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;
}
}
}
