title: Match single character in .net regex
body: <p>According to the <a href="http://msdn.microsoft.com/en-us/library/az24scfc(v=vs.110).aspx" rel="nofollow">MSDN documentation</a>, the <code>.</code> character </p>
  
  <blockquote>
    <p>Matches any single character except \n.</p>
  </blockquote>
  
  <p>In this case, why does this regex not match?:</p>
  
  <pre><code>Regex.IsMatch("c",@"[.]")
  </code></pre>
