.NET中zip的压缩和解压——SharpCompress_reader.entry.filepath

   使用Packaging无法实现通用的zip（使用其他工具压缩）的解压，只支持通过Packaging压缩包zip的解压，而SharpZipLib是基于“GPL”开源方式，风险比较大。在codeplex找到一个更强大的压缩和解压开源库，SharpCompress，和DotNetZip一样都是“MS-PL”开源方式。

     SharpCompress支持的格式：
Archive Format     Compression Format(s)     Compress/Decompress     Archive API     Reader API     Writer API
Rar     Rar     Decompress(1)     RarArchive     RarReader     N/A
Zip(2)     None, DEFLATE, BZip2, LZMA/LZMA2, PPMd     Both     ZipArchive     ZipReader     ZipWriter
Tar     None, BZip2, GZip     Both     TarArchive     TarReader     TarWriter(3)
GZip (single file)     GZip     Both     GZipArchive     GZipReader     GZipWriter
7Zip(4)     LZMA, LZMA2, BZip2, PPMd, BCJ, BCJ2     Decompress     SevenZipArchive     N/A     N/A

(1) SOLID Rars are only supported in the RarReader API.
(2) Zip format supports pkware and WinzipAES encryption. However, encrypted LZMA is not supported.
(3) The Tar format requires a file size in the header. If no size is specified to the TarWriter and the stream is not seekable, then an exception will be thrown.
(4) The 7Zip format doesn't allow for reading as a forward-only stream so 7Zip is only supported through the Archive API。

    也支持流方式的压缩和解压：
Compressor     Compress/Decompress
BZip2Stream     Both
GZipStream     Both
DeflateStream     Both
LZMAStream     Both
PPMdStream     Both

 

 

 

 

 

 

 

 

 

 

 

      使用也比较简单：
显示行号 复制代码 ？ 解压Rar文件

    using (Stream stream = File.OpenRead(@"C:\Code\sharpcompress.rar"))
    {
        var reader = ReaderFactory.Open(stream);
        while (reader.MoveToNextEntry())
        {
            if (!reader.Entry.IsDirectory)
            {
                Console.WriteLine(reader.Entry.FilePath);
                reader.WriteEntryToDirectory(@"C:\temp", ExtractOptions.ExtractFullPath | ExtractOptions.Overwrite);
            }
        }
    }

显示行号 复制代码 ？ 解压zip文件

    var archive = ArchiveFactory.Open(@"C:\Code\sharpcompress\TestArchives\sharpcompress.zip");
               foreach (var entry in archive.Entries)
               {
                   if (!entry.IsDirectory)
                   {
                       Console.WriteLine(entry.FilePath);
                       entry.WriteToDirectory(@"C:\temp", ExtractOptions.ExtractFullPath | ExtractOptions.Overwrite);
                   }
               }

显示行号 复制代码 ？ 压缩成zip文件

    using (var archive = ZipArchive.Create())
    {
        archive.AddAllFromDirectoryEntry(@"C:\\source");
        archive.SaveTo("@C:\\new.zip");
    }

using (Stream stream = File.OpenWrite(tarPath))

using (var writer = WriterFactory.Open(ArchiveType.Tar, stream))

{

    writer.WriteAll(filesPath, "*", SearchOption.AllDirectories);

}

using (Stream stream = File.OpenWrite(tarbz2Path))

using (var writer = WriterFactory.Open(ArchiveType.BZip2, stream))

{

    writer.Write("Tar.tar", tarPath);

}

 

 
显示行号 复制代码 ？ 创建Tar文件

    using (Stream stream = File.OpenWrite(tarPath))
    using (var writer = WriterFactory.Open(ArchiveType.Tar, stream))
    {
        writer.WriteAll(filesPath, "*", SearchOption.AllDirectories);
    }
    using (Stream stream = File.OpenWrite(tarbz2Path))
    using (var writer = WriterFactory.Open(ArchiveType.BZip2, stream))
    {
        writer.Write("Tar.tar", tarPath);
    }
