  <pre><code>public ActionResult HolidayIndex()
  {
      IEnumerable&lt;HOLIDAY_MASTER&gt; hdms = null;
      hdms = db.HOLIDAY_MASTER.ToList().Where(h =&gt; h.HOLIDAY_NAME.Except("Sunday") &amp;&amp; h.HOLIDAY_NAME.Except("Saturday") &amp;&amp; h.HOLIDAY_DEL.Equals(0) &amp;&amp; h.REGION_ID.Equals(RegionID)).OrderBy(h =&gt; h.DOH);
      return PartialView("HolidayIndex", hdms);           
  }
  </code></pre>
  
  <p>Error shows under <code>h.HOLIDAY_NAME.Except("Sunday") &amp;&amp; h.HOLIDAY_NAME.Except("Saturday")</code>.</p>
  
  <p>Actually, what I want is need to fetch all the Holyday_Names which is not equal to Saturday and Sunday.</p>
