title: Add Id or other attributes to ASP.NET MVC 3 Html Helper Textbox
body: <p>How can I add attributes to a html helper textbox.</p>
  
  <p>I've tried this:</p>
  
  <pre><code>@Html.TextBox("username", new { id = "username" })
  </code></pre>
  
  <p>This seems to put 'id=username' in the value field of the textbox. I want to add an Id to my textbox.</p>
  
  <p>Thanks.</p>
