How to get a program/instrument title from a specific chunk of a MIDI file in DryWetMidi library?

I'm using DryWetMidi library in C# and trying to acquire a program/instrument title from a loaded chunk, but I fail to find such field that gives me the title. So far I just have:

var midiFile = MidiFile.Read("test.mid");
var tempoMap = midiFile.GetTempoMap();
var trackList = midiFile.GetTrackChunks().ToList();
var notes = trackList[0].GetNotes().ToList();

I expected to find something like:

var programNumber = trackList[0].ProgramNumber;

or

var programNumber = midiFile.GetProgramNumbers();

But I can't find such operations. Please let me know if there's any way to do this in DryWetMidi or in any external library.

TrackChunk has Events property which gives access to all MIDI events within a track chunk. Just find ProgramChangeEvent ones and collect program numbers:

var programNumbers = trackList[0]
    .Events
    .OfType<ProgramChangeEvent>()
    .Select(e => e.ProgramNumber)
    .ToArray();

DryWetMIDI has complete documentation. Please look into it to learn more: https://melanchall.github.io/drywetmidi.
