c# - 将我当前的光标位置显示为当前行和当前列？

Question

我正在开发使用 RichtextBox、Menustrip 和更多控件的 Windows 窗体应用程序。

我已经完成了一些工作，但无法正常工作。当我的鼠标光标在 RichTextBox 中移动时，我想自动更改位置，就像在简单的记事本上那样。

我的位编码是....

我想要它，所以当我的鼠标光标移动时，它会改变我状态栏上的动态位置

private void sizeToolStripMenuItem_Click(object sender, EventArgs e)
{        
    int line = richTextBox1.GetLineFromCharIndex(richTextBox1.SelectionStart);
    int column = richTextBox1.SelectionStart - richTextBox1.GetFirstCharIndexFromLine(line);
    toolStripStatusLabel5.Text ="Line"+" "+ line.ToString();
    toolStripStatusLabel6.Text = " Column" + " " + line.ToString();
    toolStripStatusLabel3.Text= Cursor.Position.ToString(); // where is my mouse cursor at this Time like that x and y cordinate 330,334
}

每次按回车键时显示你的行。代码如下:::----

private void Key_Down(object sender, KeyEventArgs e)
{
    if (e.KeyData == Keys.Enter)
    {
        int line = richTextBox1.GetLineFromCharIndex(richTextBox1.SelectionStart);
        int column = richTextBox1.SelectionStart - richTextBox1.GetFirstCharIndexFromLine(line);

        toolStripStatusLabel5.Text = "Line" + " " + line.ToString();
        toolStripStatusLabel6.Text = " Column" + " " + column.ToString();
        toolStripStatusLabel3.Text = Cursor.Position.ToString(); // where is my mouse cursor at this Time like that x and y cordinate 330,334
        Update();
    }
}
