title: Most efficient way to convert this string to DateTime
body: <p>I receive DateTime in this format => yyyyMMddHHmmss e.g. 20160214204032</p>
  
  <p>Due to its somewhat unique format, I can't just use Convert.ToDateTime -- I tried, it didn't work.</p>
  
  <p>It's easy enough to create a helper method that would parse the components of this date e.g </p>
  
  <p><code>var year = myString.Substring(0,4);</code></p>
  
  <p>but I'm concerned that this may have poor performance.</p>
  
  <p>Can anyone think of a better way to convert a string in this format to DateTime?</p>
