<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>&nbsp;protected void Page_Load(object sender, EventArgs e)<BR>&nbsp;&nbsp;&nbsp; {<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (!IsPostBack)<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ShowFolderSchema();<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<BR>&nbsp;&nbsp;&nbsp; }</P> <P>&nbsp;&nbsp;&nbsp; private void ShowFolderSchema()<BR>&nbsp;&nbsp;&nbsp; {<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; string LocalFolderPath = Server.MapPath("");<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (LocalFolderPath != string.Empty)<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; this.treeView1.Nodes.Clear();<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; TreeNode[] tn = LoadDirectoryInfo(LocalFolderPath);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; foreach( TreeNode tvn in tn)<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {</P> <P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; tvn.Value = Server.MapPath(tvn.Text);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; this.treeView1.Nodes.Add(tvn);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<BR>&nbsp;&nbsp;&nbsp; }</P> <P>&nbsp;&nbsp;&nbsp; internal TreeNode[] LoadDirectoryInfo(string folderPath)<BR>&nbsp;&nbsp;&nbsp; {<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; DirectoryInfo di = new DirectoryInfo(folderPath);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; DirectoryInfo[] dis = di.GetDirectories();<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; TreeNode[] tn = new TreeNode[dis.Length];<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for (int i = 0; i &lt; dis.Length; i++)<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; tn[i] = new TreeNode(dis[i].Name);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; tn[i].Value = Server.MapPath(dis[i].ToString());<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TreeNode[] TempTn = LoadDirectoryInfo(dis[i].FullName);</P> <P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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。

http://www.codeproject.com/KB/tree/TreeViewWalker.aspx 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】
