people think that the object using this class can only match the first item, in fact, all matching items can be traversed. Previously, I tried to make it easier without looking up any information. I just thought about the official materials. I thought it was the same as my thinking, but I thought about it again, you don't have to spend time thinking about it.

This is the most standard syntax: to customize a function, and then use this function delegate as a parameter to instantiate the matchevaluator object. Finally, you can use this object for parameter input during regular expression matching, manual processing of matching results.
