Compresss by Squid-Box.SevenZipSharp.Lite
choose x86/x64 7z dll
if (IntPtr.Size == 4)
{
SevenZipExtractor.SetLibraryPath(@"x86\7z.dll");
}
else
{
SevenZipExtractor.SetLibraryPath(@"x64\7z.dll");
}
if (IntPtr.Size == 4)
{
SevenZipCompressor.SetLibraryPath(@"x86\7z.dll");
}
else
{
SevenZipCompressor.SetLibraryPath(@"x64\7z.dll");
}
Decompression As File
using (SevenZipExtractor tmp = new SevenZipExtractor("Name.7z")))
{
for (int i = 0; i < tmp.ArchiveFileData.Count; i++)
{
tmp.ExtractFiles("Path to sotre decompression file", tmp.ArchiveFileData[i].Index);
}
}
Compress to memoryStream
SevenZipCompressor ziper = new SevenZipCompressor()
{
ArchiveFormat = OutArchiveFormat.SevenZip,
DirectoryStructure = false
};
using (MemoryStream zippedStream = new MemoryStream())
{
ziper.DefaultItemName = "DefaultItemName ";
ziper.CompressStream(InputOrginalStream, ZipedOutStream);
using (FileStream fs = new FileStream("Path to store", FileMode.Create))
{
using (BinaryWriter bw = new BinaryWriter(fs))
{
bw.Write(zippedStream.ToArray());
}
}
}
Extract file to memeory stream (nuget SevenZipExtractor)
using SevenZipExtractor;
MemoryStream outStream = new MemoryStream();
using (ArchiveFile archiveFile = new ArchiveFile("path of zipped file"))
{
foreach (Entry entry in archiveFile.Entries)
{
//Console.WriteLine(entry.FileName);
//Console.WriteLine("Extract" + outStream.Length);
entry.Extract(outStream);
}
}
