可以根据XML恢复目录至指定地点创建的文件为空
xml如下

<?xml version="1.0" encoding="utf-8"?><directory_root directory_fullname="C:\Users\nhuang\Documents\学习资料">    <folder name="图书资料" directory_modify_time="2016/8/17 8:13:22">        <file name="C#高级编程(第7版).pdf" file_modify_time="2011/11/6 18:45:28">70b7d7f2d61ddaa4019ce9b89cbd4eb6</file>        <file name="CLR via C#  第4版.pdf" file_modify_time="2016/8/15 17:24:00">b893e5a6d0196472a97a5d131c36546b</file>    </folder>    <folder name="视频资料" directory_modify_time="2016/8/18 13:15:21">        <folder name="New folder" directory_modify_time="2016/8/18 13:15:29">            <file name="New Text Document.txt" file_modify_time="2016/8/18 15:01:15">no access</file>        </folder>        <file name="IT行为规范.wmv" file_modify_time="2016/8/15 16:24:46">f6b7bd84ee5cb046efc84e1ede45292c</file>        <file name="邮件书写规范.wmv" file_modify_time="2016/8/16 10:15:06">bab1502343ac95f1ecfe9b95d13889c0</file>    </folder>    <file name="c#中级培训 WFC.pptx" file_modify_time="2016/8/18 10:59:32">d41d8cd98f00b204e9800998ecf8427e</file>    <file name="c#中级培训 异常处理.pptx" file_modify_time="2016/8/18 10:59:32">d41d8cd98f00b204e9800998ecf8427e</file>    <file name="c#初级培训 IO与XML.pptx" file_modify_time="2016/8/18 10:59:32">d41d8cd98f00b204e9800998ecf8427e</file>    <file name="c#初级培训 数据库编程.pptx" file_modify_time="2016/8/18 10:59:32">d41d8cd98f00b204e9800998ecf8427e</file></directory_root>

c#函数

public static void RestoreAllFilesFormXML(string RestoreFilePath, string sourceXmlFilePath, XmlDocument xmlDoc, XmlNode rootNode)    {            string fullName = null;//XML存储的信息的位置            string rootName = null;            if(rootNode == null)            {                xmlDoc = new XmlDocument();                xmlDoc.Load(sourceXmlFilePath);                rootNode = xmlDoc.SelectSingleNode(@"/directory_root");                        fullName = rootNode.Attributes["directory_fullname"].Value;                Console.WriteLine("FullName: " + fullName);                DirectoryInfo rootDirectory = new DirectoryInfo(fullName);                rootName = rootDirectory.Name;//得到该文件夹的名字                Console.WriteLine("RootName: " + rootName);                DirectoryInfo restoreDirectory = new DirectoryInfo(RestoreFilePath);                restoreDirectory.CreateSubdirectory(rootName);//创建根目录                RestoreFilePath = RestoreFilePath +"\\"+ rootName;            }            else            {                fullName = RestoreFilePath;                DirectoryInfo rootDirectory = new DirectoryInfo(fullName);                rootName = rootDirectory.Name;//得到该文件夹的名字                Console.WriteLine("FullName2: " + fullName);            }            XmlNodeList subFolder = rootNode.SelectNodes("folder");//XML中子文件夹集合            foreach(XmlNode node in subFolder)            {                string subFolderbName = node.Attributes["name"].Value;                Console.WriteLine("subFolderbName: " + subFolderbName);                DirectoryInfo subRestoreDirectory = new DirectoryInfo(RestoreFilePath);                subRestoreDirectory.CreateSubdirectory(subFolderbName);//创建文件夹                string subRestorePath = RestoreFilePath  + "\\"  + subFolderbName;                Console.WriteLine("subRestorePath: " + RestoreFilePath + "\\"  + subFolderbName);                RestoreAllFilesFormXML(subRestorePath, sourceXmlFilePath, xmlDoc, node);//递归 恢复该文件夹下的文件            }            XmlNodeList subFile = rootNode.SelectNodes("file");//XML中子文件集合            foreach (XmlNode node in subFile)            {                string fileName = node.Attributes["name"].Value;                Console.WriteLine("subFileName: " + fileName);                Console.WriteLine(RestoreFilePath + "\\" + rootName + "\\" + fileName);                File.Create(RestoreFilePath + "\\" + "\\" + fileName);//创建文件            }        }

main函数调用

public static string LogPath = @"C:\Users\nhuang\Desktop\mylog.txt";public static string DirectoryPath = @"C:\Users\nhuang\Documents\学习资料";public static string DestinationXMLPath = @"C:\Users\nhuang\Desktop\a.xml";public static string RestoreFilePath = @"C:\Users\nhuang\Desktop";internal static void Main()        {            try            {                XmlNode tempNode = null;                XmlDocument xmlDoc = new XmlDocument();                RestoreAllFilesFormXML(RestoreFilePath, DestinationXMLPath, xmlDoc, tempNode);            }            catch (InvalidOperationException)            {                // 异常处理程序            }            catch (IOException ex)            {                MyLog(LogPath, "Error   " + System.DateTime.Now.ToLongTimeString() + " :" + ex.Message);//ErrorLog            }            catch            {                throw;            }            finally            {            }        }
