c# - how to match multiple words in string using regex? -

i trying match 3 words can appear anywhere in string:

win enter

all 3 words must exist in string return match. having issues getting match when 3 words exist.

^(?=.*?win)(?=.*?(enter))(?=.*?(now)).*

regex working when 3 words within same line... when spread out across entire string on different lines, failing match.

any direction or appreciated.

i think c# support (?s) dotall modifier. if yes try below regex,

(?i)(?s)win.*?enter.*?now
