C#遍历文件夹及其子目录的完整实现方法

本文实例讲述了C#遍历文件夹及其子目录的完整实现方法。分享给大家供大家参考，具体如下：

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("\"))
      {
 str += "\";
      }
      IList 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("rn");
 }
 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 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;
 }
      }
    }
    /// 

    /// 遍历当前目录及子目录
    /// 
    /// 文件路径
    /// 所有文件
    private static IList GetFiles(string strPath)
    {
      List lstFiles = new List();
      List lstDirect = new List();
      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;
    }
  }
}
