To extract only specific files from a ZIP archive in C#, you can use the System.IO.Compression namespace, particularly ZipArchive and ZipArchiveEntry.

Example: Extract Specific Files from ZIP

using System.IO;
using System.IO.Compression;

public class ZipExtractor
{
    public static void ExtractSelectedFiles(string zipPath, string extractPath, string[] filesToExtract)
    {
        using ZipArchive archive = ZipFile.OpenRead(zipPath);

        foreach (var entry in archive.Entries)
        {
            if (filesToExtract.Contains(entry.FullName))
            {
                string destination = Path.Combine(extractPath, entry.FullName);
                Directory.CreateDirectory(Path.GetDirectoryName(destination)!);
                entry.ExtractToFile(destination, overwrite: true);
            }
        }
    }
}

Usage

string zipFile = "path/to/archive.zip";
string outputDir = "path/to/output";
string[] filesToExtract = new[]
{
    "documents/readme.txt",
    "images/logo.png"
};

ZipExtractor.ExtractSelectedFiles(zipFile, outputDir, filesToExtract);

Notes

  • entry.FullName includes any subdirectory path inside the ZIP.
  • Be sure the names in filesToExtract match the exact path within the ZIP (case-sensitive on some systems).
  • You can filter with entry.Name if you only care about file names, regardless of folder structure.
