title: VB.net fastest way to check if a string contains 1 of many strings
body: <p>OK, so i want to check if a large string contains one (any) of many other strings within an array.</p>
  
  <p>I can loop through that array and perform 'if largestring.contains(arrayitem) do something then exit for' but i feel this is probably inefficient especially if the array of strings is very large.</p>
  
  <p>Plus the performance will vary depending on the position in the array of the found string
  Is there a better way to do this?</p>
