using (new CallerImpersonationScope(service, userId))
{
   // Display information about the logged on user.
   Guid effectiveUserId = ((WhoAmIResponse)service.Execute(new WhoAmIRequest())).UserId;
   SystemUser systemUser = (SystemUser)service.Retrieve("systemuser", effectiveUserId, 
       new ColumnSet(new string[] {"firstname", "lastname"}));
   Console.WriteLine("Logged on user is {0} {1}.", systemUser.FirstName, systemUser.LastName);
}
