本文實例講述了C#遍歷文件夾及其子目錄的完整實現方法。分享給大家供大家參考，具體如下：
using System;using System.Collections;using System.Collections.Generic;using System.IO;using System.Security.AccessControl;using System.Text;namespace ConsoleApplication1{ class Program { static void Main(string[] args) { Console.WriteLine("STT"); string str = @"E:/"; if (!str.EndsWith("http://")) { str += "http://"; } IList<FileInfo> lst = GetFiles(str); if (!Directory.Exists(str)) { try { Directory.CreateDirectory(str); } catch(Exception e) { Console.WriteLine(e.Message); Console.ReadKey(); return; } } if (File.Exists(str + "test.txt")) { File.Delete(str + "test.txt"); } FileInfo file = new FileInfo(str + "test.txt"); if (!file.Directory.Exists) { Directory.CreateDirectory(file.DirectoryName); } using (StreamWriter outFileWriter = new StreamWriter(str + "test.txt", false, Encoding.UTF8)) { StringBuilder sb = new StringBuilder(); foreach (FileInfo item in lst) { sb.Append("/""); sb.Append(item.FullName); sb.Append("/""); sb.Append(","); sb.Append("/r/n"); } sb.Remove(sb.Length - 2, 2); outFileWriter.WriteLine(sb.ToString()); outFileWriter.Flush(); outFileWriter.Close(); } Console.WriteLine("END"); Console.ReadKey(); } private static void GetDirectorys(string strPath, ref List<string> lstDirect) { DirectoryInfo diFliles = new DirectoryInfo(strPath); DirectoryInfo[] diArr = diFliles.GetDirectories(); //DirectorySecurity directorySecurity = null; foreach (DirectoryInfo di in diArr) { try { //directorySecurity = new DirectorySecurity(di.FullName, AccessControlSections.Access); //if (!directorySecurity.AreAccessRulesProtected) //{ lstDirect.Add(di.FullName); GetDirectorys(di.FullName, ref lstDirect); //} } catch { continue; } } } /// <summary> /// 遍歷當前目錄及子目錄 /// </summary> /// <param name="strPath">文件路徑</param> /// <returns>所有文件</returns> private static IList<FileInfo> GetFiles(string strPath) { List<FileInfo> lstFiles = new List<FileInfo>(); List<string> lstDirect = new List<string>(); lstDirect.Add(strPath); DirectoryInfo diFliles = null; GetDirectorys(strPath, ref lstDirect); foreach (string str in lstDirect) { try { diFliles = new DirectoryInfo(str); lstFiles.AddRange(diFliles.GetFiles()); } catch { continue; } } return lstFiles; } }}更多關于C#相關內容感興趣的讀者可查看本站專題：《C#遍歷算法與技巧總結》、《C#程序設計之線程使用技巧總結》、《C#操作Excel技巧總結》、《C#中XML文件操作技巧匯總》、《C#常見控件用法教程》、《WinForm控件用法總結》、《C#數據結構與算法教程》、《C#數組操作技巧總結》及《C#面向對象程序設計入門教程》
