使用ZipOutputStream压缩子文件夹

ZipOutputStream仅ZipOutputStream文件夹中的文件。 我也想压缩子文件夹。 我怎样才能做到这一点？

Answer 1

您必须递归浏览目录才能添加zip中的所有文件。

如果您愿意，请看这个小帮手：

  using ICSharpCode.SharpZipLib.Zip; using ICSharpCode.SharpZipLib.Checksums; using System.IO; using System; using System.Collections.Generic; using System.Text; using System.Collections; using System.Text.RegularExpressions; namespace Zip { /// 
 /// Uses Sharpziplib so as to create a non flat zip archive /// 
 public abstract class ZipManager { /// 
 /// will zip directory .\toto as .\toto.zip /// 
 ///  ///  public static string CreateZip(string stDirToZip) { try { DirectoryInfo di = new DirectoryInfo(stDirToZip); string stZipPath = di.Parent.FullName + "\\" + di.Name + ".zip"; CreateZip(stZipPath, stDirToZip); return stZipPath; } catch (Exception) { throw; } } /// 
 /// Main method /// 
 /// path of the archive wanted /// path of the directory we want to create, without ending backslash public static void CreateZip(string stZipPath, string stDirToZip) { try { //Sanitize inputs stDirToZip = Path.GetFullPath(stDirToZip); stZipPath = Path.GetFullPath(stZipPath); Console.WriteLine("Zip directory " + stDirToZip); //Recursively parse the directory to zip Stack stackFiles = DirExplore(stDirToZip); ZipOutputStream zipOutput = null; if (File.Exists(stZipPath)) File.Delete(stZipPath); Crc32 crc = new Crc32(); zipOutput = new ZipOutputStream(File.Create(stZipPath)); zipOutput.SetLevel(6); // 0 - store only to 9 - means best compression Console.WriteLine(stackFiles.Count + " files to zip.\n"); int index = 0; foreach (FileInfo fi in stackFiles) { ++index; int percent = (int)((float)index / ((float)stackFiles.Count / 100)); if (percent % 1 == 0) { Console.CursorLeft = 0; Console.Write(_stSchon[index % _stSchon.Length].ToString() + " " + percent + "% done."); } FileStream fs = File.OpenRead(fi.FullName); byte[] buffer = new byte[fs.Length]; fs.Read(buffer, 0, buffer.Length); //Create the right arborescence within the archive string stFileName = fi.FullName.Remove(0, stDirToZip.Length + 1); ZipEntry entry = new ZipEntry(stFileName); entry.DateTime = DateTime.Now; // set Size and the crc, because the information // about the size and crc should be stored in the header // if it is not set it is automatically written in the footer. // (in this case size == crc == -1 in the header) // Some ZIP programs have problems with zip files that don't store // the size and crc in the header. entry.Size = fs.Length; fs.Close(); crc.Reset(); crc.Update(buffer); entry.Crc = crc.Value; zipOutput.PutNextEntry(entry); zipOutput.Write(buffer, 0, buffer.Length); } zipOutput.Finish(); zipOutput.Close(); zipOutput = null; } catch (Exception) { throw; } } static private Stack DirExplore(string stSrcDirPath) { try { Stack stackDirs = new Stack(); Stack stackPaths = new Stack(); DirectoryInfo dd = new DirectoryInfo(Path.GetFullPath(stSrcDirPath)); stackDirs.Push(dd); while (stackDirs.Count > 0) { DirectoryInfo currentDir = (DirectoryInfo)stackDirs.Pop(); try { //Process .\files foreach (FileInfo fileInfo in currentDir.GetFiles()) { stackPaths.Push(fileInfo); } //Process Subdirectories foreach (DirectoryInfo diNext in currentDir.GetDirectories()) stackDirs.Push(diNext); } catch (Exception) {//Might be a system directory } } return stackPaths; } catch (Exception) { throw; } } private static char[] _stSchon = new char[] { '-', '\\', '|', '/' }; } }

 public static void ZipDirectoryKeepRelativeSubfolder(string zipFilePath, string directoryToZip) { var filenames = Directory.GetFiles(directoryToZip, "*.*", SearchOption.AllDirectories); using (var s = new ZipOutputStream(File.Create(zipFilePath))) { s.SetLevel(9);// 0 - store only to 9 - means best compression var buffer = new byte[4096]; foreach (var file in filenames) { var relativePath = file.Substring(directoryToZip.Length).TrimStart('\\'); var entry = new ZipEntry(relativePath); entry.DateTime = DateTime.Now; s.PutNextEntry(entry); using (var fs = File.OpenRead(file)) { int sourceBytes; do { sourceBytes = fs.Read(buffer, 0, buffer.Length); s.Write(buffer, 0, sourceBytes); } while (sourceBytes > 0); } } s.Finish(); s.Close(); } }

C＃MVP Peter Bromberg撰写的这篇文章可以解决您的问题： 使用C＃压缩/解压缩文件夹和文件 。 它有完整的代码和示例项目。

我偶然发现的替代（和更方便）的解决方案：

使用SevenZipSharp项目

 var compressor = new SevenZipCompressor(); compressor.ArchiveFormat = OutArchiveFormat.SevenZip; compressor.CompressionLevel = CompressionLevel.High; compressor.CompressionMode = CompressionMode.Create; compressor.PreserveDirectoryRoot = false; compressor.FastCompression = true; compressor.CompressDirectory(dir.FullName, zipFile.FullName);
