TreeView绑定硬盘文件

有时候需要做一个像资源管理器一样的东西来查看服务器中的文件，怎么做呢，我写了一个

using System;

using System.Data;

using System.Configuration;

using System.Collections;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

using System.IO;

namespace WebApplication1

{

public partial class _Default : System.Web.UI.Page

{

private void Page_Load(object sender, System.EventArgs e)

{

if (!IsPostBack)

{

BdTreeView(AppDomain.CurrentDomain.BaseDirectory,TreeView1.Nodes);

}

}

public void BdTreeView(string dir, TreeNodeCollection tc)

{

DirectoryInfo di = new DirectoryInfo(dir);

DirectoryInfo[] sunDir = di.GetDirectories();

FileInfo[] ffi = di.GetFiles();

foreach (DirectoryInfo i in sunDir)

{

TreeNode tn = new TreeNode();

tn.Text = Path.GetFileName(i.FullName);

tc.Add(tn);

BdTreeView(i.FullName, tn.ChildNodes);

}

foreach (FileInfo j in ffi)

{

TreeNode fileNode = new TreeNode();

fileNode.Text = System.IO.Path.GetFileName(j.FullName);

tc.Add(fileNode);

}

}

}

}
