下面是asp.net获取文件夹下的所有文件的代码：

using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;

public partial class admin_Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string path = Server.MapPath("/ceshi/");
DirectoryInfo di = new DirectoryInfo(path);
//找到该目录下的文件
FileInfo[] fis = di.GetFiles();
foreach (FileInfo fi in fis)
{
Response.Write(fi.Name);
Response.Write("<br>");
}
}
}
