So I have a directory where a bunch of configuration files are stored, but now I also have several sub directories which also contain config files. I had a function for collecting all configuration files per station, but now it's only collecting files in the directory, not the sub folders. old code:
string MasterList = "ConfigsForStation1.txt";
string dirC = "..\\config\\Station1\\";
foreach (FileInfo fileC in dirC.GetFiles())
{
if(!System.IO.Path.GetExtension(fileC.FullName).EndsWith(".confg"))
{ WriteToList(fileC,MasterList);}
}
and now with this sub directory stuff implemented its more along these lines:
string MasterList = ...;
string dirC = ...;
//collect files in sub directories substations 1 & 2
foreach(DirectoryInfo Dx in dirC.GetDirectories())
{ foreach(FileInfo fileC in Dx.GetFiles())
{...}
}
//collect files in parent directory station 1
foreach(FileInfo fileC in dirC.GetFiles())
{...}
my question is: is there a cleaner way to collect files from all sub folders rather then nest a foreach inside of a foreach? and then do a third pass for the stuff in parent. It feels abit sloppy and I feel like theres some command like dirC.getAllsub() that will do so for me? just looking for hints and ideas to clean up the code.
There's Directory.EnumerateFiles() to which you can pass a parameter of SearchOption.AllDirectories which you can use to tell it to recurse the files for you automatically.
You should be able to do something like:
foreach (string filename in Directory.EnumerateFiles(dirC, "*.confg", SearchOption.AllDirectories))
... Do something with filename
Or if you need to process every file:
foreach (string filename in Directory.EnumerateFiles(dirC, "*", SearchOption.AllDirectories))
... Do something with filename
The GetFiles() method will return them all in one shot:
String dirC = "..\\config\\Station1\\";
DirectoryInfo di = new DirectoryInfo(dirC);
FileInfo[] fia = di.GetFiles("*.*", SearchOption.AllDirectories);
foreach (FileInfo fi in fia)
{
//do something with the file
}
You can replace the search pattern *.* with whatever fits the files you are looking for, such as *.cfg.
Use Directory.GetFiles() with SearchOption.AllDirectories. That will automatically recurse for you.
I wanted to write this as a comment but stackoverflow wasn't letting me.
Check out this question which provides many ways to do what you're asking.
use Directory.GetFiles:
var files = Directory.GetFiles("C:\\", "*", SearchOption.AllDirectories);

I am trying to insert the full directory path as well as the file and extension into the String Array but I am not getting it, any chance someone has a better way to do this.
I am using the nested for each because there is a list of Directories below the main directory "directoryInfo" that have the files I am looking for.
string[] moveLocalFiles;
List<String> localFiles = new List<String>();
DirectoryInfo directoryInfo = new DirectoryInfo(sourceFilePath);
try
{
foreach (DirectoryInfo i in directoryInfo.GetDirectories())
{
foreach(FileInfo f in i.GetFiles(".twb"))
{
localFiles.Add(f.ToString());
}
moveLocalFiles = localFiles.ToArray();
foreach (string filePath in moveLocalFiles)
{
//do something
}
}
catch (Exception ex)
{
throw ex;
}
As Dan says you're definitely missing a "*" in your filter, but more than that you should use the FullName property, like this:
localFiles.Add(f.FullName);
Also (but this could be a desired behavior) you're browsing only the first level of subdirectories of "sourceFilePath" (excluding that directory as well).
And also in the sample code there's a missing bracket just before the "catch" line (but I understand this is just a sample code that you pasted here and not your real program).
I hope this helps.
It looks like you're missing a * before .twb in the GetFiles call.
If you want to get the full path to each Directory and File you can either use your own method just altered slightly:
foreach (DirectoryInfo i in directoryInfo.GetDirectories())
{
foreach (FileInfo f in i.GetFiles("*.twb")) //The * is a wildcard search for anything
{
localFiles.Add(f.FullName); //FullName returns the full path
}
}
Or you can use the System.IO.Directory class like so:
foreach (string i in Directory.GetDirectories("path to directory"))
{
foreach (string f in Directory.GetFiles(i, "*.twb")) //The * is a wildcard search for anything
{
localFiles.Add(f);
}
}
this is my code below. I've already created a filter that searches for any all image file extensions but when my code runs the SearchOption.AllDirectories appears to be trying to open a particular path instead of searching all my directories.
Anyone help me on where I've gone wrong here?
string[] filters = { "*.jpg", "*.jpeg", "*.png", "*.gif", "*.bmp" };
var directory = new DirectoryInfo(lblText.Text);
var files = new List<FileInfo>();
foreach (var filter in filters)
{
var results = directory.GetFiles(filter, SearchOption.AllDirectories);
files.AddRange(results);
}
Thanks for any help! :)
I assume directory is a DirectoryInfo object and you're using this overload of GetFiles. Then a FileInfo[] is returned from the current directory matching the given search pattern and searching all subdirectories.
So the directory-path of the DirectoryInfo is the root directory.
For example:
DirectoryInfo imageDir = new DirectoryInfo(#"c:\Images");
FileInfo[] allJPGImages = imageDir.GetFiles(".jpg", SearchOption.AllDirectories);
Edit according to your edit.
So the particular path is the Text entered/shown in lblText. Another way to get all files with these extensions:
string[] filters = { "*.jpg", "*.jpeg", "*.png", "*.gif", "*.bmp" };
List<FileInfo> files = filters
.SelectMany(filter => directory.EnumerateFiles(filter, System.IO.SearchOption.AllDirectories))
.ToList();
which does not need to load all files into memory until it starts processing. when you are working with many files and directories, EnumerateFiles can be more efficient.
I am not sure what filter is in your code, but here is a simple example to search a directory.
string path = "C:\\myFolder1\\myFolder2";
DirectoryInfo dir = new DirectoryInfo(path);
FileInfo[] files;
files = dir.GetFiles("*.*", SearchOption.AllDirectories);
Maybe your path is wrong?
But the AllDirectories options begins at your specified path.
I am having an issue with trying to make a list by searching through a file structure. Was trying to make a basic c# console program that would just run and do this.
My structure is organize like the following.
My Network \
X1 \
Users \
(many many user folders) \
Search for a specific sub folder \
make a list in a text file of any folders within this sub folder
So i have to be able to search every user folder and then check for a folder (this will be the same every time) Then make a list of the found folders within that sub folder with the following format
username (name of the user folder) >> Name of folder within the specific folder.
its been a terribly long time since i have had to try anything with searching within a file structure so blanking on this terribly.
**************** EDIT!!!!!
Thanks for the info and links. Working on this now but wondering if this makes sense and would work. Don't want to just test it before i make sure it looks like something that wouldn't just screw up.
TextWriter outputText = new StreamWriter(#"C:\FileList.txt", true);
outputText.WriteLine("Starting scan through user folder");
string path = #"\\X1\users";
string subFolder = "^^ DO NOT USE - MY DOCS - BACKUP ^^";
string [] user_folders = Directory.GetDirectories(path);
foreach (var folder in user_folders)
{
string checkDirectory = folder + "\\" + subFolder;
if (Directory.Exists(checkDirectory) == true)
{
string [] inner_folders = Directory.GetDirectories(checkDirectory);
foreach (var folder2 in inner_folders)
{
outputText.WriteLine(folder2);
}
}
}
outputText.WriteLine("Finishing scan through user folder");
outputText.Close();
Fixed and working!!!! had to change the string [] lines, to make it .GetDirectories instead of .GetFiles!!
As Bali C mentioned, the Directory class will be your friend on this one. The following examples should get you started.
From: http://social.msdn.microsoft.com/Forums/en-US/Vsexpressvcs/thread/3ea19b83-b831-4f30-9377-bc1588b94d23/
//Obviously you'll need to define the correct path.
string path = #"My Network\X1\Users\(many many user folders)\Search for a specific sub folder \";
// Will Retrieve count of all files in directry and sub directries
int fileCount = Directory.GetFiles(path, "*.*", SearchOption.AllDirectories).Length;
// Will Retrieve count of all files in directry but not sub directries
int fileCount = Directory.GetFiles(path, "*.*", SearchOption.TopDirectory).Length;
// Will Retrieve count of files .txt extensions in directry and sub directries
int fileCount = Directory.GetFiles(path, "*.txt", SearchOption.AllDirectories).Length;
If you need to search the /Users/ folder for certain people, or certain conditions you could do the following:
string path = #"PATH_TO_USERS_DIRECTORY";
string [] user_folders = Directory.GetFiles(path);
foreach(var folder in user_folders)
{
if folder == "MyFolder";
Process(folder); //Search the directory here.
}
Try the following implementation. This will just write to the console:
const string root = "<<your root path>>";
const string directoryToLookFor = "<<the folder name you are looking for>>";
foreach (var directory in Directory.EnumerateDirectories(root, "*.*", SearchOption.TopDirectoryOnly))
{
var foundDirectory = Directory.EnumerateDirectories(directory, directoryToLookFor, SearchOption.TopDirectoryOnly).FirstOrDefault();
if (!String.IsNullOrEmpty(foundDirectory))
{
var filesInside = Directory.GetFiles(foundDirectory);
foreach (var file in filesInside)
{
Console.WriteLine(file);
}
}
}
Or you could just do:
foreach (var foundDirectory in Directory.EnumerateDirectories(root, directoryToLookFor, SearchOption.AllDirectories))
{
var filesInside = Directory.GetFiles(foundDirectory);
foreach (var file in filesInside)
{
Console.WriteLine(file);
}
}
Which would search within all subdirectories without you having to iterate over the users' folders.
I have the following code, which will process the folder and files in that folder when a user drops it onto a button on my C# Winforms application window. This code works fine:
List<string> filepaths = new List<string>();
foreach (var s in (string[])e.Data.GetData(DataFormats.FileDrop, false))
{
if (Directory.Exists(s))
{
//Add files from folder
filepaths.AddRange(Directory.GetFiles(s));
}
else
{
//Add filepath
filepaths.Add(s);
}
}
However, if there is another folder inside of the main folder (sub-folder), it does not detect that sub-folder and list the files inside of the sub-folder.
Can someone please show me how to detect the name of the sub-folder and the files in the sub-folder as well?
Edit: Would something like this work?
string[] fileList = Directory.GetFiles(#s, "*.*", SearchOption.AllDirectories);
Simalar to Frazell but I like to use file and directory info types like:
Edit: Added a ProcessFile() method
public void ProcessFolder(DirectoryInfo dirInfo)
{
//Check for sub Directories
foreach (DirectoryInfo di in dirInfo.GetDirectories())
{
//Call itself to process any sub directories
ProcessFolder(di);
}
//Process Files in Directory
foreach (FileInfo fi in dirInfo.GetFiles())
{
//Do something with the file here
//or create a method like:
ProcessFile(fi)
}
}
public void ProcessFile(FileInfo fi)
{
//Do something with your file
Debug.Print(fi.FullName);
//...
}
You need to use Directory.GetDirectories() to pull back the subdirectories then loop through them similar to what you're already doing.
// Process all files in the directory passed in, recurse on any directories
// that are found, and process the files they contain.
public static void ProcessDirectory(string targetDirectory)
{
// Process the list of files found in the directory.
string [] fileEntries = Directory.GetFiles(targetDirectory);
foreach(string fileName in fileEntries)
ProcessFile(fileName);
// Recurse into subdirectories of this directory.
string [] subdirectoryEntries = Directory.GetDirectories(targetDirectory);
foreach(string subdirectory in subdirectoryEntries)
ProcessDirectory(subdirectory);
}

hi
i am creating a application and i want to know the each and every file which is present under that one folder .i.e. how can i iterate through a root directory and get the each files visit at list once.
If you just need to list them all at once, you can just use the overload for GetFiles that includes the option.
string[] filePaths = Directory.GetFiles(#"c:\MyDir\", "*.*", SearchOption.AllDirectories);
Obviously, in a web app you wouldn't likely have access to "c:\MyDir", so you can replace that with a variable holding the results of a MapPath call like so:
var rootDir = Server.MapPath("~/App_Data");
Use the Directory.EnumerateFiles(String, String, SearchOption) function with SearchOption.AllDirectories:
foreach (var file in Directory.EnumerateFiles(#"c:\", "*.txt", SearchOption.AllDirectories))
{
// Do stuff here
}
EnumerateFiles method is way faster than GetFiles method since it actually just returns the enumerator and does not actually access the files until they are red.
You can use the DirectoryInfo and FileInfo classes as well as a recursive function.
void Main()
{
DirectoryInfo info = new DirectoryInfo(#"C:\Personal");
ListContents(info);
}
public void ListContents(DirectoryInfo info)
{
foreach(var dir in info.GetDirectories())
{
ListContents(dir);
}
foreach(var file in info.GetFiles())
{
Console.WriteLine(file.FullName);
}
}
