How to open and read the content of ".RTF" File using c#

My need : I need to open an RTF File and read the content inside the RTF File and store it in a string variable.

What i have done : I have done it using "microsoft.office.interop.word.dll" ie.. Docment.open(String Filename);

But My Final necessity is : I need to open it using some other way to read the RTF File. This is Because in AzureFunction (microsoft.office.interop.word.dll is not supported ) ie.. word cant be installed in server.

OpenXML - This is used to open word , excel , powerpoint files . it cannot able to open RTF File.

Any possible answer is welcomed.

If you want to convert an RTF file to plain text, keeping only the text and losing all formatting and other non-text elements such as bitmaps, it is possible by using System.Windows.Forms.RichTextBox.

Note that you do not need an application with a user interface to do this; you can use RichTextBox in, for example, a service - but you will need to reference System.Windows.Forms.dll in order to do so.

The code to convert from an RTF file to a plain text string would look like this:

using System.Windows.Forms;

public static string RtfFileAsPlainText(string rtfPathName)
{
    using (var rtf = new RichTextBox())
    {
        rtf.Rtf = File.ReadAllText(rtfPathName);
        return rtf.Text;
    }
}
