title: Why list item is zero?
body: <p>I have a list which contains following items:  </p>
  
  <blockquote>
    <p>Bundled/releases/US---NL<br>
    Bundled/releases/UK---US   </p>
  </blockquote>
  
  <p>I want  search for substring ("US" or "UK") in list item.  </p>
  
  <pre><code>var testVar = (from r in ghh
      where (r.Substring(r.LastIndexOf('/') + 1, 
                         (r.Length - (r.IndexOf("---")    + 3)))) == "US"
      select r).ToList();
  
  if ( testVar != null)
  {
      //print item is present
  }
  </code></pre>
  
  <p>(<code>ghh</code> is list name)</p>
  
  <p>But <code>testVar</code> is always showing <code>null</code>. Why?</p>
