Working with TORRENT files Leave feedback

In the BitTorrent file distribution system, a torrent file or METAINFO is a computer file that contains metadata about files and folders to be distributed, and usually also a list of the network locations of trackers, which are computers that help participants in the system find each other and form efficient distribution groups called swarms. A torrent file does not contain the content to be distributed; it only contains information about those files, such as their names, sizes, folder structure, and cryptographic hash values for verifying file integrity. 

Note

For more information on torrent files please refer to this article: https://en.wikipedia.org/wiki/Torrent_file

To get TORRENT file metadata, the following steps are needed to be followed:

1. Load a TORRENT file
2. Get the root metadata package
3. Extract  the native metadata package using TorrentRootPackage.TorrentPackage
4. Read the TORRENT file properties

AdvancedUsage.ManagingMetadataForSpecificFormats.Peer2Peer.TorrentReadNativeMetadataProperties

using (Metadata metadata = new Metadata(Constants.InputTorrent))
{
	var root = metadata.GetRootPackage<TorrentRootPackage>();

	Console.WriteLine(root.TorrentPackage.Announce);
	Console.WriteLine(root.TorrentPackage.Comment);
	Console.WriteLine(root.TorrentPackage.CreatedBy);
	Console.WriteLine(root.TorrentPackage.CreationDate);

	foreach (var file in root.TorrentPackage.SharedFiles)
	{
		Console.WriteLine(file.Name);
		Console.WriteLine(file.Length);
	}

	// ...
}

The GroupDocs.Metadata API also supports updating some metadata properties of a TORRENT file. Please see the code snippet below to learn how to do that.

AdvancedUsage.ManagingMetadataForSpecificFormats.Peer2Peer.TorrentReadNativeMetadataProperties

using (Metadata metadata = new Metadata(Constants.InputTorrent))
{
	var root = metadata.GetRootPackage<TorrentRootPackage>();
	Console.WriteLine(root.TorrentPackage.Announce);
	Console.WriteLine(root.TorrentPackage.Comment);
	Console.WriteLine(root.TorrentPackage.CreatedBy);
	Console.WriteLine(root.TorrentPackage.CreationDate);

	foreach (var file in root.TorrentPackage.SharedFiles)
	{
		Console.WriteLine(file.Name);
		Console.WriteLine(file.Length);
	}

	// ...
}

You may easily run the code above and see the feature in action in our GitHub examples:
