Comment lire un .Fichier RTF à l'aide .NET 4.0

J'ai une meilleure solution avec WPF , à l'aide de TextRange.

FlowDocument document = new FlowDocument();

//Read the file stream to a Byte array 'data'
TextRange txtRange = null;

using (MemoryStream stream = new MemoryStream(data))
{
    //create a TextRange around the entire document
    txtRange = new TextRange(document.ContentStart, document.ContentEnd);
    txtRange.Load(stream, DataFormats.Rtf);
}

Maintenant, vous pouvez voir l'extrait du texte à l'intérieur de documentTextRange.Texte
