想了解C#遍历文件夹及其子目录的完整实现方法的相关内容吗,Eversnow在本文为您仔细讲解C#遍历文件夹及其子目录的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:C#,遍历,文件夹,子目录,下面大家一起来学习吧。

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<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>
    /// 遍历当前目录及子目录
    /// </summary>
    /// <param name="strPath">文件路径</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;
    }
  }
}

希望本文所述对大家C#程序设计有所帮助。
