<P>我在treeview中用递归方法生成了一个目录树,但我想从中得到选择的目录的物理路径!<BR>代码如下:请各位大侠指点迷津<BR> protected void Page_Load(object sender, EventArgs e)<BR> {<BR> if (!IsPostBack)<BR> {<BR> ShowFolderSchema();<BR> }<BR> }</P>
<P> private void ShowFolderSchema()<BR> {<BR> string LocalFolderPath = Server.MapPath("");<BR> <BR> if (LocalFolderPath != string.Empty)<BR> {<BR> this.treeView1.Nodes.Clear();<BR> TreeNode[] tn = LoadDirectoryInfo(LocalFolderPath);<BR> foreach( TreeNode tvn in tn)<BR> {</P>
<P> tvn.Value = Server.MapPath(tvn.Text);<BR> this.treeView1.Nodes.Add(tvn);<BR> }<BR> }<BR> }</P>
<P> internal TreeNode[] LoadDirectoryInfo(string folderPath)<BR> {<BR> DirectoryInfo di = new DirectoryInfo(folderPath);<BR> DirectoryInfo[] dis = di.GetDirectories();<BR> TreeNode[] tn = new TreeNode[dis.Length];<BR> for (int i = 0; i < dis.Length; i++)<BR> {<BR> <BR> <BR> tn[i] = new TreeNode(dis[i].Name);<BR> tn[i].Value = Server.MapPath(dis[i].ToString());<BR> TreeNode[] TempTn = LoadDirectoryInfo(dis[i].FullName);</P>
<P> foreach(TreeNode tvn in TempTn)<BR>&am

不是有这一句吗：tn[i].Value = Server.MapPath(dis[i].ToString());
你可以用treeView1.SelectedValue或者treeView1.SelectedNode.Value来获取选择的节点对应的路径。

去看看这篇文章吧，从遍历文件夹到定位节点都用了，取全路径更是信手拈来啦
这句就可以了：this.label1.Text = this.treeAdvanced.SelectedNode.FullPath;【WebForm是SelectedNode.ValuePath】
