，如下所示

XElement doc = XElement.Load("~/App_Data/test_xml.xml");
TreeNode root = new TreeNode("FEATURES");
foreach (XElement state in doc.Descendants("FEATURE"))
{
    TreeNode feature = new TreeNode(state.Attribute("NAME").Value);
    foreach (XElement region in state.Descendants("USER"))
    {
        TreeNode user =  new TreeNode(region.Attribute("NAME").Value);
        foreach (XElement area in region.Descendants("NAME"))
        {
            user.ChildNodes.Add(new TreeNode(area.Attribute("NAME").Value));
        }
        feature.ChildNodes.Add(user);
    }
    root.ChildNodes.Add(feature);
}
treeview.Nodes.Add(root);
