将指定文件夹下的文件遍历到treeview中的问题 急，急，高手帮忙！！

[dew_you]

public partial class Form1 : Form
   {
        public Form1()
        {
            InitializeComponent();
        }
        TreeView treeView1 = new TreeView();
        TreeNode selnode = new TreeNode();
        TreeNode selnodeNext = new TreeNode();
        TreeNode User = new TreeNode();
        TreeNode test = new TreeNode();
        TreeNode notes = new TreeNode();
        string rootPath = "c:\\diyou";
        string currentPath = "";
        string name="diyou";
        private void Form1_Load(object sender, EventArgs e)
        {

            createTreeView();
            DirectoryInfo dir = new DirectoryInfo(@rootPath);
            User = new TreeNode(name);//根节点
            show(dir);
            treeView1.Nodes.Add(User);
            Controls.Add(treeView1);
        }
        private void createTreeView()
        {
            treeView1 = new TreeView();
            treeView1.Size = new Size(100, 200);
            treeView1.Dock = DockStyle.Left;
        }
        private void show(DirectoryInfo dir)//这个函数应该怎么写？？
        {
            foreach (DirectoryInfo dirX in dir.GetDirectories())
            {
                selnode = new TreeNode(dirX.Name);//文件夹节点
                foreach (FileInfo File in dir.GetFiles())
                {
                    selnodeNext = new TreeNode(File.Name);//文件节点   
                    selnode.Nodes.Add(selnodeNext);//文件节点加到selnode之下
                    User.Nodes.Add(selnode);//selnode节点加到User根节点下
                    show(dirX);
                }
            }
        }
}

怎么解决这个问题，使文件夹和文件按资源管理器一样分级表示？？

[hhc123]

动态遍历比较好吧

怎么动态遍历？？

[wuyq11]

递归遍历文件夹添加结点
private static void getDirectories(string path,TreeNode tn)
{
string[] fileNames = Directory.GetFiles(path);
string[] directories = Directory.GetDirectories(path);
foreach (string dir in directories)
{
TreeNode node= new TreeNode();
node.Text = GetShorterFileName(dir);
node.ImageUrl = "~/Images/open.gif";
node.Expanded = false;
node.NavigateUrl = "#";
getDirectories(dir,node);
tn.ChildNodes.Add(node);

}
foreach (string file in fileNames)

{
TreeNode node= new TreeNode();
node.ImageUrl = "~/Images/file.gif";
node.Text = GetShorterFileName(file);
tn.ChildNodes.Add(node);
}
}
