如何在 C# 中解壓縮 Zip 文件

Key Features

1. Easy-to-Use API: IronZIP provides a user-friendly API, allowing developers to perform common ZIP operations with simplicity.
2. Versatile Decompression Options: IronZIP supports various decompression options, including handling password-protected ZIP files, applying AES encryption, and specifying compression levels.
3. Cross-Platform Support: With IronZIP, developers can seamlessly decompress ZIP files on various platforms, ensuring compatibility across different environments.
4. .NET Integration: As a .NET-focused library, IronZIP integrates smoothly with C# projects, supporting different .NET versions and project types.

Step 1: Create a C# Console Project in Visual Studio

• Open Visual Studio and create a new C# console project.
  • Configure the project name and location.

• Choose the appropriate .NET Framework version based on your project requirements. IronZIP supports the latest version and older versions of .NET and .NET core, so you can choose any version from the available list.

Step 2: Install IronZIP using NuGet Package Manager

Integrating IronZIP into the project is straightforward:

• Open the Manage NuGet Packages for Solution by right-clicking the Solution Explorer.
  • In the NuGet browse tab, search for IronZIP and click install.

• Alternatively, you can use the NuGet Package Manager Console and run the following command:

  Install-Package IronZip

Now let's walk through the steps to decompress an existing ZIP file in a C# console application using IronZIP

Step 3: Import the Necessary Namespace

Add the following line of code at the top of the main source code file:

using IronZIP;

using IronZIP;

Imports IronZIP

Step 4: Open Zip Archive and Extract Files

To extract files from a ZIP, first we need to open ZIP archives or RAR files, which can be difficult sometimes in program applications. However, IronZIP with its single method makes this task easy and allows developers to handle it efficiently for the extraction process. Here is the code to open zip and unzip the selected file:

public static void Main(string[] args)
{
    // Specify the path to the ZIP file
    string zipFilePath = "existing.zip";

    // Specify the directory to extract to
    string extractDirectory = "extracted";

    // Call ExtractArchiveToDirectory method
    IronArchive.ExtractArchiveToDirectory(zipFilePath, extractDirectory);
    Console.WriteLine("ZIP file decompressed successfully!");
}

public static void Main(string[] args)
{
    // Specify the path to the ZIP file
    string zipFilePath = "existing.zip";

    // Specify the directory to extract to
    string extractDirectory = "extracted";

    // Call ExtractArchiveToDirectory method
    IronArchive.ExtractArchiveToDirectory(zipFilePath, extractDirectory);
    Console.WriteLine("ZIP file decompressed successfully!");
}

Public Shared Sub Main(ByVal args() As String)
	' Specify the path to the ZIP file
	Dim zipFilePath As String = "existing.zip"

	' Specify the directory to extract to
	Dim extractDirectory As String = "extracted"

	' Call ExtractArchiveToDirectory method
	IronArchive.ExtractArchiveToDirectory(zipFilePath, extractDirectory)
	Console.WriteLine("ZIP file decompressed successfully!")
End Sub

The above code example demonstrates a straightforward way to extract the contents of a ZIP file using IronZIP in C#.

Code Explanation:

• Specify ZIP File Path:

  • Use a string variable (zipFilePath) to store the path to the ZIP file you want to extract.
  • Example: string zipFilePath = "existing.zip";

• Specify Extraction Directory:

  • Use another string variable (extractDirectory) to specify the directory where you want to extract the ZIP file contents.
  • Example: string extractDirectory = "extracted";
• Call ExtractArchiveToDirectory Method:
  • Utilize IronZIP's ExtractArchiveToDirectory method to perform the extraction.
  • Pass the ZIP file path and extraction directory as parameters to the method.
  • Example: IronArchive.ExtractArchiveToDirectory(zipFilePath, extractDirectory);

To make it more simple, we can write a one-liner code as follows:

IronArchive.ExtractArchiveToDirectory("existing.zip", "extracted");

IronArchive.ExtractArchiveToDirectory("existing.zip", "extracted");

IronArchive.ExtractArchiveToDirectory("existing.zip", "extracted")
