title: How do I find all CR+LF's in a string?
body: <p>I'm trying to replace all carrage returns with a <code>&lt;br/&gt;</code> tag in C#.  I thought this would take care of everything: </p>
  
  <pre><code>StringBuilder sb = new StringBuilder(s);
  sb.Replace(System.Environment.NewLine, @"&lt;br/&gt;");
  </code></pre>
  
  <p>But apparently not.  It doesn't seem to catch <code>CR+LF</code>.  </p>
