The easiest way to keep the delimiters in the result is to use the Regex. Split method and construct a pattern using alternation in a group . The group is key to including the delimiters as part of the result, otherwise it will drop them.
The pattern would look like (word1|word2|wordN) and the parentheses are for grouping. Also, you should always escape each word, using the Regex. Escape method to avoid having them incorrectly interpreted as regex metacharacters.
