Example Code

Here's an example code snippet that demonstrates how to use C1ZipFile to create a new zip file and add an entry to it:

using ComponentOne.Zip;

class Program
{
    static void Main(string[] args)
    {
        // Create a new instance of C1ZipFile
        C1ZipFile zipFile = new C1ZipFile("example.zip");

        // Create a new entry
        C1ZipEntry entry = new C1ZipEntry("example.txt");

        // Add the entry to the zip file
        zipFile.Entries.Add(entry);

        // Save the zip file
        zipFile.Save();
    }
}

Conclusion

In conclusion, C1ZipFile is a powerful tool for compressing and manipulating data in .NET applications. With its robust features and ease of use, C1ZipFile makes it easy to optimize storage and network bandwidth, and to work with compressed data efficiently.
