How to pass a arraylist in an oracleparameter array

I have an oracleParameter array that I add parameters to. Usually this works fine if I put in a single value. In this case I am trying to push in an array so that I can complete a bulk insert. My co-worker has successfully done this, but not with a oracleparameter array, onlly doing it like cmd.parameter... My code is attached, hopefully, I can use this otherwise is there an alternative that doesn't involve splitting strings in my procedure?
namespace CallOptionsAvailability
    public class CallOption

        public DAL dataAccessOPR;
        public DAL dataAccessTrades;
        public validate valid;
        DataSet ds;
        public DataTable dt = new DataTable();

        public const string opr = "opr";
        public const string trades = "trades";

        public int ContractId;
        public string ProductName;
        public string CallOptionName;
        public string CounterNotification;
        public string CounterEmail;
        public string EMONotification;
        public string EMOEmail;
        public string TradesNo;
        public string DefaultOptionVolume;
        public string PORAvailability;
        public string MW;
        public string AdditionalMW;
        public string SellerAvailabilityBy;
        public string EMOStrikeBy;
        public string MinRunTime;
        public string MinDownTime;
        public string StartsPerDay;
        public string EMOIntradayChange;
        public string MinStarts;
        public string MaxStarts;
        public string StartCharge;
        public string Comments;

        //lists for database bulk inserts.
        public List<string> LProductName = new List<string>();
        public List<string> LCallOptionName = new List<string>();
        public List<string> LCounterNotification = new List<string>();
        public List<string> LCounterEmail = new List<string>();
        public List<string> LEMONotification = new List<string>();
        public List<string> LEMOEmail = new List<string>();
        public List<string> LTradesNo = new List<string>();
        public List<string> LDefaultOptionVolume = new List<string>();
        public List<string> LPORAvailability = new List<string>();
        public List<string> LMW = new List<string>();
        public List<string> LAdditionalMW = new List<string>();
        public List<string> LSellerAvailabilityBy = new List<string>();
        public List<string> LEMOStrikeBy = new List<string>();
        public List<string> LMinRunTime = new List<string>();
        public List<string> LMinDownTime = new List<string>();
        public List<string> LStartsPerDay = new List<string>();
        public List<string> LEMOIntradayChange = new List<string>();
        public List<string> LMinStarts = new List<string>();
        public List<string> LMaxStarts = new List<string>();
        public List<string> LStartCharge = new List<string>();
        public List<string> LComments = new List<string>();

        public OracleParameter[] parms;

        private void createOracleParms()
            parms = new OracleParameter[2]
                new OracleParameter("v_Contract_Id", ContractId),
                new OracleParameter("v_Name", LProductName)

        public void InsertCallOptions()
            //Creates a list<> for each sql parameter.

            dataAccessOPR = new DAL(opr);
            dataAccessOPR.executeNonQuery("CALL_OPTION_AVAILABILITY", parms);

You should create array parameter like this:

OracleParameter p = new OracleParameter("v_Name", OracleDbType.Varchar2);
p.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
p.Size = LProductName.Count;
p.Value = LProductName.ToArray();

Open in new window

You can set p.ArrayBindSize is you want set up strings lenth.

You should also create db procedure to bulk insert with array parameter, ie:
 TYPE tt_string is table of varchar(500) index by binary_integer;

PROCEDURE bulk_save(v_Name IN tt_string) IS
FORALL i IN 1 .. v_Name.COUNT
	INSERT INTO tab (name)

tt_string is type from my previous comment.
