  • You can just use a RichTextBox

  • Hi Noidfactor,

    Thank you for posting here.

    According to your description, you’d like to modify the text within a RTF file and save to another file..

    As we know The Rich Text Format (often abbreviated RTF) is a proprietary document file format with published specification developed by Microsoft Corporation for cross-platform document interchange with Microsoft products. So, RTF files can be convert to plain text. Then we can print it and save it as a rtf file.

    Following codes show how to read and write a RTF file:

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    namespace ConsoleApplication1
        class Program
            static void Main()
                string path = @"C:\test\Readlines.rtf";
                System.Windows.Forms.RichTextBox rtBox = new System.Windows.Forms.RichTextBox();
                string rtfText = System.IO.File.ReadAllText(path);
                rtBox.Rtf = rtfText;
                string plainText = rtBox.Text;
                using (System.IO.StreamWriter file =
                    new System.IO.StreamWriter(@"C:\test\WriteLines.rtf"))

    Here is my output.

    Before run
