Firstly let me just say, I am not terribly good at C#(I've only had it for a month or so(thanks MS for the free VS2005 :D )) I'm mainly a C++ guy.
Anyway, I'm creating a little tool to highlight some script (this is just for fun), I have highlighting working from a article on CodeProject, but I can't seem to color the text only inside of quotes.

Heres the code I have at the moment:

if (token == "\'" || token.StartsWith("\'"))
{
int length = line.Length - (index - start);
string execText = richTextBox1.Text.Substring(index, length);
richTextBox1.SelectionStart = index;
richTextBox1.SelectionLength = length;
richTextBox1.SelectionColor = Color.Crimson;
richTextBox1.SelectionFont = new Font("Courier New", 10, FontStyle.Regular);
break;
}


Now this highlights fine and all, but it highlights everything after the first quote and doesn't stop until a new line. I want it to stop when it reaches the next '

Any help is greatly appreciated.
