I was trying to make a program to clean out some directories on my NAS and I noticed that a lot of folders contained nested rar and zip files and I have plenty of space to unpack them. The program should ask the user for a directory to be cleaned then unpack all rars then delete all of the rars. I'm trying to use UnRAR DLL and I cant even get the rars to unpack. I realize I'm having an issue where visual studio 2022 is refusing to recognize the Unrar DLL in the "using" command. Because of that I've been unable to unpack a single file. This is one my first useful programs so if im missing something basic I understand.
This is my initial attempt:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using System.Diagnostics;
using UnRAR;
namespace Cleaning
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Enter Directory To Be Cleaned");
string rar_path = Console.ReadLine();
string[] Rars = Directory.GetFiles(rar_path, "*.rar", SearchOption.AllDirectories);
foreach (string rar in Rars)
{
string source = rar;
string dest = "C:\\Users\\Kaleb\\OneDrive\\Desktop\Test Area";
UnRAR unrar = new UnRAR();
unrar.Password = "password_of_myarchive";
unrar.Open(#source, UnRAR.OpenMode.Extract);
while (unrar.ReadHeader())
{
unrar.ExtractToDirectory(#dest);
}
unrar.Close();
}
}
}
}
For reference I have added the UnRAR DLL to the project folder.
SO I was able to get it working with the source code from the great people over at SharpCompress and utilizing their source I've got the following stable build.
using SharpCompress.Archives;
using SharpCompress.Archives.Rar;
using SharpCompress.Common;
using System;
using System.IO;
using System.Linq;
using System.Globalization;
namespace ConsoleApp3
{
public class Program
{
static void Main(string[] args)
{
for (; ; )
{
Console.WriteLine("Enter E to extract all directories in file path");
Console.WriteLine("Enter D to delete all Archives in file path");
Console.WriteLine("REMEMBER TO ALWAYS EXTRACT BEFORE DELETING");
string option = Console.ReadLine();
if (option == "e" || option == "E")
{
Console.WriteLine("Enter Directory To Be Cleaned");
//as a warning this will extract all files from any rar in the slected driectory one at a time in order.
//if a rar is broken it will halt the program until the offendin rar is deleted best way to find is to see what has been extracted so far and go from there
//or one could also limit the directory in order to refine the number of rars to look for
string rar_path = Console.ReadLine();
string[] Rars = Directory.GetFiles(rar_path, "*.rar", SearchOption.AllDirectories);
foreach (string rar in Rars)
{
var DirectoryFinal = Path.GetDirectoryName(rar);
using (var archive = RarArchive.Open(#rar))
{
foreach (var entry in archive.Entries.Where(entry => !entry.IsDirectory))
{
entry.WriteToDirectory(#DirectoryFinal, new ExtractionOptions()
{
ExtractFullPath = true,
Overwrite = true
});
}
};
}
}
else if (option == "d" || option == "D")
{
Console.WriteLine("Enter Directory To Be Cleaned");
//be careful with this i would recomend extracting and then chekcing everything first
string rar_path = Console.ReadLine();
string[] TobeDeleted = Directory.GetFiles(rar_path, "*.r*", SearchOption.AllDirectories);
foreach (string rarstobedeleted in TobeDeleted)
{
File.Delete(rarstobedeleted);
}
}
else
{
Console.WriteLine("Thats not an option try again");
}
Console.WriteLine("Cleaning Complete.");
;
}
}
}
}
This work effectively for rar files only for the time being but will effectively clean up any directories where someone may have downloaded a large amount of files stored in separated rars

I want to make a program in C# that replaces the text of all files in a folder.
I tried this:
using System;
using System.IO;
namespace Stackoverflow
{
class Program
{
static void Main(string[] args)
{
String[] files = Directory.GetFiles(#"C:\Users\test\folder", "*", SearchOption.AllDirectories);
File.WriteAllText(files, "Test");
}
}
}
But I get an error that says that it cannot be converted from "string[]" to "string"
Does anyone know how to solve this?
Instead of
File.WriteAllText(files, "Test");
try using
files.ForEach(file => File.WriteAllText(file, "Test"));
This should work.
EDIT: Or as Heinzi commented, you can similarly solve it in a loop instead of a lambda expression:
foreach (string file in files)
{
File.WriteAllText(file, "Test");
}
I want to compress every video within every drive and its sub-directories so the code I have used so far finds each drive and looks for .mp4 locations. Then it uses that list of strings to compress each file but it comes up with this error at:
var mediaInfo = FFProbe.Analyse(filePath: d)
and
.FromFileInput(d, verifyExists: true)
System.ComponentModel.Win32Exception: 'The system cannot find the file specified'
I checked what the .Analyse needs and it is a string and d is a string which has the right path location C:\\Users\\Helix\\Desktop\\apartment\\5 Little Monkeys Swinging In The Tree.mp4" which I thought would work but it does not seem to like it. What am I doing wrong?
I am also curious as to if GetDrives() works on network drives? And if it does would two servers running this code conflict when grabbing the same file at the same time?

foreach (DriveInfo d in allDrives)
{
//The d.Name output has "Drive C:\" as the output. remove the "Drive " part first
var replacement = d.Name.Replace("Drive ", "");
/*Grab each files location with the Directory tool from the earlier IO libary.

options can be found in more detail by seaching for GetFiles C#*/
string[] files = Directory.GetFiles(#"C:\Users\Helix\Desktop\apartment\","*.mp4", SearchOption.AllDirectories);// replacement//AllDirectories
//Convert the array to a list
List<string> templist = files.ToList();
//Add them to the earlier empty list we made
file.AddRange(templist);
}
//Now that we have paths to all the files we need we can now compress them
foreach (string d in file)
{
var mediaInfo = FFProbe.Analyse(filePath: d);
//Open the video file with MediaToolkit

You need to download both ffprobe.exe and ffmpeg.exe.
The executable is missing not the media one.
I have the following c# Console app I would run this in ssis but i am using a couple of PDF manipulating librarys. so i am going to call an exe from my ssis package while passing in a file path.
But i am getting the following error when trying to run via the exe.
Unhandled Exception: System.IndexOutOfRangeException: Index was
outside the bounds of the array. at ConsoleApp.program.Main(String[]
args) line 87
BUT if i run in debug it works fine. Once i get it working on its own via the exe, i want to pass the filepath as a parameter in ssis.
see c# below
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using org.apache.pdfbox.pdmodel;
using org.apache.pdfbox.util;
using System.IO;
namespace PDF_Read_ConsoleApp
{
class Program
{
public static void FilePath(string path)
{
//Console.WriteLine("Please enter full pdf path \n\n ");
//path = Console.ReadLine();
string fp;
fp = #path;
string[] files = Directory.GetFiles(path, "*.pdf");
foreach (string s in files)
{
string txtOutput = s.Replace(".pdf", ".txt");
if (File.Exists(txtOutput))
{
File.Delete(txtOutput);
}
string output;
PDDocument doc = null;
try
{
doc = PDDocument.load(s);
PDFTextStripper stripper = new PDFTextStripper();
stripper.getText(doc);
output = stripper.getText(doc);
StreamWriter NewFile;
NewFile = new StreamWriter(txtOutput);
//NewFile.Write(output.ToString());
NewFile.Write(output.ToString());
NewFile.Close();
}
finally
{
//if (doc != null)
//{
doc.close();
// Console.WriteLine("\n\n File saveed - ({0} ", txtOutput);
//}
}
}
}
static void Main(string[] args)
{
args[0] = #"C:\SSIS_Packages\PDF_Import\PDF_Import\PO_pdfs"; //// TESTING FILE PATH1
FilePath(args[0]);
}
}
}

I have managed to get it working, I need to enter an argument within the debug screen, see information in URL below
Console app arguments, how arguments are passed to Main method
THank you for everyone's comments
I would like my program to read sub-folders from folder in my solution, but i don't know how to read folder names. I can only find, how to read file names and this is not hard to get to work, but with folders, this doesn't seem to work the same way.
Basically I want to load from "Paevik" (2) sub-folders.
E: I forgot to mention, that I want that list into my comboBox
There is System.IO.Directory.EnumerateDirectories(string Path)-method. It returns a collections with directories. Example:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
class Program
{
private static void Main(string[] args)
{
try
{
string dirPath = #"\\archives\2009\reports";
List<string> dirs = new List<string>(Directory.EnumerateDirectories(dirPath));
foreach (var dir in dirs)
{
Console.WriteLine("{0}", dir.Substring(dir.LastIndexOf("\\") + 1));
}
Console.WriteLine("{0} directories found.", dirs.Count);
}
catch (UnauthorizedAccessException UAEx)
{
Console.WriteLine(UAEx.Message);
}
catch (PathTooLongException PathEx)
{
Console.WriteLine(PathEx.Message);
}
}
}
See MSDN.
Try DirectoryInfo.EnumerateDirectories Method
http://msdn.microsoft.com/en-us/library/dd413235.aspx
You can use "GetDirectories" to retrieve an array containing full names of all subdirectories.
string[] subdirectories = Directory.GetDirectories("Full path of your parent folder");
See sample on MSDN page.
Moving files to the recycle bin and emptying the recycle bin are well documented, but how can a file be programmatically restored from the recycle bin?
There seems not to be a solution in pure C#. You most likely have to resort to P/Invoke.
This article presents a solution in C++ using the SHFileOperation API.
The only other reference to this beyond the previously mentioned link to codeproject that I can see mentions this:
Call SHGetFolderLocation passing CSIDL_BITBUCKET.
Then you can manipulate that folder as usual.
You'll have to create an interop for the SHGetFolderLocation function.
CSIDL_BITBUCKET being the CSIDL ("constant special item ID list") value for the virtual Recycle Bin folder. The quote is taken from here, and will involve interop with the Windows shell. MSDN also mentions that this function has been deprecated in favour of another in Vista.
Hope below code will work to restore the files. Please make sure, STA Calls only supported for shell calls
