1.Change text color in text box
richTextBox1.SelectionColor = Color.Red;
richTextBox1.AppendText("0123456789");
3.修改字串中的字體顏色
richTextBox1.AppendText("0123456789");
richTextBox1.Select(3, 2);
richTextBox1.SelectionColor = Color.Red;
(3.測試中...)
richTextBox1.AppendText("0123456789");
richTextBox1.Select(1, 2);
Font oldFont = richTextBox1.SelectionFont;
richTextBox1.SelectionFont = new Font(oldFont, FontStyle.Bold);
richTextBox1.AppendText("\r\naaa");
2.自動滾動到最下面(自動滾動到文字新增處)
/*Scroll to the bottom of the page*/ textBox1.SelectionStart = textBox1.Text.Length; textBox1.ScrollToCaret();
