title: Get 16 bit hash of a string in C#
body: <p>I have seen the C# function <code>String.GetHashCode();</code> is used to return a 32bit integer hash of a string.</p>
  
  <p>I want to generate a simple 16bit hash of a string value.  The string will always be 9 characters long.</p>
  
  <p>Can anyone assist?</p>
  
  <p>Thanks</p>
