如何在 C# 中創建 Zip 存檔

How to Create Zip Files in C#

1. Create a Console Application in Visual Studio.
2. Install a C# Zip Library via NuGet Package Manager.
3. Set the Output Zip File Path by using the IronArchive class.
4. Add Files to Zip using Add() method.

IronZIP

IronZIP is a leading C# ZIP archive library designed for creating, reading, and extracting archives in .NET. It offers a user-friendly API that prioritizes accuracy, ease of use, and speed. The library supports various file formats, which includes the ZIP, TAR, GZIP, and BZIP2 archives. With cross-platform compatibility and support for multiple .NET versions, IronZIP is versatile and caters to a wide range of development environments, including web, mobile, desktop, and console applications.

Prerequisites

Before diving into the implementation, ensure you have the following prerequisites in place:

1. Visual Studio: Install Visual Studio, a comprehensive integrated development environment for building C# applications. If not installed, download it from its official website.
2. IronZIP Package: Use NuGet Package Manager to install the IronZIP library for your project.

Visual Studio Console Project Setup

1. Open Visual Studio and create a new Console Project.

2. Configure the project name and location.

   

3. Choose the appropriate .NET version based on your project requirements. The latest is recommended and is also supported by IronZIP.

Install IronZIP via NuGet

Integrating IronZIP into the project is straightforward through NuGet Package Manager. Follow these steps:

1. Open the Manage NuGet Packages for Solution by right-clicking the Solution Explorer.

2. In the NuGet browse tab, search for IronZIP and click install.

   

3. Alternatively, you can select NuGet Package Manager Console from the 'tools' menu. Then, in the console, you can run the following command to install IronZIP:

   Install-Package IronZip

Now, with IronZIP integrated into the project, let's proceed to create a zip archive.

How To (In C#) Create Zip Archive

In C#, specifically using IronZIP, the process of creating a zip archive is simplified. By initializing an IronArchive object, you can specify the name of the newly created zip file and then proceed to add files to it using the Add() method. This method takes file paths as parameters and allows for the inclusion of multiple files in the archive.

The compression level can also be customized based on the specific requirements of the application. For instance, specifying the compression level in the code allows developers to balance between file size reduction and the speed of compression.

Below is the sample code for creating a zip archive using IronZIP:

using IronZIP;

class Program
{
    public static void Main(string[] args)
    {
        // Create an empty ZIP archive
        using (var archive = new IronArchive("output.zip"))
        {
            // Add files to the ZIP archive
            archive.Add("./assets/image1.jpg");
            archive.Add("./assets/image2.jpg");
            archive.Add("./assets/image3.jpg");
        }
        // Inform the user that the ZIP file was created successfully
        Console.WriteLine("Zip file generated successfully!");
    }
}

using IronZIP;

class Program
{
    public static void Main(string[] args)
    {
        // Create an empty ZIP archive
        using (var archive = new IronArchive("output.zip"))
        {
            // Add files to the ZIP archive
            archive.Add("./assets/image1.jpg");
            archive.Add("./assets/image2.jpg");
            archive.Add("./assets/image3.jpg");
        }
        // Inform the user that the ZIP file was created successfully
        Console.WriteLine("Zip file generated successfully!");
    }
}

Imports IronZIP

Friend Class Program
	Public Shared Sub Main(ByVal args() As String)
		' Create an empty ZIP archive
		Using archive = New IronArchive("output.zip")
			' Add files to the ZIP archive
			archive.Add("./assets/image1.jpg")
			archive.Add("./assets/image2.jpg")
			archive.Add("./assets/image3.jpg")
		End Using
		' Inform the user that the ZIP file was created successfully
		Console.WriteLine("Zip file generated successfully!")
	End Sub
End Class

Output

After running the program, check the project's specified directory for the generated "output.zip" file containing all the files that were added. In this case, the specified image files. You have now stored your files effectively and efficiently, and you can access the original files through decompressing zip files.
