Using .85

The following code creates a corrupt zip file. It works fine if the line setting the password is removed.

    public static void CreateZip(string zipFileName, string password, params string[] inputFiles)
    {
      using (ZipOutputStream zipOutputStream = new ZipOutputStream(File.Create(zipFileName)))
      {
        zipOutputStream.SetLevel(9); // 0 - store only to 9 - means best compression

         // comment out the following line to make the code work
        if (password != null) zipOutputStream.Password = password;

        byte[] buffer = new byte[4096];
        foreach (string file in inputFiles) {
                   
                    ZipEntry entry = new ZipEntry(Path.GetFileName(file));
                    entry.DateTime = DateTime.Now;
                    zipOutputStream.PutNextEntry(entry);
                    using ( FileStream fs = File.OpenRead(file) ) {
       
                        int sourceBytes;
                        do {
                            sourceBytes = fs.Read(buffer, 0, buffer.Length);
                            zipOutputStream.Write(buffer, 0, sourceBytes);
                            } while (sourceBytes > 0);
                 }
        }
   }
  

Thanks. 

Actually, this is fixed in .85.1. The build properties must be modified: Uncheck "Check for arithmetic overflow/underflow".
