title: where not in () statement with lambda
body: <p>Does anyone any idea how can we use where not in() statement with lambda?</p>
  
  <pre><code>this is where id in() statement
  
  public List&lt;abc&gt; GetList(List&lt;string&gt; ID)
  {
  return db.abcs.Where(a =&gt; ID.Contains(a.id)).ToList&lt;abc&gt;();
  }
  </code></pre>
  
  <p>I'd like to find how cloud it be opposite.   "where id not in..."</p>
