In my project, I want to add several folders containing different files to Project-Properties-Resources, but I found that I could't add folders to resources, which is the way I really need.
So, is there any possible way that I can add folders to Project-Properties-Resources? In visual studio, I only found Add Existing File, Add New String and so on.
Thanks in advance to anyone who read my question.
You compress the folders into ZIP files, add the file, then decompress at runtime.
using System.IO.Compression....
string startPath = #"c:\example\start";//folder to add
string zipPath = #"c:\example\result.zip";
ZipFile.CreateFromDirectory(startPath, zipPath, CompressionLevel.Fastest, true);
//add the ZIP file you just created to your resources
//Then, on startup, extract the zip to a folder you control
string extractPath = #"c:\example\extract";
ZipFile.ExtractToDirectory(zipPath, extractPath);
To do this once per update, do something like create a setting for delete, set it to true on distribution, then:
private void shouldExtract()
{
if (MyProject.Properties.Settings.Default.DeleteExtractionFolder == true)
{
if (Directory.Exists(myExtractionDirectory))
{
Directory.Delete(myExtractionDirectory);
//unzip
MyProject.Properties.Settings.Default.DeleteExtractionFolder = false;
}
}
}

I'm looking to make a program to make my life easier, I need to be able to easily select a folder, which I can do, I don't need help with that. I want to take the directory of a folder, and put that folder into a new folder with a specified name, and then zip up that folder into a zip format in which I can change the name and filetype of. Is this possible in vanilla C#? I've only ever done files for text and I've never looked at moving and packaging files. SO I'm really clueless, I'd just like to be guided into the right direction.
Edit: I found this code online, but I need to put the folder inside another folder, may I adapt upon this to do so?
string startPath = #"c:\example\start";
string zipPath = #"c:\example\result.zip";
string extractPath = #"c:\example\extract";
ZipFile.CreateFromDirectory(startPath, zipPath);
ZipFile.ExtractToDirectory(zipPath, extractPath);
So, after an extended chat discussion, here's what we've established.
The goal is to put the contents of a source directory into a zip with the following structure:
- Payload
|- name of source
|-- contents of source
Okay, so, starting from an input path called startPath:
var parent = Path.GetDirectoryName(startPath);
var payload = Path.Combine(parent, "payload");
Directory.CreateDirectory(payload); // ensure payload ex
Directory.Move(startPath, Path.Combine(payload, Path.GetFileName(startPath));
var zipPath = Path.Combine(parent, "export.zip");
File.Delete(zipPath);
ZipFile.CreateFromDirectory(payload , zipPath, CompressionLevel.Optimal, true);
The key is that true in the CreateFromDirectory call, that puts the entries in the archive under a directory with the same name as the directory being zipped (in this case, "payload"). Feel free to change CompressionLevel to other values if you want.
Now, this has the side effect of actually physically moving the source directory, which might not be the best user experience. If you want to avoid that, you'll have to basically do what ZipFile.CreateFromDirectory does by hand, which is to enumerate the source directory yourself and then copy the files into the zip archive (in which case you can name those files whatever you want):
var parent = Path.GetDirectoryName(startPath);
var zipPath = Path.Combine(parent, "export.zip");
File.Delete(zipPath);
using var zip = ZipFile.Open(zipPath, ZipArchiveMode.Create);
foreach(var file in Directory.EnumerateFiles(startPath, "*", SearchOption.AllDirectories))
{
// get the path of the file relative to the parent directory
// this gives us a path that starts with the source directory name
// e.g. C:\example\start\file.txt -> start\file.txt
var relativePath = Path.GetRelativePath(parent, file);
// construct the path of the entry in the archive
// this is "Payload", and then the relative path of the file
// we need to fix up the separators because zip entries use /
// e.g. start\file.txt -> Payload/start/file.txt
var entryPath = Path.Combine("Payload", relativePath).Replace(Path.DirectorySeparatorChar, '/');
// put the file in the archive
// to specify a compression level, pass it as the third parameter here
zip.CreateEntryFromFile(file, entryPath);
}
I saved some batch file as a resource on my application.
I want to access this file on run time - so I trying to file this file on the Resource folder but I get an exception that the
"resource folder is not there"
I trying to find the resource file by this code
var allBatchFiles = Directory.GetFiles( string.Format( #"..\..\Resources\" ) );
So how to make this work ?
Note that, when you run your application in Visual Studio, it is executed from the bin subfolder, which changes relative paths.
However, if you want to embed the batch file into your application, you are entirely on the wrong track. The resource is compiled into your EXE, and you need to use a different method to retrieve it. The following MSDN article gives an example on how this can be done:
How to embed and access resources by using Visual C#
There are at least two types of resources you might be referring to.
First, if you are referring to a RESX file, then usually you can access resources directly. So if you have a RESX file called "MyRes.resx" with a resource in it called "MyString" then you can use:
string contents = Resources.MyRes.MyString;
If you are adding files to the solution and marking them as Embedded Resources, then you can use Assembly.GetManifestResourceStream to access the data. Here's the utility functions I use:
public static Stream GetResourceStream(string pathName, string resName, Assembly srcAssembly = null)
{
if (srcAssembly == null) srcAssembly = Assembly.GetCallingAssembly();
var allNames = srcAssembly.GetManifestResourceNames();
return srcAssembly.GetManifestResourceStream(pathName + "." + resName);
}
public static string GetResourceString(string pathName, string resName, Assembly srcAssembly = null)
{
if (srcAssembly == null) srcAssembly = Assembly.GetCallingAssembly();
StreamReader sr = new StreamReader(GetResourceStream(pathName, resName, srcAssembly));
string s = sr.ReadToEnd();
sr.Close();
return s;
}
The pathName is a bit tricky - it's the name of the project plus any folder names in your project. So if you have a project "MyApp" with a folder called "MyResources" with a file called "Batch.txt" marked as a resource, then you would access the contents with:
string contents = GetResourceString("MyApp.MyResources", "Batch.txt");
I have an exe that already creates a csv file. If I save the exe in C:/EXE, then the cvs file automatically gets created in C:/EXE folder.
C# code uses StreamWriter to accomplish this:
using (TextWriter log = new StreamWriter(errorLog + errorBatchNumber.ToString("000") + ".csv", true))
{
if (errorCount == 0)
{
log.WriteLine("Error message");
}
log.WriteLine(link.StatusMessage);
log.Close();
}
What I need to add:
A folder needs to be created first where the csv file will be saved.
This folder will be created where the EXE was saved, in this example: C:/EXE
After folder and cvs file was created, it needs to be zipped thru code. (But I need to accomplish first 1 and 2)
Any ideas?
Thanks in advance guys! :)
If you know the path where the EXE will be saved then
Directory.CreateDirectory(path + folderName) to create folder
To zip items use SharpZipLib at
http://www.icsharpcode.net/opensource/sharpziplib/ or http://wiki.sharpdevelop.net/SharpZipLib_MainPage.ashx
Would be something like
DirectoryInfo di = new DirectoryInfo(#"C:\exe");
if(!di.Exists)
di.Create();
Then you can use di.FullName to get the directory to save your file into.
Syntax might be a bit off but it should be enough to get you started. You can check out the MSDN on DirectoryInfo as well.
What is an example (simple code) of how to zip a folder in C#?
Update:
I do not see namespace ICSharpCode. I downloaded ICSharpCode.SharpZipLib.dll but I do not know where to copy that DLL file. What do I need to do to see this namespace?
And do you have link for that MSDN example for compress folder, because I read all MSDN but I couldn't find anything.
OK, but I need next information.
Where should I copy ICSharpCode.SharpZipLib.dll to see that namespace in Visual Studio?
This answer changes with .NET 4.5. Creating a zip file becomes incredibly easy. No third-party libraries will be required.
string startPath = #"c:\example\start";
string zipPath = #"c:\example\result.zip";
string extractPath = #"c:\example\extract";
ZipFile.CreateFromDirectory(startPath, zipPath);
ZipFile.ExtractToDirectory(zipPath, extractPath);
From the DotNetZip help file, http://dotnetzip.codeplex.com/releases/
using (ZipFile zip = new ZipFile())
{
zip.UseUnicodeAsNecessary= true; // utf-8
zip.AddDirectory(#"MyDocuments\ProjectX");
zip.Comment = "This zip was created at " + System.DateTime.Now.ToString("G") ;
zip.Save(pathToSaveZipFile);
}
There's nothing in the BCL to do this for you, but there are two great libraries for .NET which do support the functionality.
SharpZipLib
DotNetZip
I've used both and can say that the two are very complete and have well-designed APIs, so it's mainly a matter of personal preference.
I'm not sure whether they explicitly support adding Folders rather than just individual files to zip files, but it should be quite easy to create something that recursively iterated over a directory and its sub-directories using the DirectoryInfo and FileInfo classes.
In .NET 4.5 the ZipFile.CreateFromDirectory(startPath, zipPath); method does not cover a scenario where you wish to zip a number of files and sub-folders without having to put them within a folder. This is valid when you wish the unzip to put the files directly within the current folder.
This code worked for me:
public static class FileExtensions
{
public static IEnumerable<FileSystemInfo> AllFilesAndFolders(this DirectoryInfo dir)
{
foreach (var f in dir.GetFiles())
yield return f;
foreach (var d in dir.GetDirectories())
{
yield return d;
foreach (var o in AllFilesAndFolders(d))
yield return o;
}
}
}
void Test()
{
DirectoryInfo from = new DirectoryInfo(#"C:\Test");
using (var zipToOpen = new FileStream(#"Test.zip", FileMode.Create))
{
using (var archive = new ZipArchive(zipToOpen, ZipArchiveMode.Create))
{
foreach (var file in from.AllFilesAndFolders().OfType<FileInfo>())
{
var relPath = file.FullName.Substring(from.FullName.Length+1);
ZipArchiveEntry readmeEntry = archive.CreateEntryFromFile(file.FullName, relPath);
}
}
}
}
Folders don't need to be "created" in the zip-archive. The second parameter "entryName" in CreateEntryFromFile should be a relative path, and when unpacking the zip-file the directories of the relative paths will be detected and created.
There is a ZipPackage class in the System.IO.Packaging namespace which is built into .NET 3, 3.5, and 4.0.
http://msdn.microsoft.com/en-us/library/system.io.packaging.zippackage.aspx
Here is an example how to use it.
http://www.codeproject.com/KB/files/ZipUnZipTool.aspx?display=Print
There's an article over on MSDN that has a sample application for zipping and unzipping files and folders purely in C#. I've been using some of the classes in that successfully for a long time. The code is released under the Microsoft Permissive License, if you need to know that sort of thing.
EDIT: Thanks to Cheeso for pointing out that I'm a bit behind the times. The MSDN example I pointed to is in fact using DotNetZip and is really very fully-featured these days. Based on my experience of a previous version of this I'd happily recommend it.
SharpZipLib is also quite a mature library and is highly rated by people, and is available under the GPL license. It really depends on your zipping needs and how you view the license terms for each of them.

using DotNetZip (available as nuget package):
public void Zip(string source, string destination)
{
using (ZipFile zip = new ZipFile

Usage:
Zip(#"c:\somefolder\subfolder\source", #"c:\somefolder2\subfolder2\dest");
Or
Zip(#"c:\somefolder\subfolder\source", #"c:\somefolder2\subfolder2\dest\output.zip");
Following code uses a third-party ZIP component from Rebex:
// add content of the local directory C:\Data\
// to the root directory in the ZIP archive
// (ZIP archive C:\archive.zip doesn't have to exist)
Rebex.IO.Compression.ZipArchive.Add(#"C:\archive.zip", #"C:\Data\*", "");
Or if you want to add more folders without need to open and close archive multiple times:
using Rebex.IO.Compression;
...
// open the ZIP archive from an existing file
ZipArchive zip = new ZipArchive(#"C:\archive.zip", ArchiveOpenMode.OpenOrCreate);
// add first folder
zip.Add(#"c:\first\folder\*","\first\folder");
// add second folder
zip.Add(#"c:\second\folder\*","\second\folder");
// close the archive
zip.Close(ArchiveSaveAction.Auto);
You can download the ZIP component here.
Using a free, LGPL licensed SharpZipLib is a common alternative.

You need to add the dll file as a reference in your project. Right click on References in the Solution Explorer->Add Reference->Browse and then select the dll.
Finally you'll need to add it as a using statement in whatever files you want to use it in.
ComponentPro ZIP can help you achieve that task. The following code snippet compress files and dirs in a folder. You can use wilcard mask as well.
using ComponentPro.Compression;
using ComponentPro.IO;
...
// Create a new instance.
Zip zip = new Zip();
// Create a new zip file.
zip.Create("test.zip");
zip.Add(#"D:\Temp\Abc"); // Add entire D:\Temp\Abc folder to the archive.
// Add all files and subdirectories from 'c:\test' to the archive.
zip.AddFiles(#"c:\test");
// Add all files and subdirectories from 'c:\my folder' to the archive.
zip.AddFiles(#"c:\my folder", "");
// Add all files and subdirectories from 'c:\my folder' to '22' folder within the archive.
zip.AddFiles(#"c:\my folder2", "22");
// Add all .dat files from 'c:\my folder' to '22' folder within the archive.
zip.AddFiles(#"c:\my folder2", "22", "*.dat");
// Or simply use this to add all .dat files from 'c:\my folder' to '22' folder within the archive.
zip.AddFiles(#"c:\my folder2\*.dat", "22");
// Add *.dat and *.exe files from 'c:\my folder' to '22' folder within the archive.
zip.AddFiles(#"c:\my folder2\*.dat;*.exe", "22");
TransferOptions opt = new TransferOptions();
// Donot add empty directories.
opt.CreateEmptyDirectories = false;
zip.AddFiles(#"c:\abc", "/", opt);
