ZIP files serve as a convenient way to bundle multiple files and directories into a single archive. Whether you’re managing backups, distributing software, or sharing files, efficient extraction from ZIP archives is crucial. IronZIP, a powerful .NET library, simplifies this process by providing simple methods.

How to Zip Archive Extract To Directory in C#

  1. Install the IronZIP library in your project.
  2. Use the ExtractArchiveToDirectory() method provided by IronZIP.
  3. Specify the path to your ZIP file (e.g., "output.zip") and the target extraction directory (e.g., "extracted").

IronZIP empowers developers with a reliable and efficient solution whether you’re zipping up files for distribution, managing backups, or handling data archives.

Extracting a ZIP Archive to a Directory

Before we start, we need to install the IronZIP Library in our Project. We can add it by using NuGet Package Manager Console with the following command:

Install-Package IronZip

The above command will install the IronZIP Library along with the required dependencies in our project.

Alternatively, you may also download it from NuGet Package Manager for Solution by Browsing "IronZip".

Include the necessary using directives in your code:

using IronZip;
using IronZip.Enum;
using IronZip;
using IronZip.Enum;
Imports IronZip
Imports IronZip.Enum
VB   C#

Extract the ZIP file to the Specified directory

IronZIP simplifies the process of extracting a zip archive to a directory. We can extract files using just 1 line of code. The following code will extract all the files in the provided path.

internal class Program
 { 
static void Main(string [] args)
 {
     IronZipArchive.ExtractArchiveToDirectory("Contracts.zip", "Contracts");
 }
}
internal class Program
 { 
static void Main(string [] args)
 {
     IronZipArchive.ExtractArchiveToDirectory("Contracts.zip", "Contracts");
 }
}
Friend Class Program
Shared Sub Main(ByVal args() As String)
	 IronZipArchive.ExtractArchiveToDirectory("Contracts.zip", "Contracts")
End Sub
End Class
VB   C#

The above line of code extracts the contents of the “Contracts.zip” file and places them in a destination folder named “Contracts.” It’s a convenient way to handle ZIP archives programmatically in C# applications.

Explanation

  1. IronZipArchive: This is a class or object from the IronZIP library. It provides methods and properties for working with ZIP files.
  2. .ExtractArchiveToDirectory("Contracts.zip", "Contracts"):
    1. The method ExtractArchiveToDirectory is called on an instance of IronZipArchive
    2. The first argument, "Contracts.zip", represents the path to the ZIP file you want to extract.
  3. The second argument, "Contracts", specifies the target directory where the extracted files will be placed.

If the files already exist in a specified directory, it will overwrite existing files. The extracted file is as:

Extract Password-Protected ZIP Archive

IronZIP also provides a method to extract password-protected compressed files. The following example will extract the files from a password-protected ZIP file.

IronZipArchive.ExtractArchiveToDirectory("PasswordProtectedContracts.zip", "Contracts", "Pa55w0r2Zip");
IronZipArchive.ExtractArchiveToDirectory("PasswordProtectedContracts.zip", "Contracts", "Pa55w0r2Zip");
IronZipArchive.ExtractArchiveToDirectory("PasswordProtectedContracts.zip", "Contracts", "Pa55w0r2Zip")
VB   C#

The above code extracts the contents of a password-protected ZIP file named “PasswordProtectedContracts.zip” and places them in a directory called “Contracts.” The specified password ensures secure extraction of the protected ZIP file.

Access Existing Archive

IronZIP allows access to existing ZIP files without extracting them from a specified directory. This functionality is important for scenarios such as extracting files from compressed archives, validating the existence of specific entries, or even dynamically inspecting the contents of ZIP files in response to user interactions.

View Entries of the ZIP Archive

The following code example will access the existing ZIP file, and print its entries to the console.

using (var zipArchive = new IronZipArchive("Contracts.zip")) // ziparchive archive
 {
     // Get Entries list
     List<string> names = zipArchive.GetArchiveEntryNames(); 
     foreach (string name in names)
     {
         Console.WriteLine(name); //// method creates ziparchiveentry entry
     }
 }
using (var zipArchive = new IronZipArchive("Contracts.zip")) // ziparchive archive
 {
     // Get Entries list
     List<string> names = zipArchive.GetArchiveEntryNames(); 
     foreach (string name in names)
     {
         Console.WriteLine(name); //// method creates ziparchiveentry entry
     }
 }
Using zipArchive = New IronZipArchive("Contracts.zip") ' ziparchive archive
	 ' Get Entries list
	 Dim names As List(Of String) = zipArchive.GetArchiveEntryNames()
	 For Each name As String In names
		 Console.WriteLine(name) '// method creates ziparchiveentry entry
	 Next name
End Using
VB   C#

The above code uses the IronZIP to check out what's inside a ZIP file named "Contracts.zip." It creates an IronZipArchive object to grab a list of entry names (like file names) from the archive using the GetArchiveEntryNames method. If the ZIP file is password-protected, you can include the password when making the IronZipArchive object. The code then prints out each file name to the console.

This way, we can work with specified entries within a compressed archive.

The output is as follows:

Check if Specified Entry Exists in ZIP File

We can also check if the specified entry exists in the specified ZIP file. The following code shows the demonstration.

using (var zipArchive = new IronZipArchive("Contracts.zip"))
 {
     if(zipArchive.CheckArchiveEntryExist("Contract1.pdf"))
     {
         Console.WriteLine("File Exist");
     }
 }
using (var zipArchive = new IronZipArchive("Contracts.zip"))
 {
     if(zipArchive.CheckArchiveEntryExist("Contract1.pdf"))
     {
         Console.WriteLine("File Exist");
     }
 }
Using zipArchive = New IronZipArchive("Contracts.zip")
	 If zipArchive.CheckArchiveEntryExist("Contract1.pdf") Then
		 Console.WriteLine("File Exist")
	 End If
End Using
VB   C#

The above code uses the IronZIP library to check if a file named "Contracts.zip" contains an entry named "Contract1.pdf." It does this by creating an IronZipArchive object for the ZIP file. Inside the code block, there's an "if" statement checking if "Contract1.pdf" exists in the ZIP file. If it does, it prints "File Exist" to the console. In simpler terms, this code helps you confirm if a specific file is inside a ZIP file, and if it is, it lets you know.

Delete Entry from Existing ZIP File

IronZIP provides a method to delete entries from a ZIP file. The following code will delete a file from an existing ZIP.

using (var zipArchive = new IronZipArchive("Contracts.zip"))
{
    zipArchive.DeleteArchiveEntry("Contract1.pdf");
}
using (var zipArchive = new IronZipArchive("Contracts.zip"))
{
    zipArchive.DeleteArchiveEntry("Contract1.pdf");
}
Using zipArchive = New IronZipArchive("Contracts.zip")
	zipArchive.DeleteArchiveEntry("Contract1.pdf")
End Using
VB   C#

The above code demonstrates how to use IronZIP to delete an entry from a ZIP archive named “Contracts.zip.” Within the using block, the specified file named “Contract1.pdf” is removed from the archive. This operation ensures efficient management of ZIP files in C# applications.

Conclusion

In conclusion, IronZIP emerges as a valuable tool for C# developers, simplifying the handling of ZIP files in various scenarios. Whether it's extracting files for business use.
