获取子目录利用的是 DirectoryInfo 的 GetDirectories() 和 GetFiles() 方法，这两个方法分别返回 FileInfo 数组和 DirectoryInfo 数组。名称空间为 System.IO。
<%@ Page Language="C#" %>
<%@ Import Namespace="System.IO" %>
<script runat="server">
void Page_Load(object sender, EventArgs e)
{
DirectoryInfo di = new DirectoryInfo("E:\\WebPages\\test");
//列出子目录
DirectoryInfo[] subDirs = di.GetDirectories();
for (int i=0; i<subDirs.Length; i++)
{
fileList.Text += "[" + subDirs[i].Name + "]" + "<br>";
}
//列出文件
FileInfo[] files = di.GetFiles();
for (int i = 0; i < files.Length; i++)
{
fileList.Text += files[i].Name + "<br>";
}
}
</script>
