I'm not too familiar with .NET, so I can't tell you exactly what would
correspond to the above code. Vala uses GLib's regular expressions
(GRegex, bound in glib-2.0.vapi as GLib.Regex). Documentation of the
syntax is available at [1], C API at [2]. I think you'll be especially
interested in the GRegexCompileFlags documentation.

You may also be interested in the experimental regular expression
syntax. There is a brief explanation at [3].
