  Unzip files using c# code

  Dec 25, 2012 12:16 PM|LINK

  UP!Help please me!

  I was use ICSharpCode.SharpZipLib.dll to compress files.

  And now, how to recompress&

  
  

  public static void WriteZipFile(List<string> filesToZip, string path, int compression)
          {
  
              //if (compression < 0 || compression > 9)
              //    throw new ArgumentException("Invalid compression rate.");
  
              //if (!Directory.Exists(new FileInfo(path).Directory.ToString()))
              //    throw new ArgumentException("The Path does not exist.");
  
              foreach (string c in filesToZip)
                  if (!File.Exists(c))
                      throw new ArgumentException(string.Format("The File{0}does not exist!", c));
  
              ZipOutputStream stream = new ZipOutputStream(File.Create(path));
              stream.SetLevel(compression);
  
              for (int i = 0; i < filesToZip.Count; i++)
              {
                  ZipEntry entry = new ZipEntry(Path.GetFileName(filesToZip[i]));
                  entry.DateTime = DateTime.Now;
                  var md5 = MD5.Create();
                  using (FileStream fs = File.OpenRead(filesToZip[i]))
                  {
  
                      byte[] buffer = new byte[fs.Length];
                      byte[] cheksum = md5.ComputeHash(fs);
                      fs.Read(buffer, 0, buffer.Length);
                      entry.Size = fs.Length;
                      fs.Close();
                      entry.Crc = Convert.ToUInt32(cheksum);
                      stream.PutNextEntry(entry);
                      stream.Write(buffer, 0, buffer.Length);
                  }
              }
              stream.Finish();
              stream.Close();
          }
