TextWriter not working because its being used by another process. Network 5.0

I am trying to create a console app on network version 5.0 using visual studio. The purpose is to read all the PNG files in a directory, and make a JSON file with the code:
{
"format_version": "1.16.100",
"minecraft:texture_set": {
"color": "*Filename*",
"metalness_emissive_roughness": "*Filename_mer*"
}
}
In it. And yes this is for Minecraft. The filename and the filename_mer are automatically filled in by code, but that isn't my issue.
static void Main(string[] args)
{
Console.WriteLine("Goto " + Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) + "\\Packages\\Microsoft.MinecraftUWP_8wekyb3d8bbwe\\LocalState\\games\\com.mojang\\resource_packs" + " And find the resource pack you want to generate files into");

This is all my code, on the file. It reads a directory which you enter, looks through the textures file, and for each PNG file in there it creates a JSON file with the code specified earlier. Although when run the code gives me this error.
System.IO.IOException: 'The process cannot access the file 'C:\Users\https\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\resource_packs\Vanilla_Resource_Pack_1.17.10\textures\blocks\acacia_trapdoor.texture_set.json' because it is being used by another process.'
I cannot find any answers which fit my issue, I would appreciate any help.
This is a Minecraft Bedrock edition resource pack btw, not sure if that helps.

Don't do this File.Create(newPath); or rethink your problem. It looks like a typo.
In short File.Create(newPath) is creating a FileStream and discarding it, leaving the file open and with a share lock. If you are trying to pre-create the file, at least use the using statement:
using (File.Create(newPath));
or Close
File.Create(newPath).Close();
or
File.WriteAllText(newPath, String.Empty);
or
File.WriteAllBytes(newPath, Array.Empty<byte>());
If you are just trying to create or overwrite the file StreamWriter(newPath, false) is good enough.

Can not delete the existing file in C#.net

I am trying to upload a file in asp.net. File may be image or pdf. If the file already exist then I have to remove existing file and upload the new file. But if I try to delete existing file, it shows an error that "The process cannot access the file because it is being used by another process"
This is the code for my file upload.
if (FileUploadFollowUpUN.HasFile)
{
if (Request.QueryString.Count > 0 && Request.QueryString["PCD"] != null)
{
filename = System.IO.Path.GetFileName(FileUploadFollowUpUN.FileName.Replace(FileUploadFollowUpUN.FileName, Request.QueryString["PCD"] + " " + "D" + Path.GetExtension(FileUploadFollowUpUN.FileName)));
SaveFilePath = Server.MapPath("~\\ECG\\") + filename;
DirectoryInfo oDirectoryInfo = new DirectoryInfo(Server.MapPath("~\\ECG\\"));
if (!oDirectoryInfo.Exists)
Directory.CreateDirectory(Server.MapPath("~\\ECG\\"));
if (File.Exists(SaveFilePath))
{
File.SetAttributes(SaveFilePath, FileAttributes.Normal);
File.Delete(SaveFilePath);
}
FileUploadFollowUpUN.SaveAs(Server.MapPath(this.UploadFolderPath) + filename);
Session["FileNameFollowUpUN"] = filename;
if (System.IO.Path.GetExtension(FileUploadFollowUpUN.FileName) == ".pdf")
{
imgPhoto.ImageUrl = "~/Images/pdf.jpg";
ZoomImage.ImageUrl = "~/Images/pdf.jpg";
imgPhoto.Enabled = true;
}
else
{
imgPhoto.ImageUrl = "~/ECG/" + filename;
imgPhoto.Enabled = true;
ZoomImage.ImageUrl = "~/ECG/" + filename;
}
}
}
How can I get rid out of this error?

There is a similar question here on how to find what process is using a file
You should try to dispose any file methods before trying to delete.
You could stick it in a while loop if you have something which will block until the file is accessible
public static bool IsFileReady(String sFilename)
{
// If the file can be opened for exclusive access it means that the file
// is no longer locked by another process.
try
{
using (FileStream inputStream = File.Open(sFilename, FileMode.Open, FileAccess.Read, FileShare.None))
{
if (inputStream.Length > 0)
{
return true;
}
else
{
return false;
}
}
}
catch (Exception)
{
return false;
}
}

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!

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;

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;
}

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
try
{
Process cmd = new Process();
cmd.StartInfo.FileName = "cmd.exe";
cmd.StartInfo.RedirectStandardInput = true;
cmd.StartInfo.RedirectStandardOutput = true;
cmd.StartInfo.CreateNoWindow = false;
cmd.StartInfo.UseShellExecute = false;
cmd.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
cmd.Start();
cmd.StandardInput.WriteLine("C:");
//Console.WriteLine(cmd.StandardOutput.Read());
cmd.StandardInput.Flush();
cmd.StandardInput.WriteLine("cd C:\\\"Program Files\"\\7-Zip\\");
//Console.WriteLine(cmd.StandardOutput.ReadToEnd());
cmd.StandardInput.Flush();
cmd.StandardInput.WriteLine(string.Format("7z x -y -o{0} {1}", source, copyISOLocation.TempIsoPath));
//Console.WriteLine(cmd.StandardOutput.ReadToEnd());
cmd.StandardInput.Flush();
cmd.StandardInput.Close();
cmd.WaitForExit();
Console.WriteLine(cmd.StandardOutput.ReadToEnd());

DotNetZip - reading to memory

I've put together a quick test using the DotNetZip library which opens a zip file full of .bmp files and converts them to .jpg format.
Prior to this I was writing all of the files to a folder, converting them, saving out the jpg files & then removing the original bmp files, which got messy.
I'm no looking to unzip them in memory first, convert to jpg & then save.
The code works, but just isn't that quick. Can anyone give me any pointers as to what I can do to improve the code please? Also, Would threading help?
string zipToUnpack = "c:\\test\\1000.zip";
string unpackDirectory = "c:\\temp\\";
string f = string.Empty;
Bitmap bm;
MemoryStream ms;
using (ZipFile zip = ZipFile.Read(zipToUnpack))
{
foreach (ZipEntry e in zip)
{
if (e.FileName.ToLower().IndexOf(".bmp") > 0)
{
ms = new MemoryStream();
e.Extract(ms);
try
{
bm = new Bitmap(ms);
f = unpackDirectory + e.FileName.ToLower().Replace(".bmp", ".jpg");
bm.Save(f, System.Drawing.Imaging.ImageFormat.Jpeg);
}
catch (Exception ex)
{
Console.WriteLine("File: " + e.FileName + " " + ex.ToString());
}
ms.Dispose();
}
}
}
Thanks

In general, DotNetZip is single-threaded. You can open multiple archives in multiple threads, but each archive in only one thread.
If you want to enlist multiple CPUs or cores, then I can suggest calling QueueUserWorkItem for the part where you convert the data in the MemoryStream into a jpg.
The call to ZipEntry.Extract() needs to be done on the same thread, for all entries. This is because the Zipfile maintains a single FileStream for all read access, and multiple threads extracting entries will cause file pointer arithmetic errors.
So, something like this:
public class State
{
public string FileName;
public MemoryStream stream;
}
public void Run()
{
string unpackDirectory = "c:\\temp\\";
string zipToUnpack = "c:\\test\\1000.zip";
var ConvertImage = new WaitCallback( (o) => {
State s = o as State;
try
{
var bm = new Bitmap(s.stream);
var f = unpackDirectory + s.FileName.ToLower().Replace(".bmp", ".jpg");
bm.Save(f, System.Drawing.Imaging.ImageFormat.Jpeg);
}
catch (Exception ex)
{
Console.WriteLine("File: " + s.FileName + " " + ex.ToString());
}
});
using (ZipFile zip = ZipFile.Read(zipToUnpack))
{
foreach (ZipEntry e in zip)
{
if (e.FileName.ToLower().IndexOf(".bmp") > 0)
{
var ms = new MemoryStream();
e.Extract(ms);
ThreadPool.QueueUserWorkItem ( ConvertImage,
new State {
FileName = e.FileName, stream = ms }
});
}
}
}
}

How to open file with its application(the file not exist in the web server)?

I want to ask how to open a specific file (the file is out of the server, i have a relative path to it stored in config file) with its application, when clicking on a specific link button or hyper link...
like :
opening
.docx with word.
or
.pdf with acrobat reader
i tried several methods but , i get different errors like
Cannot use a leading .. to exit above the top directory
my .cs:
public void ProcessRequest(HttpContext context)
{
int newsId = int.Parse(context.Session["newsId"].ToString());
int FK_UnitId = int.Parse(context.Session["UserData"].ToString());
string dirPathForTextFiles = ConfigurationManager.AppSettings.GetValues("ThePath").First() + "/" + "NewsTextFiles" + "/" + "UnitNum" + FK_UnitId.ToString() + "_" + "NewsNum" + newsId + "/";
DataTable UpdatedDateTable = (DataTable)context.Session["theLastUpdatedTextFile"];
UpdatedDateTable.AcceptChanges();
context.Session.Add("currentTextFile", UpdatedDateTable);
List<string> l = new List<string>(UpdatedDateTable.Rows.Count);
try
{
l.Add(dirPathForTextFiles + UpdatedDateTable.Rows[0]["fileName"].ToString());
context.Response.ContentType = getContentType(dirPathForTextFiles + UpdatedDateTable.Rows[0]["fileName"].ToString());
System.Diagnostics.Process.Start(l[0]);
context.ClearError();
}
catch (IOException e)
{
string message = e.Message;
}
}
string getContentType(String path)
{
switch (Path.GetExtension(path))
{
case ".doc": return " application/msword";
case ".docx": return "application/msword";
case ".pdf": return "application/pdf";
default: break;
}
return "";
}

In order to get the full file path on the server you'll want to use Server.MapPath.
string fullFileName = Server.MapPath("../myFile.pdf");
Edit: After that you'll need the Process object to "run" it:
System.Diagnostics.Process.Start(fullFileName);
Edit 2: If you want the file to be opened on the client side, your best bet is to create and HTTP Handler and set the appropriate mime type on your response before streaming it out from your handler.
Edit 3: Code to stream a file out to client.
public void ProcessRequest(HttpContext context)
{
int newsId = int.Parse(context.Session["newsId"].ToString());
int FK_UnitId = int.Parse(context.Session["UserData"].ToString());
string dirPathForTextFiles = ConfigurationManager.AppSettings.GetValues("ThePath").First() + "/" + "NewsTextFiles" + "/" + "UnitNum" + FK_UnitId.ToString() + "_" + "NewsNum" + newsId + "/";
DataTable UpdatedDateTable = (DataTable)context.Session["theLastUpdatedTextFile"];
UpdatedDateTable.AcceptChanges();
context.Session.Add("currentTextFile", UpdatedDateTable);
List<string> l = new List<string>(UpdatedDateTable.Rows.Count);
try
{
l.Add(dirPathForTextFiles + UpdatedDateTable.Rows[0]["fileName"].ToString());
context.Response.ContentType = getContentType(dirPathForTextFiles + UpdatedDateTable.Rows[0]["fileName"].ToString());
using (FileStream fs = new FileStream(l[0], FileMode.Open, FileAccess.Read))
{
long chunkSize = fs.Length;
byte[] buf = new byte[chunkSize];
int bytesRead = 1;
bytesRead = fs.Read(buf, 0,(int)chunkSize);
if (bytesRead > 0) context.Response.OutputStream.Write(buf, 0, buf.Length);
context.Response.OutputStream.Flush();
}
}
catch (IOException e)
{
string message = e.Message;
}
}
