title: Strip double quotes from a string in .NET
body: <p>I'm trying to match on some inconsistently formatted HTML and need to strip out some double quotes.</p>
  
  <p>Current:</p>
  
  <pre><code>&lt;input type="hidden"&gt;
  </code></pre>
  
  <p>The Goal:</p>
  
  <pre><code>&lt;input type=hidden&gt;
  </code></pre>
  
  <p>This is wrong because I'm not escaping it properly:</p>
  
  <blockquote>
    <p>s = s.Replace(""","");</p>
  </blockquote>
  
  <p>This is wrong because there is not blank character character (to my knowledge):</p>
  
  <pre><code>s = s.Replace('"', '');
  </code></pre>
  
  <p>What is syntax / escape character combination for replacing double quotes with an empty string?</p>
