private void button1_Click(object sender, EventArgs e)
        {
            richTextBox1.SelectionColor = Color.Blue;
        }

        private void button2_Click(object sender, EventArgs e)
        {
            richTextBox1.SelectionColor = Color.Red;
        }

        private void button3_Click(object sender, EventArgs e)
        {
            richTextBox1.SelectionFont = new Font("雅黑", 18);
        }

        private void button4_Click(object sender, EventArgs e)
        {

        }

        private void button5_Click(object sender, EventArgs e)

            richTextBox1.SelectionColor = Color.Black;
            richTextBox1.SelectionBullet = false;
            richTextBox1.SelectionBackColor = Color.White;
