Regular expression AND operator in .net framework

Question

You can do this in Perl/Java ( example )

Is it possible to do this in c#?

Answer 1

Yes, you can do that in C#. It's called a positive lookahead assertion. See this table for a comparison of the capabilities of various regular expression engines (search for lookaround on that page).

On a related note, C# also supports variable width lookbehind assertions - something that most other engines do not support.
