 4   {
 5     try
 6     {
 7       action(client);
 8       client.Close();
 9     }
10     catch (CommunicationException)
11      {
12       client.Abort();
13       throw;
14     }
15     catch (TimeoutException)
16     {
17       client.Abort();
18       throw;
19     }
20     catch (Exception)
