Making an iso file from a directory using DiscUtils - c#

Iam trying to build an iso file from a directory with discutils. This code works fine with a couple of files but after a while i throws an exception stating that "An object with the same key already exists" at "isoBuilder.AddFile(fileOnIso,br.BaseStream);". I don't understand why this happens can someone please shed some light?
public void AddtoISO(string directory,string isoFile)
{
BinaryReader br;
long bytesRemain = 0;
long totalBytesWritten = 0;
DirectoryInfo rootDirToAdd = new DirectoryInfo(sourceName);
DirectoryInfo currentDirToAdd = new DirectoryInfo(directory);
try
{
foreach (FileInfo file in currentDirToAdd.GetFiles())
{
string fileFullPath = file.FullName;
string fileOnIso = fileFullPath.Substring(fileFullPath.IndexOf(rootDirToAdd.Name) + rootDirToAdd.Name.Length + 1);
Console.WriteLine(fileOnIso);
br = new BinaryReader(file.OpenRead());
while(totalBytesWritten < file.Length)
{
bytesRemain = file.Length - totalBytesWritten;
br.ReadBytes(blockSize);
isoBuilder.AddFile(fileOnIso,br.BaseStream);
if(bytesRemain<blockSize)
{
totalBytesWritten += bytesRemain;
totalBytesAdded += bytesRemain;
}
else
{
totalBytesWritten += blockSize;
totalBytesAdded += blockSize;
}
}
itemsAdded++;
totalBytesWritten = 0;
}
foreach (DirectoryInfo subdir in currentDirToAdd.GetDirectories())
{
string folderFullPath = subdir.FullName;
string folderOnIso = folderFullPath.Substring(folderFullPath.IndexOf(rootDirToAdd.Name) + rootDirToAdd.Name.Length + 1);
isoBuilder.AddDirectory(folderOnIso);
itemsAdded++;
AddtoISO(subdir.FullName,isoFile,ctoken);
}
isoBuilder.Build(isoFile);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
Console.WriteLine(ex.StackTrace);
}
}
Update
An other possible implementation avoiding streams, the drawback is that it takes too much time (over 30 mins) on a 3GB iso which when built with ultraiso for example, it takes aprox 4 mins.. any ideas?
public void AddtoISO(string directory,string isoFile)
{
try
{
DirectoryInfo rootDirToAdd = new DirectoryInfo(sourceName);
DirectoryInfo currentDirToAdd = new DirectoryInfo(directory);
foreach (FileInfo file in currentDirToAdd.GetFiles())
{
string fileOnHdd = file.FullName;
string fileOnIso = fileOnHdd.Substring(fileOnHdd.IndexOf(rootDirToAdd.Name) + rootDirToAdd.Name.Length + 1);
Console.WriteLine(fileOnIso);
isoBuilder.AddFile(fileOnIso,fileOnHdd);
itemsAdded++;
}
foreach (DirectoryInfo subdir in currentDirToAdd.GetDirectories())
{
itemsAdded++;
AddtoISO(subdir.FullName,isoFile,ctoken);
}
isoBuilder.Build(isoFile);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
Console.WriteLine(ex.StackTrace);
}
}
Update:
The exception is thrown when ever the directory structure is the following:
\boot\boot
It seems like it creates the key for boot directory and when it encounters boot.ext file it falsely thinks that it is a double addition. In other words when the files contains the name of its containing directory.

Problem on KNOPPIX\KNOPPIX
Update 2
At last some progress.. the error is not in any of the given paths but im my assumption that i had to keep calling isobuilder.Addfile() until the filestream has been added to the iso entirely.
I just had to move:
isoBuilder.AddFile(fileOnIso,br.BaseStream);
Before the foreach closing bracket. This way it will no have to be added again and again in the iso.
One final problem is at the line
isoBuilder.Build(isoFile);
Where it complains about the file being closed. I tried to correct it with:
FileInfo fi = new FileInfo(isoFile);
isoBuilder.Build(fi.OpenWrite());
But it didnt help. Please someone give me the final push to solve it.

I know this is very OLD but I thought Id post if anyone else needed help with this in future.
Below is a fast and efficient function I use to build an ISO using DiscUtils.Iso9660
public string CreateIsoImage(string sourceDrive, string targetIso, string volumeName)
{
try
{
var srcFiles = Directory.GetFiles(sourceDrive, "*", SearchOption.AllDirectories);
var iso = new CDBuilder
{
UseJoliet = true,
VolumeIdentifier = volumeName
};
foreach (var file in srcFiles)
{
var fi = new FileInfo(file);
if (fi.Directory.Name == sourceDrive)
{
iso.AddFile($"{fi.Name}", fi.FullName);
continue;
}
var srcDir = fi.Directory.FullName.Replace(sourceDrive, "").TrimEnd('\\');
iso.AddDirectory(srcDir);
iso.AddFile($"{srcDir}\\{fi.Name}", fi.FullName);
}
iso.Build(targetIso);
return "Success";
}
catch (Exception ex)
{
return ex.Message;
}
}
Usage:
var res = CreateIsoImage("D:\\", "C:\\Temp\\MyIsoImage.iso", "MyVolumeName");
MessageBox.Show(res);

An item with the same key has already been added Ionic.Zip

Good afternoon, please tell me how can I add files with the same name to the archive? To be like copying, the file becomes file(1).* and there are two files file and file(1) . I am using Ionic.Zip
string BackupDir = #"C:\Users\Desktop\dir\backup.zip";
string PathToFolder = #"C:\Users\Desktop\dir";
string[] AllFiles = Directory.GetFiles(PathToFolder, "*.*", SearchOption.AllDirectories);
using (ZipFile zip = new ZipFile(BackupDir, Encoding.UTF8))
{
foreach (string file in AllFiles)
{
try
{
DateTime FileCreationTime = File.GetCreationTime(file);
if (FileCreationTime >= DateTime.Now - new TimeSpan(60, 0, 0, 0))
{
Console.WriteLine(file);
zip.CompressionLevel = Ionic.Zlib.CompressionLevel.BestSpeed;
zip.AddFile(file, "");
}
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
zip.Save(BackupDir);
}
}
Try this:
//keep track of fileNames
var fileNames = new HashSet<string>(StringCompaer.OridialIgnoreCase);
foreach (string file in AllFiles)
{
try
{
DateTime FileCreationTime = File.GetCreationTime(file);
if (FileCreationTime >= DateTime.Now - new TimeSpan(60, 0, 0, 0))
{
Console.WriteLine(file);
zip.CompressionLevel = Ionic.Zlib.CompressionLevel.BestSpeed;
var fileName = Path.GetFileName(file);
if (fileNames.Add(fileName))
zip.AddFile(file, ""); //fileName could be added to fileNames = it is unique
else
{
//start with 1
int counter = 1;
//loop till you found a fileName thats not occupied
while (true)
{
//build the new file name
var newFileName = $"{Path.GetFileNameWithoutExtension(fileName)} - {counter}{Path.GetExtension(fileName}";
if (fileNames.Add(newFileName))
{
fileName = newFileName; //use the new fileName
break; //break the loop
}
//increase counter if newFileName is already in the list fileNames
counter++;
}
var zipFileEntry = zip.AddFile(file, "");
zipFileEntry.FileName = fileName;
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
zip.Save(BackupDir);
}
Check if file exists and add suffix to it's name.
Something like (Pseudocode):
int nameCount = 1;
fileName = file.Name;
while(fileName exists in archive)
{
nameCount++;
fileName = file.Name + "_" + nameCount;
}

Count the number of files with specific extension

:)
So I have a hw (I have to run project from console): I have to count the number of sub directories in specific directory (the user writes in this way " [path] [extension] [-r] ")
So if user writes the directory and doesn't write the extension, my program just counts the number of sub directories.
BUT if user writes the parameter, for example, .exe, .txt, .cs, I have to count the number of files with this specific extension in the specific directory and return this number.
Sooo, everything is good with the first part - my program works correctly and count the number of sub directories, recursively (if I write the parameter -r) or not (if I don't). The problem is with counting files with extension.
Here is my function for counting sub directories:
class Data
{
public string curDir = Directory.GetCurrentDirectory();
public string Extension = "";
public bool isRecursive;
}
public static int CountDir(Data data)
{
string[] dirs = Directory.GetDirectories(data.curDir);
int res = dirs.Length;
int resFiles = files.Length;
try
{
if (data.isRecursive)
{
foreach (string subdir in dirs)
{
Data d = new Data();
d.curDir = subdir;
d.Extension = data.Extension;
d.isRecursive = data.isRecursive;
res += CountDir(d);
}
}
}
catch (Exception ex)
{
Console.WriteLine($"Exception: {ex.Message}");
}
return res;
}
So I tried to do the similar thing in this method, but for files and I'm a bit confused:
string[] files = Directory.GetFiles(data.curDir);
int resFiles = files.Length;
foreach (string ext in files)
{
FileInfo fi = new FileInfo(ext);
if (data.Extension != "")
{
if (fi.Extension == data.Extension)
{
//res = 0;
//++res;
//what am I supposed to do here?..
}
}
}
I also wonder if I can do this in the same method (CountDir).
Thank you so much in advance!
Edit: I know about SearchOptions.AllDirectories method, but I don't know in advance which extension user will write
I would put the file count logic in its own method since the goal is to get the number of files for a specific directory rather than all sub-directories. Here's an example based on your sample code:
public static int countFiles(Data data)
{
string[] files = new string[0];
try
{
files = Directory.GetFiles(data.curDir, $"*{data.Extension}");
}
catch (Exception ex)
{
Console.WriteLine($"Exception: {ex.Message}");
}
return files.Length;
}

System.UnauthorizedAccessException when getting files

I've asked a very similar question before here. But that was about getting directories, and this is about files. And these codes are a bit different from each other. Ever since I've been trying to convert this to make it look like the answer on my old question, I haven't been able to make it work.
string[] files = Directory.GetFiles(ScanPath, "*.*", System.IO.SearchOption.AllDirectories);
DateTime From = DateTime.Now.AddHours(-24);
DateTime To = DateTime.Now;
foreach (string name in files)
{
FileInfo file = new FileInfo(name);
string fullname = file.FullName;
if (file.LastWriteTime >= From & file.LastWriteTime <= To && file.Length >= ScanSize)
Console.WriteLine(file.FullName + " ; " + "last changed at " + " ; " + file.LastWriteTime.ToString());
}
I've been getting the same errors as I explained in the other question. Because I don't know where to put the code of the foreach in a recursion. Since it's not an enumeration but a Directory.GetFiles().
The error occurs with:
Directory.GetFiles(ScanPath, "*", SearchOption.AllDirectories);
because this gets all the files of the directories at once. But if I remove it, it only gets the files in the given path, without any of the files in the subdirectories. So I was told to apply recursion.
I am the administrator of the system and I plan to run this on the entire data drive. D:\
I'm hoping anyone here knows a good example.
Your app could not have access rights to some folders, for others you can use the following code:
void DiscoverDirs(string where, List<string> files, Func<FileInfo, bool> filter)
{
try
{
var di = new DirectoryInfo(where);
files.AddRange(di.EnumerateFiles().Where(filter).Select(x => x.FullName));
foreach (var dir in Directory.GetDirectories(where))
{
DiscoverDirs(dir, files, filter);
}
}
catch
{
// no access fo this dir, ignore
}
}
Usage:
DateTime From = DateTime.Now.AddHours(-24);
DateTime To = DateTime.Now;
var ScanSize = 5*1024*1024;
var list = new List<string>();
DiscoverDirs(#"C:\", list,
file => file.LastWriteTime >= From & file.LastWriteTime <= To && file.Length >= ScanSize);
foreach (string name in list)
{
FileInfo file = new FileInfo(name);
string fullname = file.FullName;
Console.WriteLine(file.FullName + " ; " + "last changed at " + " ; " + file.LastWriteTime.ToString());
}
You might be getting "UnauthorizedAccessException" while accessing the some of the system directories.List of the directory causing the problems are directories which are actually just redirection to other directory.
May be you can tried out the following code if it helps-
try
{
foreach (String file in Directory.GetFiles(directoryName, pattern, SearchOption.TopDirectoryOnly))
{
// do stuff
}
catch (UnauthorizedAccessException uae)
{
//handle
}
catch (Exception e)
{
//handle
}
Alternative:
string[] directories = Directory.GetDirectories(ScanPath);
foreach (string directory in directories)
{
string[] filesinCurrentDirectory = Directory.GetFiles(directory, "*.*", System.IO.SearchOption.AllDirectories);
foreach (string file in filesinCurrentDirectory)
{
MessageBox.Show(file);
}
}

Error while handling multiple txt files

I'm constructing a program to search all .xml inside a folder setted by user (Source folder) and copy all these files to another folder (Destination folder).
My program is able to search all XML within all sub folders from (Source folder), the result returns around 5000 files that are placed on a list, this list is worked later by a function, but he can only work with 31 files, then appears "not responding "and the debugger shows that the program is staying a long time in the execution.
Here is my code:
Button action:
private void btnCopiarSalvar_Click(object sender, EventArgs e)
{
foreach (string name in listFileNames)
{
if (readXML(name ))
{
tbArquivo.Text = name ; //Feedback textbox, tell the current filename
}
}
pbStatus.Increment(50);
cbFinal.Checked = true; //Feedback checkBox, to tell user that the task is over.
}
Function ReadXML
public bool readXML(string name)
{
//foreach (string nome in listaArquivos)
//{ //I tried to the foreach inside, but nothing Works.
try
{
string text = null;
string readBuffer = File.ReadAllText(name);
text = readBuffer.Aggregate(text, (current, b) => current + b);
var encoding = new ASCIIEncoding();
Byte[] textobytes = encoding.GetBytes(text);
if (!File.Exists(destino))
{
string destinoComNomeArquivo = destino + "\\" + Path.GetFileName(nome);
using (FileStream fs = File.Create(destinoComNomeArquivo))
{
foreach (byte textobyte in textobytes)
{
fs.WriteByte(textobyte);
pbProcess.PerformStep();
}
Console.WriteLine("Arquivo gravado " + Path.GetFileName(nome));
}
}
pbProcess.PerformStep();
}
catch (Exception e)
{
Console.WriteLine(e);
}
//}
return true;
}
Error: ContextSwitchDeadlock was detected.
Tried Solution: Disable Managed Debug Assistants.
After disabling the MDA, the programs still only read-copy 31 files (of 5k).
The first thing i recommand is ... don't do that kind of file copy! use the File.Copy function instead.
Try to use this code snipping from MSDN:
void DoCopy(string path)
{
var copytask = new Task(() =>
{
string destinoComNomeArquivo = #"C:\" + Path.GetFileName(path);
DirectoryCopy(path, destinoComNomeArquivo, false);
});
copytask.Start();
}
private void DirectoryCopy(string sourceDirName, string destDirName, bool copySubDirs)
{
DirectoryInfo dir = new DirectoryInfo(sourceDirName);
DirectoryInfo[] dirs = dir.GetDirectories();
if (!dir.Exists)
{
throw new DirectoryNotFoundException(
"Source directory does not exist or could not be found: "
+ sourceDirName);
}
if (!Directory.Exists(destDirName))
{
Directory.CreateDirectory(destDirName);
}
FileInfo[] files = dir.GetFiles();
foreach (FileInfo file in files)
{
string temppath = Path.Combine(destDirName, file.Name);
file.CopyTo(temppath, false);
}
var counter = 0;
var maxcounter = files.Count();
while (maxcounter < counter)
{
var item = files.ElementAt(counter).Name;
WriteAsnc(item);
counter++;
}
if (copySubDirs)
{
foreach (DirectoryInfo subdir in dirs)
{
string temppath = Path.Combine(destDirName, subdir.Name);
DirectoryCopy(subdir.FullName, temppath, copySubDirs);
}
}
}
const int _maxwritingprocess = Environment.ProcessorCount;
int _currentwritingtasks;
void WriteAsnc(string filepath)
{
_currentwritingtasks++;
var task = Task.Factory.StartNew(() =>
{
XDocument doc = XDocument.Load(filepath);
doc.Elements().First().Add(new XAttribute("Attribute Name","Attribute Value"));
doc.Save(filepath);
_currentwritingtasks--;
});
if(_currentwritingtasks == _maxwritingprocess)
task.Wait();
_currentwritingtasks--;
}
The next point the ContextSwitchDeadlock is a Threading problem and i thing your pbProcess is the source. What does that Process do i don't see anything of that process and i don't thing it is Impotent for your copy

extract ISO with winrar automatically with c# or batch

I'm trying to extract an ISO to a folder with the same name without .iso on the end.
I'm having a problem with winrar as it will not start the extract when I start up with the seach starting in the folder with the ISO.
UPDATED with answer code
private void ExtractISO(string toExtract, string folderName)
{
// reads the ISO
CDReader Reader = new CDReader(File.Open(toExtract, FileMode.Open), true);
// passes the root directory the folder name and the folder to extract
ExtractDirectory(Reader.Root, folderName /*+ Path.GetFileNameWithoutExtension(toExtract)*/ + "\\", "");
// clears reader and frees memory
Reader.Dispose();
}
private void ExtractDirectory(DiscDirectoryInfo Dinfo, string RootPath, string PathinISO)
{
if (!string.IsNullOrWhiteSpace(PathinISO))
{
PathinISO += "\\" + Dinfo.Name;
}
RootPath += "\\" + Dinfo.Name;
AppendDirectory(RootPath);
foreach (DiscDirectoryInfo dinfo in Dinfo.GetDirectories())
{
ExtractDirectory(dinfo, RootPath, PathinISO);
}
foreach (DiscFileInfo finfo in Dinfo.GetFiles())
{
using (Stream FileStr = finfo.OpenRead())
{
using (FileStream Fs = File.Create(RootPath + "\\" + finfo.Name)) // Here you can Set the BufferSize Also e.g. File.Create(RootPath + "\\" + finfo.Name, 4 * 1024)
{
FileStr.CopyTo(Fs, 4 * 1024); // Buffer Size is 4 * 1024 but you can modify it in your code as per your need
}
}
}
}
static void AppendDirectory(string path)
{
try
{
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
}
catch (DirectoryNotFoundException Ex)
{
AppendDirectory(Path.GetDirectoryName(path));
}
catch (PathTooLongException Ex)
{
AppendDirectory(Path.GetDirectoryName(path));
}
}
The user selects the folder to extract (.ISO) toExtract. I then use it in the Process.Start() in the background worker. That just seems to open the mounting software and doesn't extract the ISO to the desired folder name.
Thanks in advance for your help.
Or if anyone could give me a batch to extract the ISO instead and to call it from c# passing toExtract and the folder name that would be helpful too.
Thanks
If external Class Libraries are OK!
Then use SevenZipSharp or .NET DiscUtils to extract ISO's...
These two ClassLibraries can manage ISO and Extract them!
For DiscUtils you can find some codes for ISO Management [CDReader Class] at the Link I provided.
But For SevenZipSharp, Please Explore the ClassLibrary source and find the Code to Extract or Google to find it!
To get the Name of the folder just use Path.GetFileNameWithoutExtension((string)ISOFileName) which will return "ISOFile" for an iso named "ISOFile.iso". And then you can use it with your desired path.
UPDATE
Code To Extract ISO Image with DiscUtils :
using DiscUtils;
using DiscUtils.Iso9660;
void ExtractISO(string ISOName, string ExtractionPath)
{
using (FileStream ISOStream = File.Open(ISOName, FileMode.Open))
{
CDReader Reader = new CDReader(ISOStream, true, true);
ExtractDirectory(Reader.Root, ExtractionPath + Path.GetFileNameWithoutExtension(ISOName) + "\\", "");
Reader.Dispose();
}
}
void ExtractDirectory(DiscDirectoryInfo Dinfo, string RootPath, string PathinISO)
{
if (!string.IsNullOrWhiteSpace(PathinISO))
{
PathinISO += "\\" + Dinfo.Name;
}
RootPath += "\\" + Dinfo.Name;
AppendDirectory(RootPath);
foreach (DiscDirectoryInfo dinfo in Dinfo.GetDirectories())
{
ExtractDirectory(dinfo, RootPath, PathinISO);
}
foreach (DiscFileInfo finfo in Dinfo.GetFiles())
{
using (Stream FileStr = finfo.OpenRead())
{
using (FileStream Fs = File.Create(RootPath + "\\" + finfo.Name)) // Here you can Set the BufferSize Also e.g. File.Create(RootPath + "\\" + finfo.Name, 4 * 1024)
{
FileStr.CopyTo(Fs, 4 * 1024); // Buffer Size is 4 * 1024 but you can modify it in your code as per your need
}
}
}
}
static void AppendDirectory(string path)
{
try
{
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
}
catch (DirectoryNotFoundException Ex)
{
AppendDirectory(Path.GetDirectoryName(path));
}
catch (PathTooLongException Exx)
{
AppendDirectory(Path.GetDirectoryName(path));
}
}
Use It with Like This :
ExtractISO(ISOFileName, Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory) + "\\");
Working! Tested By Me!
And Of Course You can always add more Optimization to the code...
This Code is Just a Basic One!

it has extracted from a application source ISOReader but modified for my requirements
total source is available at http://www.java2s.com/Open-Source/CSharp_Free_CodeDownload/i/isoreader.zip
Try this:
string Desktop = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
Process.Start("Winrar.exe", string.Format("x {0} {1}",
Desktop + "\\test.rar",
Desktop + "\\SomeFolder"));
That would extract the file test.rar to the folder SomeFolder. You can change the .rar extention to .iso, it'll work the same.
As far as I can see in your current code, there is no command given to extract a file, and no path to the file that has to be extracted. Try this example and let me know if it works =]
P.S. If you'd like to hide the extracting screen, you can set the YourProcessInfo.WindowStyle to ProcessWindowStyle.Hidden.
I hace confrunted recently with this kind of .iso extraction issue. After trying several methods, 7zip did the job for me, you just have to make sure that the latest version of 7zip is installed on your system. Maybe it will help
