The version numbering of this package itself and the version of SharpZipLib used in the package may look similar, but they are not related.

How to Use

• All SharpZipLib APIs are available under Unity.SharpZipLib namespace. For example:

    using System.IO;
    using Unity.SharpZipLib.GZip;
  
    ...
  
    public void Foo() {
        MemoryStream ms = new MemoryStream();
        GZipOutputStream outStream = new GZipOutputStream(ms);
        ...
    }
  
  

  Please refer to the API documentation of the SharpZipLib version used in this package for more details.

• In addition, com.unity.sharp-zip-lib also provides additional utility APIs:

  • ZipUtility.CompressFolderToZip(): Compresses the files in the nominated folder, and creates a zip file on disk.
  • ZipUtility.UncompressFromZip(): Uncompress the contents of a zip file into the specified folder.

  As an example:

  
  [Test]
  public void Foo() {
      //Compress 
      string tempZipPath = FileUtil.GetUniqueTempPathInProject();
      string folderToCompress ="Bar";
      ZipUtility.CompressFolderToZip(tempZipPath,null, folderToCompress);
  
      //Uncompress
      string tempExtractPath = FileUtil.GetUniqueTempPathInProject();
      Directory.CreateDirectory(tempExtractPath);
      ZipUtility.UncompressFromZip(tempZipPath, null, tempExtractPath);
  
  }
