UB: C#'s Regex.Match returns whole string instead of part when matching

Question

Attention! This is NOT related to Regex problem, matches the whole string instead of a part

Hi all. I try to do

Match y = Reg         


        

Answer 1

There is one capture group in the pattern; that is group 1.

There is always group 0, which is the entire match.

Therefore there are a total of 2 groups.
