项目简介项目结构压缩核心代码 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;
using (var reader = ReaderFactory.Open(NonDisposingStream.create(stream), readerOptions)) { reader.WriteAllToDirectory(SCRATCH_FILES_PATH, new ExtractionOptions() { ExtractFullPath = true }); } } VerifyFiles(); } 解压核心代码 public abstract class ReaderTests : TestBase { protected void Read(string testArchive, CompressionType expectedCompression, ReaderOptions options = null) { testArchive = Path.Combine(TEST_ARCHIVES_PATH, testArchive);
options = options ?? new ReaderOptions();
options.LeaveStreamOpen = true; ReadImpl(testArchive, expectedCompression, options);
options.LeaveStreamOpen = false; ReadImpl(testArchive, expectedCompression, options); VerifyFiles(); }
private void ReadImpl(string testArchive, CompressionType expectedCompression, ReaderOptions options) { using (var file = File.OpenRead(testArchive)) { using (var protectedStream = NonDisposingStream.create(new ForwardOnlyStream(file), throwOnDispose: true)) { using (var testStream = new TestStream(protectedStream)) { using (var reader = ReaderFactory.Open(testStream, options)) { UseReader(reader, expectedCompression); protectedStream.ThrowOnDispose = false; Assert.False(testStream.IsDisposed, "{nameof(testStream)} prematurely closed"); }
// 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 }); } } } } zip压缩用法 Write(CompressionType.None, "Zip.none.noEmptyDirs.zip", "Zip.none.noEmptyDirs.zip", Encoding.UTF8); zip解压用法 Read("Zip.zipx", CompressionType.LZMA);
