How to read the IPTC header of an image through C#?

Question

How to best read the IPTC header of an image ?

I have the following image and I needed to read her description (for a database of images), but I have already researched many ways that for me were a little confused.

Has anyone ever done this and can tell me the best way? I’m using ASP.NET MVC (C#). Follow what I want to read in the image:

In my view, System.Windows.Media.Imaging:

var stream = new FileStream("arquivo.jpg", FileMode.Open, FileAccess.Read);
var decoder = new JpegBitmapDecoder(stream, BitmapCreateOptions.None, BitmapCacheOption.None);
var metadata = decoder.Frames[0].Metadata as BitmapMetadata;
if(metadata != null)
    var dados = metadata.Keywords;

A more recent approach uses the Exiflib, obtaining EXIF data, which implements IPTC:

using (ExifReader reader = new ExifReader(@"arquivo.jpg"))
{
    // Os dados estão em `reader`.
}
