title: vb.net string.split vs substring.lastindexof - which is faster or 'better'
body: <p>I have a loop that reads through a lot of strings, each string containing information split by a char (¥).
  For this loop, i only really need the end value, which i know the index of. I am wondering if it is better to use string.split, or to use substring.lastindexof.</p>
  
  <p>If it helps, the index for split is 8.</p>
  
  <p>Which would be faster.
  Also, does my choice of char have any influence on the split? (¥ vs ` vs " for example) </p>
  
  <p>Thanks.</p>
