Hi,
I have used the following code to zip files.
// Depending on the directory this could be very large and would require more attention
// in a commercial package.string[ filenames = Directory.GetFiles(args[0]);
// 'using' statements gaurantee the stream is closed properly which is a big source
// of problems otherwise. Its exception safe as well which is great.using (ZipOutputStream s = new ZipOutputStream(File.Create(args[1]))) {
s.SetLevel(9);
// 0 - store only to 9 - means best compression
byte[ buffer = new byte[4096];
foreach (string file in filenames) {
// Using GetFileName makes the result compatible with XP
// as the resulting path is not absolute.ZipEntry entry = new ZipEntry(Path.GetFileName(file));
// Setup the entry data as required.
// Crc and size are handled by the library for seakable streams
// so no need to do them here.
// Could also use the last write time or similar for the file.entry.DateTime = DateTime.Now;
s.PutNextEntry(entry);
using ( FileStream fs = File.OpenRead(file) ) {
// Using a fixed size buffer here makes no noticeable difference for output
// but keeps a lid on memory usage.int sourceBytes;do {
sourceBytes = fs.Read(buffer, 0, buffer.Length);
s.Write(buffer, 0, sourceBytes);
} while ( sourceBytes > 0 );
}
}
// Finish/Close arent needed strictly as the using statement does this automatically
// Finish is important to ensure trailing information for a Zip file is appended. Without this
// the created file would be invalid.
s.Finish();
// Close is important to wrap things up and unlock the file.
s.Close();
}
But once I zipped the files using the above code, I can not unzip the file by using winRAR software. It gave an error like unknown method.
Does anybody know how to solve this if so pls let me know...
Thanks.
