这个函数比较重要，递归获得指定目录下的所有文件信息，当然包括里面的子文件信息
/// <summary>
/// 返回指定目录下的所有文件信息
/// </summary>
/// <param name="strDirectory"></param>
/// <returns></returns>
public void GetAllFilesInDirectory(string strDirectory)
{

DirectoryInfo[] directoryArray = directory.GetDirectories();
FileInfo[] fileInfoArray = directory.GetFiles();
if (fileInfoArray.Length > 0) listFiles.AddRange(fileInfoArray);
foreach (DirectoryInfo _directoryInfo in directoryArray)
{
GetAllFilesInDirectory(_directoryInfo.FullName);//递归遍历
}
}

}
这是一小段拼接HTML内容的代码...- -！看不懂的就问
GetAllFilesInDirectory(HttpContext.Current.Server.MapPath(dateStr));
_showStr.Append("<table border='1'>");
_showStr.Append("<tr><td>文件名</td><td>文件大小</td><td>创建时间</td><td>文件目录</td></tr>");
for(int i = ; i<listFiles.Count; i++)
{
string herf = listFiles[i].FullName.Substring(_urlStr.Length, listFiles[i].FullName.Length - _urlStr.Length);
herf = herf.Replace('\\', '/');
_showStr.Append("<tr><td><A HREF='" + herf + "'>" + listFiles[i].Name + "</A></td><td>" + listFiles[i].Length + "</td><td>" + listFiles[i].CreationTime + "</td><td>" + listFiles[i].FullName+ "</td></tr>");
}
_showStr.Append("</table>"); htmlStr = GetHtmlStr(_urlStr, _showStr.ToString()); Response.Write(htmlStr);
