title: @Html.ActionLink adds "?Length=4" in links
body: <p>I use</p>
  
  <pre><code> @Html.ActionLink("Read More", "About", "Home", new {@class="button"}) 
  </code></pre>
  
  <p>in my Asp.NET MVC web site, but as result my link looks like this,</p>
  
  <p><code>http://localhost:43988/Home/About?Length=4</code>.</p>
  
  <p>Why I get this part <code>?Length=4</code> in my links?</p>
