我想列出包含在目录和目录的子目录中的所有文件和目录。 如果我选择C：\作为目录，该计划将让每一个文件和文件夹的硬盘驱动器，它必须对接入的每一个名字。
名单看起来像
fd\1.txt fd\2.txt fd\a\ fd\b\ fd\a\1.txt fd\a\2.txt fd\a\a\ fd\a\b\ fd\b\1.txt fd\b\2.txt fd\b\a fd\b\b fd\a\a\1.txt fd\a\a\a\ fd\a\b\1.txt fd\a\b\a fd\b\a\1.txt fd\b\a\a\ fd\b\b\1.txt fd\b\b\a
string[] allfiles = Directory.GetFiles("path/to/dir", "*.*", SearchOption.AllDirectories);
其中*.*是要匹配的模式文件
如果该目录还需要可以是这样的：
foreach (var file in allfiles){
FileInfo info = new FileInfo(file);
// Do something with the Folder or just add them to a list via nameoflist.add();
}
Directory.GetFileSystemEntries存在于.NET 4.0+和返回文件和目录。 说它像这样：
string[] entries = Directory.GetFileSystemEntries(path, "*", SearchOption.AllDirectories);
请注意，它不会尝试列出您没有访问权限（UnauthorizedAccessException）子目录的内容应付，但它可能足以满足您的需求。
使用GetDirectories和GetFiles方法来获取文件夹和文件。
使用SearchOption AllDirectories得到的文件夹和文件的子文件夹也。
public static void DirectorySearch(string dir)
{
try
{
foreach (string f in Directory.GetFiles(dir))
{
Console.WriteLine(Path.GetFileName(f));
}
foreach (string d in Directory.GetDirectories(dir))
{
Console.WriteLine(Path.GetFileName(d));
DirectorySearch(d);
}
}
catch (System.Exception ex)
{
Console.WriteLine(ex.Message);
}
}
我很害怕，在GetFiles文件的方法返回列表中，但不是目录。 在问题清单提示我，结果应该包括文件夹以及。 如果您想了解更多自定义列表，您可以尝试调用GetFiles和GetDirectories递归。 试试这个：
List<string> AllFiles = new List<string>();
void ParsePath(string path)
{
string[] SubDirs = Directory.GetDirectories(path);
AllFiles.AddRange(SubDirs);
AllFiles.AddRange(Directory.GetFiles(path));
foreach (string subdir in SubDirs)
ParsePath(subdir);
}
提示：您可以使用FileInfo和DirectoryInfo ，如果你需要检查任何特定属性的类。
你可以使用它用FindFirstFile返回一个句柄，然后递归CAL这就要求FindNextFile.This是一个很好的形式给出的参考将充满各种数据，例如alternativeName，lastTmeCreated，改进结构的功能，属性等
但是当你使用.NET框架，你就必须进入非托管区域。
如果您没有访问该目录树中的子文件夹，Directory.GetFiles停止并抛出导致接收的String []在一个空值异常。
在这里，看到这个答案https://stackoverflow.com/a/38959208/6310707
它管理循环内的异常，并继续工作，直到整个文件夹遍历。
逻辑和有序的方式：
using System;
using System.Collections.Generic;
using System.IO;
using System.Reflection;
namespace DirLister
{
class Program
{
public static void Main(string[] args)
{
//with reflection I get the directory from where this program is running, thus listing all files from there and all subdirectories
string[] st = FindFileDir(Path.GetDirectoryName(Assembly.GetEntryAssembly().Location));
using ( StreamWriter sw = new StreamWriter("listing.txt", false ) )
{
foreach(string s in st)
{
//I write what I found in a text file
sw.WriteLine(s);
}
}
}
private static string[] FindFileDir(string beginpath)
{
List<string> findlist = new List<string>();
/* I begin a recursion, following the order:
* - Insert all the files in the current directory with the recursion
* - Insert all subdirectories in the list and rebegin the recursion from there until the end
*/
RecurseFind( beginpath, findlist );
return findlist.ToArray();
}
private static void RecurseFind( string path, List<string> list )
{
string[] fl = Directory.GetFiles(path);
string[] dl = Directory.GetDirectories(path);
if ( fl.Length>0 || dl.Length>0 )
{
//I begin with the files, and store all of them in the list
foreach(string s in fl)
list.Add(s);
//I then add the directory and recurse that directory, the process will repeat until there are no more files and directories to recurse
foreach(string s in dl)
{
list.Add(s);
RecurseFind(s, list);
}
}
}
}
}
下面的例子最快的（不是并行）的方式列表文件和子文件夹的目录树处理异常。 这将是更快地使用利用SearchOption.AllDirectories枚举所有目录Directory.EnumerateDirectories，但如果击中UnauthorizedAccessException或PathTooLongException此方法将失败。
采用通用协议栈集合类型，这是一个后进先出（LIFO）栈，并且不使用递归。 从https://msdn.microsoft.com/en-us/library/bb513869.aspx ，让您枚举所有子目录和文件，并与那些异常有效地处理。
public class StackBasedIteration
{
static void Main(string[] args)
{
// Specify the starting folder on the command line, or in
// Visual Studio in the Project > Properties > Debug pane.
TraverseTree(args[0]);
Console.WriteLine("Press any key");
Console.ReadKey();
}
public static void TraverseTree(string root)
{
// Data structure to hold names of subfolders to be
// examined for files.
Stack<string> dirs = new Stack<string>(20);
if (!System.IO.Directory.Exists(root))
{
throw new ArgumentException();
}
dirs.Push(root);
while (dirs.Count > 0)
{
string currentDir = dirs.Pop();
string[] subDirs;
try
{
subDirs = System.IO.Directory.EnumerateDirectories(currentDir); //TopDirectoryOnly
}
// An UnauthorizedAccessException exception will be thrown if we do not have
// discovery permission on a folder or file. It may or may not be acceptable
// to ignore the exception and continue enumerating the remaining files and
// folders. It is also possible (but unlikely) that a DirectoryNotFound exception
// will be raised. This will happen if currentDir has been deleted by
// another application or thread after our call to Directory.Exists. The
// choice of which exceptions to catch depends entirely on the specific task
// you are intending to perform and also on how much you know with certainty
// about the systems on which this code will run.
catch (UnauthorizedAccessException e)
{
Console.WriteLine(e.Message);
continue;
}
catch (System.IO.DirectoryNotFoundException e)
{
Console.WriteLine(e.Message);
continue;
}
string[] files = null;
try
{
files = System.IO.Directory.EnumerateFiles(currentDir);
}
catch (UnauthorizedAccessException e)
{
Console.WriteLine(e.Message);
continue;
}
catch (System.IO.DirectoryNotFoundException e)
{
Console.WriteLine(e.Message);
continue;
}
// Perform the required action on each file here.
// Modify this block to perform your required task.
foreach (string file in files)
{
try
{
// Perform whatever action is required in your scenario.
System.IO.FileInfo fi = new System.IO.FileInfo(file);
Console.WriteLine("{0}: {1}, {2}", fi.Name, fi.Length, fi.CreationTime);
}
catch (System.IO.FileNotFoundException e)
{
// If file was deleted by a separate application
// or thread since the call to TraverseTree()
// then just continue.
Console.WriteLine(e.Message);
continue;
}
catch (UnauthorizedAccessException e)
{
Console.WriteLine(e.Message);
continue;
}
}
// Push the subdirectories onto the stack for traversal.
// This could also be done before handing the files.
foreach (string str in subDirs)
dirs.Push(str);
}
}
}

一个littlebit简单和缓慢，但工作！ 如果你不给一个文件路径basicly使用“fixPath”这仅仅是例子....你可以搜索正确的fileType你想要什么，我做了一个错误，当我选择的列表名称，因为“temporaryFileList是搜索到的文件列表所以随身携带上....和“errorList”是不言自明
static public void Search(string path, string fileType, List<string> temporaryFileList, List<string> errorList)
{
List<string> temporaryDirectories = new List<string>();
//string fix = @"C:\Users\" + Environment.UserName + @"\";
string fix = @"C:\";
string folders = "";
//Alap útvonal megadása
if (path.Length != 0)
{ folders = path; }
else { path = fix; }
int j = 0;
int equals = 0;
bool end = true;
do
{
equals = j;
int k = 0;
try
{
int foldersNumber =
Directory.GetDirectories(folders).Count();
int fileNumber = Directory.GetFiles(folders).Count();
if ((foldersNumber != 0 || fileNumber != 0) && equals == j)
{
for (int i = k; k <
Directory.GetDirectories(folders).Length;)
{
temporaryDirectories.Add(Directory.GetDirectories(folders)[k]);
k++;
}
if (temporaryDirectories.Count == j)
{
end = false;
break;
}
foreach (string files in Directory.GetFiles(folders))
{
if (files != string.Empty)
{
if (fileType.Length == 0)
{
temporaryDirectories.Add(files);
}
else
{
if (files.Contains(fileType))
{
temporaryDirectories.Add(files);
}
}
}
else
{
break;
}
}
}
equals++;
for (int i = j; i < temporaryDirectories.Count;)
{
folders = temporaryDirectories[i];
j++;
break;
}
}
catch (Exception ex)
{
errorList.Add(folders);
