richtextbox控件内容的格式

Question

那得看要显示的内容在数据库里存的是什么格式this.richTextBox1.AppendText("111\r\n2222222\r\n\t\t\t\t333\r\n\t\t\t\t444");

Answer 1

他想设置文本居中...
richtextbox就跟文本文档一样,没有那一说.
想居中,自己算一行能显示多少个字,然后空格补齐吧...

Answer 2

        private void button1_Click(object sender, EventArgs e)
        {
            richTextBox1.SelectionAlignment = HorizontalAlignment.Left;
        }        private void button2_Click(object sender, EventArgs e)
        {
            richTextBox1.SelectionAlignment = HorizontalAlignment.Center;
        }        private void button3_Click(object sender, EventArgs e)
        {
            richTextBox1.SelectionAlignment = HorizontalAlignment.Right;
        }
    }
