We need an example with a magnet

[IGNATOV93]

Good day, who can give an example of a code for obtaining meta-information through a magnet? But the same distribution in a couple of seconds is determined in the torrent client on the pc qbittorrent .I will be very grateful

In the ClientEngine class, there is a DownloadMetadataAsync method that can help you download torrent files from a magnet URI. You can see how it works from the source code:

monotorrent/src/MonoTorrent.Client/MonoTorrent.Client/ClientEngine.cs

Line 587 in 9e98a44

public async Task<ReadOnlyMemory<byte>> DownloadMetadataAsync (MagnetLink magnetLink, CancellationToken token)

However, if you need more customization, such as adding more custom trackers (which is usually necessary for metadata-type download tasks), you will need to handle the initialization yourself and call the TorrentManager.StartAsync(metadataOnly: true) method.
Unfortunately, the current async Task StartAsync(bool metadataOnly) method is internal, so you may need to modify the source code of the monotorrent library to call it from outside.

monotorrent/src/MonoTorrent.Client/MonoTorrent.Client/ClientEngine.cs

Line 816 in 9e98a44

internal async Task StartAsync ()
