Select Text in a multiline textbox, move it to another multiline textbox on a button click in C#
<p>I have a problem that I haven't come across yet that I hope some of you may help me with. I am trying to select a single line, either the fist, second, or last line in a multiline textbox and move it to another multiline textbox with a button click in C#. I am unsure how to select just a single line at a time, then add it to the other multiline textbox. If anyone has some insight, that would be great! Thank you!</p>
