Reading RTF Files line by line in C# WPF

I am working on a C# WPF tool, which shall read different text file types and analyze the file line by line.

It works properly for example for a .asc text file:

foreach (string line in File.ReadLines(myFile.asc)) {
  AnalyzeCurrentLine(line);
}

Now it becomes difficult for me reading a RTF file. I still want to read it line by line. The format of the text is not relevant. Is a RichTextBox object the correct way for this?

You could use a RichTextBox to load your RTF and then read its content line by line like this:

RichTextBox rtb = new RichTextBox();
string rtf = File.ReadAllText("file.rtf");
using (MemoryStream stream = new MemoryStream(Encoding.Default.GetBytes(rtf)))
    rtb.Selection.Load(stream, DataFormats.Rtf);

string text = new TextRange(rtb.Document.ContentStart, rtb.Document.ContentEnd).Text;
string[] lines = text.Split(new[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries);
foreach(string line in lines)
{
    //...
}
