[Débutant] Convertir un fichier rtf (tx

Bonjour,

Avez-vous une méthode pour transformer un contenu rtf en html ?

J'ai bien trouvé un source: https://code.msdn.microsoft.com/wind...F-and-aaa02a6e

mais il me donne un problème de:

Code:

Informations supplémentaires : Le thread appelant doit être en mode STA, comme l'exigent de nombreux composants de l'interface utilisateur.
 
Quand je veux utiliser la méthode:

MarkupConverter markupConverter = new MarkupConverter();
            string rtf = string.Empty;
            string test = string.Empty;
 
            System.IO.StreamReader file = new System.IO.StreamReader(@"C:\Users\c.cavenaile\Downloads\MarkupConverter\MarkupConverter\test.txt");
            string line = file.ReadLine();
            while ((line = file.ReadLine()) != null)
            {
                rtf += line;
            }
 
            file.Close();
            test = markupConverter.ConvertRtfToHtml(line);
 
            Console.WriteLine(test);

        }
 
 
    }
}

et je n'arrive pas a afficher le html

[EDIT2]
Autre solution c'est de passé du RTF en xaml pour ensuite le convertir en html.

Pour la première étape, j'ai trouvé facilement, il me reste maintenant la conversion du xaml en html, avez vous une idée ?

Merci
