C# Regex match anything inside Parentheses

Question

I want to match anything inside parentheses but the result must exclude the parentheses as well.

Examples:
Initialize(P90W)
Brake(45X)

Answer 1

Remove the inner paranthesis and try again:

new Regex(@"(\([^\)]+\))");

When you do not escape paranthesis in regex, if you are using group match it will only return the content within the paranthesis. So if you have, new Regex(@'(a)(b))', match 1 will be a and match 2 will be b. Match 0 is the entire match.
