C# remove all spaces, but not in quotes

Question

I need to a remove spaces from string, but not between quotes.
Like if string is:
word1 word2 word3 "word4 word5" word6
Output will need to be:
word1word2word3"word4 word5"word6

Help me, i know a one way to do it, but its too big way.

Answer 1

Split input with quote obtaining that every even items are the quoted input then split the odds items with space for get the un-quoted items... Example:

Input :
word1 word2 "i am quoted"

Splitting input with quote you would get:
["word1 word2 ", "i am quoted", ""]

Every even items (then at odd index) represent the quoted input then:
quoted= ["i am quoted"]

Instead every odd items (then at even index) represents un-quoted input to split:

unquoted= ["word1 word2"]
that splitted with space
unquoted= ["word1", "word2",""]

Obliviously you can ignore empty strings

Answer 2

Answer 3

What you mean for "better way"? More performant? Less code? What is the real problem?
