如何递归遍历某个文件夹中的所有文件?

Question

遍历某个文件夹中的所有文件(包含任意层子目录), 对每个文件实施一种变换操作

Answer 1

这个是控制台程序  将文件夹的目录按层次打印的    class Program
    {
        static int i = 0;
        static void Main(string[] args)
        {
            string strPath = Console.ReadLine();
            DirectoryInfo di = new DirectoryInfo(strPath); 
            Console.WriteLine(di.Name);
            OutPutFiles(di);               Console.ReadLine();
        }        /// <summary>
        /// 打印输入路径中的所有子文件和子文件夹
        /// </summary>
        /// <param name="di">要显示的路径</param>
        static void OutPutFiles(DirectoryInfo di)
        {
            try
            {
                foreach (FileSystemInfo fsi in di.GetFileSystemInfos())
                {
                    
                    i++;
                    OutputSpace(i);
                    Console.WriteLine(fsi.Name);
                    if ((fsi as DirectoryInfo)!=null)
                    {
                        OutPutFiles((DirectoryInfo)fsi);
                    }
                    i--;
                }
            }
            catch {}            //无权访问的文件夹直接跳过
        }        /// <summary>
        /// 打印阶梯空格以显示文件等级
        /// </summary>
        /// <param name="i">等级标识</param>
        static void OutputSpace(int i)
        {
            for (int j = 0; j < i; j++)
            {
                Console.Write("    ");
            }
        }
    }

Answer 2

string Path = "C:"; 
string[] dir=Directory.GetDirectories(Path);//获取C:下所有文件夹 
string[] files = Directory.GetFiles(Path);//获取C:下所有文件 递归调用这两个方法

Answer 3

可以参考我这里写的代码：
/// <summary>
/// 路径分割符
/// </summary>
private const string PATH_SPLIT_CHAR = "\\";/// <summary>
         /// 将指定目录下的子目录和文件生成xml文档
         /// </summary>
         /// <param name="targetDir">根目录</param>
         /// <returns>返回XmlDocument对象</returns>
         public static XmlDocument CreateXml(string targetDir)
         {
              XmlDocument myDocument = new XmlDocument();
              XmlDeclaration declaration = myDocument.CreateXmlDeclaration("1.0","utf-8",null);
              myDocument.AppendChild(declaration);
              XmlElement rootElement = myDocument.CreateElement(targetDir.Substring(targetDir.LastIndexOf(PATH_SPLIT_CHAR) + 1));
              myDocument.AppendChild(rootElement);
              foreach(string fileName in Directory.GetFiles(targetDir))
              {
                   XmlElement childElement = myDocument.CreateElement("File");  
                   childElement.InnerText = fileName.Substring(fileName.LastIndexOf(PATH_SPLIT_CHAR) + 1); 
                   rootElement.AppendChild(childElement);
              }
              foreach(string directory in  Directory.GetDirectories(targetDir))
              {
                   XmlElement childElement = myDocument.CreateElement("Directory");
                   childElement.SetAttribute("Name",directory.Substring(directory.LastIndexOf(PATH_SPLIT_CHAR) + 1));
                   rootElement.AppendChild(childElement);
                   CreateBranch(directory,childElement,myDocument);
              }
              return myDocument;
         }         /// <summary>
         /// 生成Xml分支
         /// </summary>
         /// <param name="targetDir">子目录</param>
         /// <param name="xmlNode">父目录XmlDocument</param>
         /// <param name="myDocument">XmlDocument对象</param>
         private static void CreateBranch(string targetDir,XmlElement xmlNode,XmlDocument myDocument)
         {
              foreach(string fileName in Directory.GetFiles(targetDir))
              { 
                   XmlElement childElement = myDocument.CreateElement("File"); 
                   childElement.InnerText = fileName.Substring(fileName.LastIndexOf(PATH_SPLIT_CHAR)+1); 
                   xmlNode.AppendChild(childElement);
              }
              foreach(string directory in  Directory.GetDirectories(targetDir))
              {
                   XmlElement childElement = myDocument.CreateElement("Directory"); 
                   childElement.SetAttribute("Name",directory.Substring(directory.LastIndexOf(PATH_SPLIT_CHAR) + 1));
                   xmlNode.AppendChild(childElement);
                   CreateBranch(directory,childElement,myDocument);
              }
         } 

Answer 4

string[] dir=Directory.GetDirectories(Path);//获取Path下所有文件夹 
string[] files = Directory.GetFiles(Path);//获取Path下所有文件 递归的来做

Answer 5

string[] files = Directory.GetFiles(folder);查看MSDN，或Google搜一下相关内容，看看就能明白
