如何在 C# .NET Core 中创建 ZIP 文件

How to Create ZIP Files C# using .NET Core

1. Launch a fresh ASP.NET Core project.
2. To the generated project, install the IronZIP library.
3. Using the IronArchive class, instantiate a blank ZIP file.
4. To add files to the empty ZIP file, use the Add method.
5. You may use the FromFile method to open an existing ZIP file.

IronZIP Library

The .NET library IronZIP, developed by Iron Software, simplifies the handling and management of ZIP files in .NET applications. It provides programmers with capabilities and tools to enable them to work with ZIP archives in several ways.

These include creating, removing, compressing data, opening, decrypting, and editing the files and folders contained within ZIP files.

Creating a New Project in Visual Studio

Select File from the File menu after launching the Visual Studio program. After choosing "new project," choose ".NET Core console application."

Enter the project name in the designated text field after choosing the file location. Next, as seen in the sample below, click the Create button and choose the required .NET Framework.

The Visual Studio project will then construct its structure based on the selected application after that. If you want to create or execute the application via the console, Windows, or web application, you may add code by gaining access to the Program.cs file.

After that, the code may be tested and the library added.

Install-Package IronZip

Create a Zip file using IronZIP

To use IronZIP to produce a ZIP archive file in C#, you must add files or directories to an archive before saving it. An example of using IronZIP to produce a ZIP file can be found below.

using IronZip;

class Program
{
    static void Main()
    {
        // Create an instance of IronZipArchive which provides methods to add files 
        // and save the archive
        using (var archive = new IronZipArchive())
        {
            // Add files to the archive by providing the path
            archive.Add("1.png");
            archive.Add("2.png");

            // Save the archive as a ZIP file
            archive.SaveAs("new.zip");
        }
    }
}

using IronZip;

class Program
{
    static void Main()
    {
        // Create an instance of IronZipArchive which provides methods to add files 
        // and save the archive
        using (var archive = new IronZipArchive())
        {
            // Add files to the archive by providing the path
            archive.Add("1.png");
            archive.Add("2.png");

            // Save the archive as a ZIP file
            archive.SaveAs("new.zip");
        }
    }
}

Imports IronZip

Friend Class Program
	Shared Sub Main()
		' Create an instance of IronZipArchive which provides methods to add files 
		' and save the archive
		Using archive = New IronZipArchive()
			' Add files to the archive by providing the path
			archive.Add("1.png")
			archive.Add("2.png")

			' Save the archive as a ZIP file
			archive.SaveAs("new.zip")
		End Using
	End Sub
End Class

In the code above, we first create an object for IronZipArchive which will allow us to use the Add method to add files to the archive. You can pass file paths as parameters to this method to include files in the ZIP.

We then use the SaveAs method to save the new ZIP file to the file system in the specified directory. It consolidates all the added files into a single ZIP file.

Conclusion

IronZIP is a .NET library created especially for managing ZIP files in C# applications. It allows developers to manage the compression, extraction, and modification of ZIP files.

IronZIP uses a clear API to simplify complex processes and make file operations easier, such as extracting specific files, extracting files in bulk, adding entries, and altering existing archives.

Developers may enhance file management capabilities in C# projects without having to start from scratch by using this package. It fits in with ease. Because of its flexibility, files may be added, modified, and removed from ZIP files dynamically to meet the needs of different applications.

IronZIP's robust exception-handling tools provide a consistent workflow and facilitate error correction in scenarios such as missing or damaged ZIP files.

While my memory may not match the latest updates, IronZIP provided a reliable option for handling ZIP files in .NET settings in the past.

IronZIP offers a free trial, with pricing starting from $799.
