Hello,

I am trying to find every "a -> b, c, d" pattern in an input string. The pattern I am using is the following :

"^[ \t]*(\\w+)[ \t]*->[ \t]*(\\w+)(,[ \t]*\\w+)*$"

The input is :

a -> b
b -> c
c -> d

The function is :

private void ParseAndBuildGraph(String input) {
    MatchCollection mc = Regex.Matches(input, "^[ \t]*(\\w+)[ \t]*->[ \t]*(\\w+)(,[ \t]*\\w+)*$", RegexOptions.Multiline);
    foreach (Match m in mc) {
        Debug.WriteLine(m.Value);
    }
}

The output is :

c -> d

Actually, there is a problem with the line ending "$" special char. If I insert a "\r" before "$", it works, but I thought "$" would match any line termination (with the Multiline option), especially a \r\n in a Windows environment. Is it not the case ?
