将文本框插入符号/光标定位到与其他文本框C＃相同的行

Question

我一直在寻找，但是我尝试过的任何方法都没有用。

我基本上想从一个文本框中选择插入符号所在的行，然后将第二个文本框滚动到相同位置。

这是我尝试的：

        int line = textBox1.GetLineFromCharIndex(textBox1.SelectionStart);
        Point pNew = new Point();
        pNew.X = 0;
        pNew.Y = line;
        textBox2.SelectionStart = textBox2.GetCharIndexFromPosition(pNew);
        textBox2.ScrollToCaret();

我要做的就是保持第二个文本框的滚动与第一个文本框的滚动相同。

Answer 1

这是你想要的吗 ：

       textBox2.SelectionStart = textBox1.SelectionStart;
       textBox2.ScrollToCaret();

这在两个文本框文本相等的地方有效。

我没有得到您All I want to do is keep the second textbox as scrolled as much as the first textbox.的All I want to do is keep the second textbox as scrolled as much as the first textbox.目的， All I want to do is keep the second textbox as scrolled as much as the first textbox. 我认为：两个TextBox具有相同的Text。
