Get plain text from an RTF text

Question

I have on my database a column that holds text in RTF format.

How can I get only the plain text of it, using C#?

Thanks :D

Solution 1

Microsoft provides an example where they basically stick the rtf text in a RichTextBox and then read the .Text property... it feels somewhat kludgy, but it works.

static public string ConvertToText(string rtf)
{
   using(RichTextBox rtb = new RichTextBox())
   {
       rtb.Rtf = rtf;
       return rtb.Text;
   }
}

Solution 2

for WPF you can use (using Xceed WPF Toolkit) this extension method :

public static string RTFToPlainText(this string s)
    {
       // for information : default Xceed.Wpf.Toolkit.RichTextBox formatter is RtfFormatter 
        Xceed.Wpf.Toolkit.RichTextBox rtBox = new Xceed.Wpf.Toolkit.RichTextBox(new System.Windows.Documents.FlowDocument());
        rtBox.Text = s;
        rtBox.TextFormatter = new Xceed.Wpf.Toolkit.PlainTextFormatter();
        return rtBox.Text;

    }
