Answer 1

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;namespace ConsoleApplication2
{
class Program
{

static void Main(string[] args)
{
string pathnames = null;
do
{
Console.Write("\n请输入目录路径名(输入x退出程序):");
pathnames = Console.ReadLine();
if ((pathnames == "X") || (pathnames == "x"))
break;
DirectoryInfo di = new DirectoryInfo(pathnames);
if (di == null)
{
return;
}
FileSystemInfo[] fs = di.GetFileSystemInfos();
foreach (FileSystemInfo f2 in fs)
{
FileInfo file = f2 as FileInfo;
if (file != null)
{
Console.Write("\n"+file.Name);
}
else
{
CFileList FileListTest = new CFileList();
FileListTest.FileList(f2);
}
}
} while (true);
Console.Write("\n程序已终止，按任意键退出程序!");
Console.ReadKey();
}
}////
class CFileList
{
public void FileList(FileSystemInfo f)//FileList为自己创建的方法
{
if (!f.Exists)//先判断f所指的文件或文件夹是否存在
{
return;
}
DirectoryInfo di = f as DirectoryInfo;
if (di == null)
{
return;
}
FileSystemInfo[] fs = di.GetFileSystemInfos();//获取文件夹中所有文件和文件夹
//下而对单个FileSystemInfo进行判断,如果是文件夹则进行递归操作
foreach (FileSystemInfo f2 in fs)
{
FileInfo file = f2 as FileInfo;
if (file != null)
{
Console.Write("\n"+file.Name);//如果是文件则将文件名加入到listBox1
}
else
{
FileList(f2);
}
} } }

返回List<string>（与字符串数组一样）private List<string> GetFileListUnderDirectory(string strDirectory)
{
List<string> strFileList = new List<string>(); if (Directory.Exists(strDirectory))
{
DirectoryInfo directoryInfo = new DirectoryInfo(strDirectory);
FileInfo[] fileInfo = directoryInfo.GetFiles(); foreach (FileInfo info in fileInfo)
{
strFileList.Add(info.Name);
}
}
else
{
strFileList.Add("No file under this directory!");
} return strFileList;
}
