在此实例中需要先将System.IO空间引入，然后在VS编辑器中输入以下代码，且以ListDrivers.aspx保存。

using System;

using System.Collections;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Web;

using System.Web.SessionState;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.HtmlControls;

using System.IO;

namespace PracticeProject.Practice1

{

/// <summary>

/// ListDrives 的摘要说明。

/// </summary>

public class ListDrivers : System.Web.UI.Page

{

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

{

if (!IsPostBack)

{

BindDrivers();

}

private void BindDrivers()

{

string[] achDrivers = Directory.GetLogicalDrives();

int nNumOfDrivers = achDrivers.Length;

Response.Write("<ul>");

for (int i = 0;i < nNumOfDrivers; i++)

{

Response.Write("<li><a href='ListDir.aspx?dir=");

Response.Write(Server.UrlEncode(achDrivers[i]));

Response.Write("' target='_blank'>" + achDrivers[i]);

Response.Write("</a><br>");

}

Response.Write("</ul>");

}
