title: How to get the members of the group in Tridion
body: <p>With the help of event handler i am getting the id of the user who have finished the Workflow activity.</p>
  
  <p>For getting the Id i am writing like: </p>
  
  <p><code>foreach(var user  in activity.Performers)</code></p>
  
  <p><code>userId=user.Title.ToString();</code></p>
  
  <p>Now, similarly how can i get the members of the group(their id's) to which the user belongs.</p>
