使用方法：

 



       private void menuItem10_Click(object sender, System.EventArgs e)
 
        {
 
            string[] _about = new string[10];
 
            Font[] _fonts = new Font[3];
 
 
 
            rtBox_Main.Rtf = "";
 
 
 
            _fonts[0] = new Font(FontFamily.GenericSerif, 16f);
 
            _fonts[1] = new Font(FontFamily.GenericSansSerif, 12f);
 
            _fonts[2] = new Font(FontFamily.GenericMonospace, 8f);
 
 
 
            _about[0] = "This text and images are ";
 
            _about[1] = "being inserted on the\n";
 
            _about[2] = "Click ";
 
            _about[3] = "event of this menu item.\n\n";
 
            _about[4] = "Sorry I cleared the document, ";
 
            _about[5] = " but just click ";
 
            _about[6] = "undo ";
 
            _about[7] = "and you'll be ok. ";
 
            _about[8] = "\n\nHa Ha!  No undo.\n\n";
 
            _about[9] = "Khendys was here ...";
 
 
 
            rtBox_Main.InsertTextAsRtf(_about[0], _fonts[0]);
 
            rtBox_Main.InsertTextAsRtf(_about[1], new Font(_fonts[1], FontStyle.Strikeout));
 
            rtBox_Main.InsertTextAsRtf(_about[2], new Font(_fonts[0], FontStyle.Bold | FontStyle.Italic), RtfColor.Olive, RtfColor.Aqua);
 
            rtBox_Main.InsertTextAsRtf(_about[3], new Font(_fonts[1], FontStyle.Italic), RtfColor.Gray);

            rtBox_Main.InsertTextAsRtf(_about[6], _fonts[0], RtfColor.Blue, RtfColor.Aqua);
