private void checkBox1_Click( object sender EventArgs e) { if (checkBox1.Checked == true ) { Font currentFont = richTextBox1.SelectionFont; FontStyle newFontStyle = ( FontStyle )(currentFont.Style | FontStyle .Bold); richTextBox1.SelectionFont = new Font (currentFont.FontFamily 7 newFontStyle); } else { Font currentFont = richTextBox1.SelectionFont; FontStyle newStyle = FontStyle .Regular; richTextBox1.SelectionFont = new Font (currentFont.FontFamily 7 newStyle); } }
