how to display the statistics about all the files in a folder in C# [closed]
(1 answer)
Closed 9 years ago.
I'm writing an console application to show folder statistics on C:\windows, and show the total files in there is there anyways it can be simplified and link the file type with the user!. This is what I've got so far:
{
String extention = String.Empty;
// Prompt the user to enter extention type
Console.Write("Please enter extention type: ");
extention = Console.ReadLine();
// This gets the Folder location which in this case is C:\\windows
DirectoryInfo root = new DirectoryInfo(Environment.GetFolderPath(Environment.SpecialFolder.Windows));
// This is basicly the bit that collects the data after the user has entered the extention type
FileInfo[] executables = root.GetFiles("*exe");
foreach (var exe in executables)
{
//This will show the word txt in the console window
Console.WriteLine(exe.Name);
}
}
}
}
{
String extention2 = String.Empty;
// Prompt the user to enter extention type
extention2 = Console.ReadLine();
// This gets the Folder location which in this case is C:\\windows
DirectoryInfo root2 = new DirectoryInfo(Environment.GetFolderPath(Environment.SpecialFolder.Windows));
FileInfo[] text = root2.GetFiles("*.txt");
foreach (var txt in text)
{
//This will show the word txt in the console window
Console.WriteLine(txt.Name);
}
}
String extention4 = String.Empty;
// Prompt the user to enter extention type
extention4 = Console.ReadLine();
// This gets the Folder location which in this case is C:\\windows
DirectoryInfo root4 = new DirectoryInfo(Environment.GetFolderPath(Environment.SpecialFolder.Windows));
FileInfo[] windows = root4.GetFiles("*.win");
foreach (var win in windows)
{
//This will show the word txt in the console window
Console.WriteLine(win.Name);
}

Try using: new DirectoryInfo("C:\\Windows")
If you want to get a list of the files in that directory then call:
EnumerateFiles("*",SearchOption.AllDirectories)
on the DirectoryInfo object

Look at this:
"How to: Get Information About Files, Folders, and Drives (C# Programming Guide)"
http://msdn.microsoft.com/en-us/library/6yk7a1b0.aspx
For example:
// Get the files in the directory and print out some information about them.
System.IO.FileInfo[] fileNames = dirInfo.GetFiles("*.*");
foreach (System.IO.FileInfo fi in fileNames)
{
Console.WriteLine("{0}: {1}: {2}", fi.Name, fi.LastAccessTime, fi.Length);
}
You can change the Console.WriteLine to the format that you want...
Update:
System.IO.DriveInfo di = new System.IO.DriveInfo(#"C:\");
// Get the root directory
System.IO.DirectoryInfo dirInfo = di.RootDirectory;
// And then you can do .GetFiles()
System.IO.FileInfo[] fileNames = dirInfo.GetFiles("*.*");

Accessing files within child directories

I am trying to access the files in the images directory that lies within another directory but when I run my code it doesn't print out anything:
string path = #"C:\Path";
DirectoryInfo DFolder = new DirectoryInfo(path);
Collection cDetails = new Collection(DFolder);
string DFPath = DFolder.Name;
DirectoryInfo imDetails = new DirectoryInfo(imPath);
// Get Desired Directories
List<string> directoryFilter = new List<string> {"images", "videos", "RAW"};
List<DirectoryInfo> directoryList = DFolder
.GetDirectories("*", SearchOption.AllDirectories)
.Where(x => directoryFilter.Contains(x.Name.ToLower()))
.ToList();
string dpath = directoryList.ToString();
foreach (DirectoryInfo record in directoryList)
{
foreach (FileInfo file in record.GetFiles(#"*", SearchOption.TopDirectoryOnly))
{
Console.WriteLine(file); //It compiles but doesn't print anything on the console
}
}
Note: This isn't really an answer, so I'll delete it shortly, but wanted to give some sample code to test with in case it helps.
Your code works fine for me, so it seems that the problem is that either the directories don't exist, or they don't contain any files.
Here's a test program you can run which creates a bunch of directories under c:\temp, some of which have the names we care about. The names we care about are also found at different levels of depth in the path, yet they are all discovered:
static void CreateTestPathsAndFiles()
{
// Paths to create for testing. We will put a file in each directory below,
// but our search code should only print the file paths of those files that
// are directly contained in one of our specially-named folders
var testPaths = new List<string>
{
#"c:\temp\dummy1",
#"c:\temp\dummy1\raw", // This should print
#"c:\temp\dummy2",
#"c:\temp\dummy2\extra",
#"c:\temp\dummy3",
#"c:\temp\dummy3\dummy31",
#"c:\temp\dummy3\dummy32\raw", // This should print
#"c:\temp\extra",
#"c:\temp\images", // This should print
#"c:\temp\notUsed",
#"c:\temp\notUsed\videos", // This should print
#"c:\temp\raw", // This should print
#"c:\temp\videos\dummy1",
};
// Just something to make a unique file name
int fileId = 0;
// for testing, ensure that the directories exist and contain some files
foreach(var testPath in testPaths)
{
// Create the directory
Directory.CreateDirectory(testPath);
// Add a file to it
File.CreateText(Path.Combine(testPath, $"TempFile{fileId}.txt"))
.Write($"Dummy text in file {fileId}");
// Increment our file counter
fileId++;
}
}
static void Main(string[] args)
{
// Create our paths and files for testing
CreateTestPathsAndFiles();
// Now set our root directory, search for all folders matching our
// special folder names, and print out the files contained in them
var path = #"C:\Temp";
var directoryFilter = new List<string> {"images", "videos", "raw"};
// Get ALL sub-directories under 'path' whose name is in directoryFilter
var subDirectories = new DirectoryInfo(path)
.GetDirectories("*", SearchOption.AllDirectories)
.Where(x => directoryFilter.Contains(x.Name.ToLower()));
foreach (DirectoryInfo subDir in subDirectories)
{
foreach (FileInfo file in subDir.GetFiles(#"*", SearchOption.TopDirectoryOnly))
{
// We're using the FullName so we see the whole file path in the output
Console.WriteLine(file.FullName);
}
}
GetKeyFromUser("\nDone! Press any key to exit...");
}
Output
Note that the 5 files we expected to find are listed, but no others:
foreach (FileInfo file in record.GetFiles(#"*", SearchOption.TopDirectoryOnly))
{
Console.WriteLine(file); //It compiles but doesn't print anything on the console
}
SearchOption.TopDirectoryOnly will only search files in C://Path/images but not its subfolders.
a possible fix for this is to simply change your 2nd foreach loop to look like this:
foreach (FileInfo file in record.GetFiles(#"*", SearchOption.AllDirectories))
{
Console.WriteLine(file); //It compiles but doesn't print anything on the console
}
Edit:
Using SearchOption.AllDirectories as parameter is supposed to catch all cases of subfolders within your subfolder e.g. something like C://images//dir//somefile.txt instead of only taking the files within the topdirectory(in this case C://images). Which is(as i understood your question) exactly the kind of behaviour you were looking for.
Full code:
{
static void Main(string[] args)
{
// Directory Info
string path = #"C:\Path";
DirectoryInfo DFolder = new DirectoryInfo(path);
string DFPath = DFolder.Name;
// Get Desired Directories
List<string> directoryFilter = new List<string> { "images", "videos", "raw" };
List<DirectoryInfo> directoryList = DFolder.GetDirectories("*", SearchOption.AllDirectories).Where(x => directoryFilter.Contains(x.Name.ToLower())).ToList();
string dpath = directoryList.ToString();
foreach (DirectoryInfo record in directoryList)
{
foreach (FileInfo file in record.GetFiles(#"*", SearchOption.AllDirectories)) //searches directory record and its subdirectories
{
Console.WriteLine(file);
}
}
}
Final Edit: Sample output given the following structure:
C://Path//images//images.somefile.txt
C://Path//images//temp//images.temp.somefile.txt
C://Path//raw//raw.somefile.txt
C://Path//vidoes//videos.somefile.txt

Application: Application Launcher, can't Move directory, it's being used by another process

I'm writing application launcher as a Window Application in C#, VS 2017. Currently, having problem with this piece of code:
if (System.IO.Directory.Exists(extractPath))
{
string[] files = System.IO.Directory.GetFiles(extractPath);
string[] dirs = Directory.GetDirectories(extractPath);
// Copy the files and overwrite destination files if they already exist.
foreach (string s in files)
{
// Use static Path methods to extract only the file name from the path.
var fileName = System.IO.Path.GetFileName(s);
var destFile = System.IO.Path.Combine(oldPath, fileName);
System.IO.File.Move(s, destFile);
}
foreach (string dir in dirs)
{
//var dirSplit = dir.Split('\\');
//var last = dirSplit.Last();
//if (last != "Resources")
//{
var fileName = System.IO.Path.GetFileName(dir);
var destFile = System.IO.Path.Combine(oldPath, fileName);
System.IO.Directory.Move(dir, destFile);
//}
}
}
I'm getting well known error
"The process cannot access the file 'XXX' because it is being used by another process."
I was looking for solution to fix it, found several on MSDN and StackOvervflow, but my problem is quite specific. I cannot move only 1 directory to another, which is Resources folder of my main application:
Here is my explanation why problem is specific:
I'm not having any issues with moving other files from parent directory. Error occurs only when loop reaches /Resources directory.
At first, I was thinking that it's beeing used by VS instantion, in which I've had main app opened. Nothing have changed after closing VS and killing process.
I've copied and moved whole project to another directory. Never opened it in VS nor started via *.exe file, to make sure that none of files in new, copied directory, is used by any process.
Finally, I've restarted PC.
I know that this error is pretty common when you try to Del/Move files, but in my case, I'm sure that it's being used only by my launcher app. Here is a little longer sample code to show what files operation I'm actually doing:
private void RozpakujRepo()
{
string oldPath = #"path\Debug Kopia\Old";
string extractPath = #"path\Debug Kopia";
var tempPath = #"path\ZipRepo\RexTempRepo.zip";
if (System.IO.File.Exists(tempPath) == true)
{
System.IO.File.Delete(tempPath);
}
System.IO.Compression.ZipFile.CreateFromDirectory(extractPath, tempPath);
if (System.IO.Directory.Exists(oldPath))
{
DeleteDirectory(oldPath);
}
if (!System.IO.Directory.Exists(oldPath))
{
System.IO.Directory.CreateDirectory(oldPath);
}
if (System.IO.Directory.Exists(extractPath))
{
string[] files = System.IO.Directory.GetFiles(extractPath);
string[] dirs = Directory.GetDirectories(extractPath);
// Copy the files and overwrite destination files if they already exist.
foreach (string s in files)
{
// Use static Path methods to extract only the file name from the path.
var fileName = System.IO.Path.GetFileName(s);
var destFile = System.IO.Path.Combine(oldPath, fileName);
System.IO.File.Move(s, destFile);
}
foreach (string dir in dirs)
{
//var dirSplit = dir.Split('\\');
//var last = dirSplit.Last();
//if (last != "Resources")
//{
var fileName = System.IO.Path.GetFileName(dir);
var destFile = System.IO.Path.Combine(oldPath, fileName);
System.IO.Directory.Move(dir, destFile);
//}
}
}
string zipPath = #"path\ZipRepo\RexRepo.zip";
ZipFile.ExtractToDirectory(zipPath, extractPath);
}
And now, my questions:
Can it be related to file types (.png, .ico, .bmp) ?
Can it be related to fact, that those resources files are being used like, as, for example .exe file icon in my main application? Or just because those are resources files?
Is there anything else what I'm missing and what can cause the error?
EDIT:
To clarify:
There are 2 apps:
Main Application
Launcher Application (to launch Main Application)
And Resources folder is Main Application/Resources, I'm moving it while I'm doing application version update.
It appeared that problem is in different place than in /Resources directory. Actually problem was with /Old directory, because it caused inifinite recurrence.

Read multiple .txt files at once with console command

Hi I'm programing a console application that reads in the text of a .txt file and then calculates the Flesch Score (how easy a text is to read). It's already able to get started by the console by typing in the path and some parameters f.e. -f "filename" or -e for english. Now I want to read in multiple textfiles with the command -f "testfile*.txt. The * means that it doesn't matter what is written after f.e. enumeration. How can I achieve that with a console command? Correct me if I'm wrong with something I'm kind of new to programing :)
Here's how I am doing it:
string[] parameters = new string[] { "-f", "-e", "-g" };
Flesch_Reading_Ease.FleschScore.Language lang = FleschScore.Language.Undefined;
string filename = "";
foreach (string arg in args)
{
switch (arg.Trim().ToLower())
{
case "-e":
lang = Flesch_Reading_Ease.FleschScore.Language.English;
break;
case "-g":
lang = Flesch_Reading_Ease.FleschScore.Language.German;
break;
case "-f":
break;
default:
{
if (File.Exists(arg))
filename = arg;
}
break;
}
}
If you use the Directory.GetFiles method it will return a list of files that match the wildcard:
string[] files = Directory.GetFiles(folder, arg);
where folder is the name of the directory you're looking in. You'll either have to assume the current folder "." or split the path from the input arguments.
You can then loop over this list:
foreach (var file in files)
{
// Do your processing
}

Searching through a file structure to count items in a subfolder

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.

Directory is not reading properly

I am having One Directory
C:\Kuldeep\kverma\kver\
After that It consists thousands of Folders with Different name .Each Folder consists Different Excel File . I need to read Each Files from Different Folders .
I want To read All The Folders Path from C:\Kuldeep\kverma\kver\ Folder.
I used below code for getting the folders name with path ..
string path = #"C:\Kuldeep\kverma\kver\";
DirectoryInfo dir = new DirectoryInfo(path);
Console.WriteLine("File Name Size Creation Date and Time");
Console.WriteLine("========");
foreach (DirectoryInfo dirinfo in dir.GetDirectories())
{
String name = dirinfo.Name;
String pth = dirinfo.FullName;
Console.WriteLine( name, pth);
}
Total 10700 folders are there in C:\Kuldeep\kverma\kver\ Directory But It is reading only 54 Folder..
Please provide me any solution for Reading Folder name and location Also Reading File from Each Folder in Single Shot .
You should put a try catch around the GetDirectories call to handle the exceptions in the below post.
That might give you a clue as to why it is not enumerating properly.
http://msdn.microsoft.com/en-us/library/c1sez4sc.aspx
Try a recursive approach:
namespace ConsoleApplication1
{
using System;
using System.Collections.Generic;
using System.IO;
class Program
{
public static IList<DirectoryInfo> dirs;
static void Main(string[] args)
{
dirs = new List<DirectoryInfo>();
var dir = new DirectoryInfo(#"c:\tmp");
GetDirs(dir);
Console.WriteLine(dirs.Count);
}
public static void GetDirs(DirectoryInfo root)
{
foreach (var directoryInfo in root.GetDirectories())
{
dirs.Add(directoryInfo);
GetDirs(directoryInfo);
}
}
}
}
Now I'm not sure what hidden dangers might be lurking because of this (Stack overflow exceptions, access denied?) so I'd recommend placing a try..catch block in the foreach loop to help you out.
If you want to view the contents of every sub directory:
// Flatten out the directory structure in to a string array.
var directoryList = Directory.GetDirectories("<<RootPath>>", "*", SearchOption.AllDirectories);
foreach (var directory in directoryList)
{
DirectoryInfo info = new DirectoryInfo(directory);
}
edited with the questions code updated:
string path = #"C:\Kuldeep\kverma\kver\";
string[] directoryArray = Directory.GetDirectories(path, "*", SearchOption.AllDirectories);
foreach (var directory in directoryArray)
{
DirectoryInfo dirinfo = new DirectoryInfo(directory);
String name = dirinfo.Name;
String pth = dirinfo.FullName;
Console.WriteLine(name, pth);
}
