here's interesting question, have list contains 3 sentences such as:

bill cat had

bill had cat

cat had bill

how utilize .contains() or other method check if sentences in list contains words in specific order, algorithm shown below:

1) run sentence list through foreach loop

2) check if sentence contains words in order => bill + had + cat

3) homecoming sentence

so every other sentence returned false since order of words different. ideas on implementing this, folks? :)

try below solution works.

class programme { static void main(string[] args) { list<string> list = new list<string>(); list.add("bill cat had"); list.add("bill had cat"); list.add("bill had cat"); list.add("cat had bill"); regex rex = new regex(@"((bill)).*((had)).*((cat))"); foreach (string str in list) { if (rex.ismatch(str)) { console.writeline(str); } } console.readline(); } }

c# string foreach order condition
