Regex Indexer Question.

[Ben Dewey]

I am trying to get the parts of a regular expression. This is a simplified
version of what I am trying to do.

expression:
((\w)+)

source:
something

results:
$1 = something
$2 = g

Is there any way to get an indexer for $2. For example $2.4 or $2(4) would
get me the fourth letter.

Hello Ben,

I don't think there is a way to do the indexing like you want. However you could always just capture the 4 char as a another cature group for example:

((\w\w\w(\w))+)

Look at the documentation for Group.Captures: I think it does exactly what
you want.
