解壓縮對于我們日常工作太經常用到了，畢竟它有諸多好處，比如節省空間、方便管理傳輸、保密作用等等。
而對于我們開發人員來說，項目開發也是經常需要用到，今天就給大家推薦用一個可以用于壓縮、解壓、解密，并支持多種壓縮類型和格式的開源項目。
項目簡介
這是一個純C#壓縮庫，用于.NET Standard 2.0、2.1、.NET Core 3.1和.NET 5.0，支持格式有zip/tar/bzip2/gzip/lzip，功能實現有解壓縮rar, 解壓縮7zip, 解壓縮zip, 解壓縮tar解壓縮bzip2, 解壓縮gzip, 解壓縮lzip。

protected void Write(CompressionType compressionType, string archive, string archiveToVerifyAgainst, Encoding encoding = null) {using (Stream stream = File.OpenWrite(Path.Combine(SCRATCH2_FILES_PATH, archive))) { WriterOptions writerOptions = new WriterOptions(compressionType) { LeaveStreamOpen = true, };
writerOptions.ArchiveEncoding.Default = encoding ?? Encoding.Default;
using (var writer = WriterFactory.Open(stream, type, writerOptions)) { writer.WriteAll(ORIGINAL_FILES_PATH, "*", SearchOption.AllDirectories); } } CompareArchivesByPath(Path.Combine(SCRATCH2_FILES_PATH, archive), Path.Combine(TEST_ARCHIVES_PATH, archiveToVerifyAgainst));
using (Stream stream = File.OpenRead(Path.Combine(SCRATCH2_FILES_PATH, archive))) { ReaderOptions readerOptions = new ReaderOptions();
readerOptions.ArchiveEncoding.Default = encoding ?? Encoding.Default;

// Boolean XOR -- If the stream should be left open (true), then the stream should not be diposed (false)// and if the stream should be closed (false), then the stream should be disposed (true)var message = $"{nameof(options.LeaveStreamOpen)} is set to '{options.LeaveStreamOpen}', so {nameof(testStream.IsDisposed)} should be set to '{!testStream.IsDisposed}', but is set to {testStream.IsDisposed}"; Assert.True(options.LeaveStreamOpen != testStream.IsDisposed, message); } } } }
public void UseReader(IReader reader, CompressionType expectedCompression) {while (reader.MoveToNextEntry()) {if (!reader.Entry.IsDirectory) { Assert.Equal(expectedCompression, reader.Entry.CompressionType); reader.WriteEntryToDirectory(SCRATCH_FILES_PATH, new ExtractionOptions() { ExtractFullPath = true, Overwrite = true }); } } } }
Write(CompressionType.None, "Zip.none.noEmptyDirs.zip", "Zip.none.noEmptyDirs.zip", Encoding.UTF8);
Read("Zip.zipx", CompressionType.LZMA);
RAR 5 解密
7Zip 寫入
Zip64 解壓縮
多卷Zip支持
