c# Regex repeat group and split comma

Question

I have a pattern like this ((1), (2), (3), ....)

And I started to create a regex to match this pattern.

\(\(\d+\)\)

This patternt matches only ((2)) pattern but I want to continue with comma, and repeat the group pattern like this: ((1), (2), (3), ....)

How can I do?

Answer 1

若要匹配整个输入行，请使用以下表达式： \\((\\(\\d+\\)|\\,\\s?)+\\)

Answer 2

The following regex will match entire pattern:

\((?:\(\d+\))(?:,\s\(\d+\))*\)
