title: Get records of last week adding by datetime in database
body: <p>I'm using asp.net MVC in my project. My database table includes some records. The table has datetime column for records. I want to get records of last week adding. So the <code>LastlyRecords</code> is:</p>
  
  <pre><code>DateTime.Now = 04.04.2015
  LastWeekDateTime = 28.04.2015
  LastWeekDateTime &lt; LastlyRecords &lt; DateTime.Now
  </code></pre>
