title: String manipulation, removing last few characters
body: <p>When I try to remove the last few characters of a string, I get an index out of range error.  I am using the following to remove the characters from the end of the string:</p>
  
  <pre><code>objJSONStringBuilder.Remove(objJSONStringBuilder.Length - 1, 6)
  </code></pre>
  
  <p>The string has <code>&lt;hr /&gt;</code> at the end which I want to remove.</p>
