title: Get character position in StringBuilder when using contains
body: <p>Been looking high and low but couldn't find how to do it. </p>
  
  <p>I'd like to do the following</p>
  
  <p>I'm trying to get the second element from converted ToString returnCode 
  for example: A1235 is returnCode. 
  I'm trying to get the "1" </p>
  
  <p>edit: Guys. It can contain two "1"s but not on the second position of the string. I need an if statement that does xyz IF the second character of returnCode is 1. Don't think "Char" is going to work. </p>
  
  <pre><code>StringBuilder matchCode = new StringBuilder();
  //returnCode is a stringbuilder type variable. 
  
  if (returnCode.ToString().charAt(1).Contains("0"))
  {
      matchCode.AppendLine("Match Confidence Level: 0 (Low Confidence)");
  }
  </code></pre>
