C# read rtf file?

Posted on 2013-06-25

I have a rtf file that contains some text and would like to read and parse its contents and probably load them in database.

I can read and process txt files using StreamReader's readline method. but when I try the same thing on rtf file it adds formatting and some non-readable text in the data string so the end result is not what I expect.

How can I process this rtf file? Would I need to manually copy the content of this rtf file and paste it in txt file before processing or is there a better way to directly process rtf files?


using (StreamReader sr = new StreamReader(FileName))
      {
            string strInputRcd;

// Read and display lines from the file until the end of
// the file is reached.
      while ((strInputRcd = sr.ReadLine()) != null)
            {
                                 
                                 }

Thanks

You really should go with a text file instead. The RTF file will contain a whole lot of formatting information which makes no sense at all to the stream reader. Your database only cares about the text, not what colour, size, font or position that text should have.

I generally try to avoid importing massive libraries just for the sake of one feature, but in the case of RTF I tend to make an exception. If, counter to duttcom's suggestioni, you are going to stick with an RTF file, then you might consider adding a reference to the System.Windows.Forms.dll library. Then you can create an instance of a RichTextBox control. You can load the RTB with your RTF code, then extract just the text by accessing the Text property.

e.g.

// with a reference to System.Windows.Forms added


namespace _28167832
{
    class Program
    {
        static void Main(string[] args)
        {
            System.Windows.Forms.RichTextBox rtb = new System.Windows.Forms.RichTextBox();

            rtb.Rtf = @"{\rtf1\ansi{\fonttbl\f0\fswiss Helvetica;}\f0\pard Hello World.\par}";

            string text = rtb.Text;
        }
    }
}
