Wow, really clean! Awesome!!

Nice suggestion!

Wow, I just learned from your code. Good stuff.

Clever, way better than my solution

Regex is overkill for anything.

If it's a very simple parse, like this, you'll get better performance and code that's easier to read by just writing it out imperatively. If it's a complicated parse, you'll be less likely to run into bugs, and have code that's easier to read, by using a proper parser DSL such as ANTLR. Regex isn't particularly good at either case, and its complexlity is extremely high. The "now you have two problems" joke exists for a reason.

Trim replaces the spaces only in the beginning or end of a string. It combines "TrimStart" and "TrimEnd".

I thought Trim erase all spaces!, Does this only trim the two sides?

Is regex an overkill for this one? Just asking because I'm not really familiar with regex.

Honestly, i am totally lost.Could anyone explain the purpose of that for loop for me please.

i was wondering about using a LINQ ; but yeah Regex does the work
