Retrieve a Saved Search

I'm having trouble retrieving the actual data of a saved search. Here is a sample of my code:

// create search object
TransactionSearchAdvanced customSearch = new TransactionSearchAdvanced();

//set saved search id
customSearch.savedSearchId = "3667";

//perform the search
SearchResult resp = _service.search(customSearch);               
Status status = resp.status;
  if (status.isSuccess.Equals(true))
  {
  MessageBox.Show(recordList.Length.ToString());
   }


At this point I'm just trying to validate the Length of the recordList in the response. When I try to reference any part of the "resp.recordList" I get the "Object reference not set to an instance of an object" error.

The strange part is that resp.totalRecords gives me the correct response of 30 records.
