title: vb.net - case sensitive/insensitive search text in a string
body: <p>I've been using text.indexof() to see if a string is located inside another string, however is it it possible to do a case sensitive/insensitive search option? I've been looking around Google and not having much luck with it.</p>
  
  <p>A huge bonus would be if it could count the number of occurrences inside the string!</p>
