WebThis class represents a Zip archive. You can ask for the contained entries, or get an input stream for a file entry. The entry is automatically decompressed. You can also update the archive adding or deleting entries. This class is thread safe for input: You can open input streams for arbitrary entries in different threads. WebThis would write the current state of the ZipArchive to disk, which means that calling Dispose () right after FlushAsync () would not block. Example usage: using ( var archive = await ZipFile. OpenAsync (" archive. zip ", ZipArchiveMode. Update )) { archive. CreateEntry (" empty. txt "); await archive. FlushAsync (); } Add DisposeAsync ().
