如何避免在RichTextbox的末尾添加空行？

Question

foreach (string link in links)
{
    rtbPaths.AppendText(link + Environment.NewLine);
}
foreach (string link in links1)
{
    rtbPaths.AppendText(link + Environment.NewLine);
}

The problem is when the second foreach finishes there is an empty line at the bottom of the RichTextbox. How can I make that it will not add the empty line at the end?

Answer 1

rtbPaths.AppendText(string.Join(Environment.NewLine, links));
rtbPaths.AppendText(Environment.NewLine);
rtbPaths.AppendText(string.Join(Environment.NewLine, links1));

or just

rtbPaths.AppendText(string.Join(Environment.NewLine, links.Concat(links1)));
