Zip .NET API for Files Compression & Archiving

Single file compression - C#

  var dir = "Path/To/Directory/";
  using (var arch = new Archive())
  {
      arch.CreateEntry("filename.dat", dir + "file.dat");
      arch.Save(dir + "result.zip");
  }

This code creates a ZIP archive named "result.zip" and adds a single file to it. Here’s a description of what it does:

• Directory Path : It defines a variable named dir and assigns a string containing the full directory path where the files reside.
• Creating the Archive : The code utilizes a using construct, ensuring correct resource management by automatically releasing the archive object (arch) after the code within the block finishes executing.
• Adding File to Archive : Inside the using block, the code creates an entry in the archive with the name "filename.dat". The CreateEntry method takes two arguments:
  - The first argument specifies the name for the entry within the archive, "filename.dat".
  - The second argument provides the path to the actual file that will be added ("dir + file.dat"). This path combines the directory path stored in dir with the filename "file.dat".
  Since compression method was not specified, the file will be compressed with the default Deflate algorithm.
• Saving the Archive : Finally, the code calls the Save method on the archive object (arch). This composes the newly created ZIP archive with the added file to a file named "result.zip" within the same directory specified by dir.
