RichTextBox點擊選擇下面的線

Question

如何選擇我點擊下面的線？ 到目前爲止，我有這個How to select a line in a RichTextBox on a mouse click? 感謝

Answer 1

這個答案是你的第二個問題，即：我怎麼分配這個選擇的變量？ ：|我需要分配選定的行到X和行下面的Y.

private void richTextBox1_MouseClick(object sender, MouseEventArgs e) 
    { 
     RichTextBox richTextBox = ((RichTextBox)sender); 

     SendKeys.Send("{HOME}+{END}"); 
     SendKeys.Flush(); 

     string X = richTextBox.SelectedText; 

     SendKeys.Send("{DOWN}"); 
     SendKeys.Send("{HOME}+{END}"); 
     SendKeys.Flush(); 

     string Y = richTextBox.SelectedText; 
    } 

Answer 2

private void richTextBox1_MouseClick(object sender, MouseEventArgs e) 
{ 
    SendKeys.Send("{DOWN}");//Move cursor to next line 
    SendKeys.Send("{HOME}+{END}");//Select the line 
}
