How to extract the .img files using c# [duplicate]

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!

For UDF or for making Windows ISO Files after servicing(DISM) with out needs the above accepted answer is not working for me so i tried this working method with DiscUtils
using DiscUtils;
public static void ReadIsoFile(string sIsoFile, string sDestinationRootPath)
{
Stream streamIsoFile = null;
try
{
streamIsoFile = new FileStream(sIsoFile, FileMode.Open);
DiscUtils.FileSystemInfo[] fsia = FileSystemManager.DetectDefaultFileSystems(streamIsoFile);
if (fsia.Length < 1)
{
MessageBox.Show("No valid disc file system detected.");
}
else
{
DiscFileSystem dfs = fsia[0].Open(streamIsoFile);
ReadIsoFolder(dfs, #"", sDestinationRootPath);
return;
}
}
finally
{
if (streamIsoFile != null)
{
streamIsoFile.Close();
}
}
}
public static void ReadIsoFolder(DiscFileSystem cdReader, string sIsoPath, string sDestinationRootPath)
{
try
{
string[] saFiles = cdReader.GetFiles(sIsoPath);
foreach (string sFile in saFiles)
{
DiscFileInfo dfiIso = cdReader.GetFileInfo(sFile);
string sDestinationPath = Path.Combine(sDestinationRootPath, dfiIso.DirectoryName.Substring(0, dfiIso.DirectoryName.Length - 1));
if (!Directory.Exists(sDestinationPath))
{
Directory.CreateDirectory(sDestinationPath);
}
string sDestinationFile = Path.Combine(sDestinationPath, dfiIso.Name);
SparseStream streamIsoFile = cdReader.OpenFile(sFile, FileMode.Open);
FileStream fsDest = new FileStream(sDestinationFile, FileMode.Create);
byte[] baData = new byte[0x4000];
while (true)
{
int nReadCount = streamIsoFile.Read(baData, 0, baData.Length);
if (nReadCount < 1)
{
break;
}
else
{
fsDest.Write(baData, 0, nReadCount);
}
}
streamIsoFile.Close();
fsDest.Close();
}
string[] saDirectories = cdReader.GetDirectories(sIsoPath);
foreach (string sDirectory in saDirectories)
{
ReadIsoFolder(cdReader, sDirectory, sDestinationRootPath);
}
return;
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
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

cmd.WaitForExit();
Console.WriteLine(cmd.StandardOutput.ReadToEnd());

File lines not being replaced, even though I coded it to do so?

I'm trying to run through each line in a file which is a link. I then add to a string list all the dead links (links that return 404 or have a specific phrase printed on the page. It all works okay so far, but the only problem I currently face is it doesn't remove them from the file as I request near the end.
Why is this?
using System.Collections.Generic;
namespace dead_link_finder
{
using System;
using System.IO;
using System.Net;
using System.Threading;
static class Program
{
private static void Main(string[] args)
{
Console.ForegroundColor = ConsoleColor.White;
var fileToScan = Console.ReadLine();
var reader = new StreamReader(fileToScan);
string line;
var deadLinks = new List<string>();
while ((line = reader.ReadLine()) != null)
{
Log("Scanning: " + line, ConsoleColor.White);
using (var webClient = new WebClient())
{
try
{
var content = webClient.DownloadString(line);
if (content.Contains("text-danger"))
{
deadLinks.Add(line);
}
}
catch (WebException wex)
{
if (((HttpWebResponse)wex.Response).StatusCode == HttpStatusCode.NotFound)
{
deadLinks.Add(line);
}
}
}
}
reader.Close();
Console.WriteLine();
Console.WriteLine("Found: " + deadLinks.Count + " dead links in the collection.");
Console.WriteLine();
Thread.Sleep(5000);
Console.WriteLine("Removing the dead links, please wait...");
foreach (var deadLink in deadLinks)
{
var str = File.ReadAllText(fileToScan);
File.WriteAllText(fileToScan, str.Replace(deadLink, ""));
}
Console.WriteLine();
Console.WriteLine("Finished...");
Console.ReadKey(true);
}
}
}

You can try this. Parse the file contents into a list, save the dead links in another and then use the LINQ extension method Except() to get the difference.
This code is a bit messy and tries to do alot of things in one go. You should probably split it up into more manageable pieces like ReadFile(), CheckLinks() and WriteFile() or something.
using System.Collections.Generic;
using System;
using System.IO;
using System.Net;
using System.Threading;
using System.Linq;
namespace dead_link_finder

{
private static void Main(string[] args)

Console.ForegroundColor = ConsoleColor.White;
var fileToScan = Console.ReadLine();
var links = File.ReadAllLines(fileToScan);
var deadLinks = new List<string>();
var webClient = new WebClient();
foreach (var link in links)
{
try
{
var content = webClient.DownloadString(link);
if (content.Contains("text-danger"))
{
deadLinks.Add(link);
}
}
catch (WebException wex)
{
if (wex.Status == WebExceptionStatus.NameResolutionFailure )
{
deadLinks.Add(link);
}
}
}
Console.WriteLine();
Console.WriteLine("Found: " + deadLinks.Count + " dead links in the collection.");
Console.WriteLine();
Thread.Sleep(5000);
Console.WriteLine("Removing the dead links, please wait...");
var justTheGoodLinks = links.Except(deadLinks);
File.WriteAllLines(fileToScan, justTheGoodLinks);
Console.WriteLine();
Console.WriteLine("Finished...");
Console.ReadKey(true);
}
}
}

Backup Windows 7 with specific filetypes. Some folders unavilable

Im trying to backup a computer with Windows 7 installed.
In older systems I created a backup that found and copyied specific images and office files.
Now when trying in Windows 7, I face some problems regarding some folders that arent available for me like they used to be in older systems.
How can I tweek this problem. I really like this way of backing the system up prior to upgrading etc.
Thanks in advance.
Feel free to ask and comment.

How to write log file in c#?

How would I write a log file in c#?
Currently i have a timer with this statement which ticks every 20 secs:
File.WriteAllText(filePath+"log.txt", log);
For everything that i want logged i do this:
log += "stringToBeLogged";
As you can assume the string log just grows and grows as the program runs. (I don't even know if there is a maximum chars per string?)
I assume that there must be better ways of doing this. i just thought that it would be heavy to write the whole file again and again for every time something is added to the log.

From the performance point of view your solution is not optimal. Every time you add another log entry with +=, the whole string is copied to another place in memory. I would recommend using StringBuilder instead:
StringBuilder sb = new StringBuilder();
...
sb.Append("log something");
...
// flush every 20 seconds as you do it
File.AppendAllText(filePath+"log.txt", sb.ToString());
sb.Clear();
By the way your timer event is probably executed on another thread. So you may want to use a mutex when accessing your sb object.
Another thing to consider is what happens to the log entries that were added within the last 20 seconds of the execution. You probably want to flush your string to the file right before the app exits.

create a class create a object globally and call this
using System.IO;
using System.Reflection;
public class LogWriter
{
private string m_exePath = string.Empty;
public LogWriter(string logMessage)
{
LogWrite(logMessage);
}
public void LogWrite(string logMessage)
{
m_exePath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
try
{
using (StreamWriter w = File.AppendText(m_exePath + "\\" + "log.txt"))
{
Log(logMessage, w);
}
}
catch (Exception ex)
{
}
}
public void Log(string logMessage, TextWriter txtWriter)
{
try
{
txtWriter.Write("\r\nLog Entry : ");
txtWriter.WriteLine("{0} {1}", DateTime.Now.ToLongTimeString(),
DateTime.Now.ToLongDateString());
txtWriter.WriteLine(" :");
txtWriter.WriteLine(" :{0}", logMessage);
txtWriter.WriteLine("-------------------------------");
}
catch (Exception ex)
{
}
}
}

Use File.AppendAllText instead:
File.AppendAllText(filePath + "log.txt", log);

public static void WriteLog(string strLog)
{
StreamWriter log;
FileStream fileStream = null;
DirectoryInfo logDirInfo = null;
FileInfo logFileInfo;
string logFilePath = "C:\\Logs\\";
logFilePath = logFilePath + "Log-" + System.DateTime.Today.ToString("MM-dd-yyyy") + "." + "txt";
logFileInfo = new FileInfo(logFilePath);
logDirInfo = new DirectoryInfo(logFileInfo.DirectoryName);
if (!logDirInfo.Exists) logDirInfo.Create();
if (!logFileInfo.Exists)
{
fileStream = logFileInfo.Create();
}
else
{
fileStream = new FileStream(logFilePath, FileMode.Append);
}
log = new StreamWriter(fileStream);
log.WriteLine(strLog);
log.Close();
}
Refer Link:
blogspot.in

as posted by #randymohan, with using statements instead
public static void WriteLog(string strLog)
{
string logFilePath = #"C:\Logs\Log-" + System.DateTime.Today.ToString("MM-dd-yyyy") + "." + "txt";
FileInfo logFileInfo = new FileInfo(logFilePath);
DirectoryInfo logDirInfo = new DirectoryInfo(logFileInfo.DirectoryName);
if (!logDirInfo.Exists) logDirInfo.Create();
using (FileStream fileStream = new FileStream(logFilePath, FileMode.Append))
{
using (StreamWriter log = new StreamWriter(fileStream))
{
log.WriteLine(strLog);
}
}
}

Very convenient tool for logging is http://logging.apache.org/log4net/
You can also make something of themselves less (more) powerful. You can use http://msdn.microsoft.com/ru-ru/library/system.io.filestream (v = vs.110). Aspx

This is add new string in the file
using (var file = new StreamWriter(filePath + "log.txt", true))
{
file.WriteLine(log);
file.Close();
}

There are 2 easy ways
StreamWriter - http://www.dotnetperls.com/streamwriter
Log4Net like Log4j(Java) - http://www.codeproject.com/Articles/140911/log4net-Tutorial

If your application is multithreaded then in some environments file.appendalltext could give error like file already in use and if you skip that then you could lose important logs .
For that you can use
Lock object technique with file.append.. in that case it will wait for existing process to close and the write your log
This can also save you from adding other libraries in your source

Above code will throw: Process can't access the file because it is being used by another process error because of File.Create(m_exePath + "\" + "log.txt"); if you will comment out this it will work as expected
