用CoreLab.Oracle连接方式访问oracle的游标，得不到DataSet ！

 public bool RunProcedure(string ReturnParameter, CoreLab.Oracle.OracleDbType ParamType, ref DataSet Dataset, Hashtable HT, string ProcedureName)
        {            CoreLab.Oracle.OracleConnection Connection =new CoreLab.Oracle.OracleConnection();
            Connection.ConnectionString = this.DataAcc.OracleConnectionString;
            Connection.Open();            CoreLab.Oracle.OracleCommand dacommand = new CoreLab.Oracle.OracleCommand();
            dacommand.Connection = Connection;            dacommand.CommandType = CommandType.StoredProcedure;
            IDictionaryEnumerator Enumerator;
            Enumerator = HT.GetEnumerator();
            object Value = null;
            CoreLab.Oracle.OracleParameter OracleParam;
            OracleParam = dacommand.Parameters.Add(new CoreLab.Oracle.OracleParameter(ReturnParameter, ParamType));
            OracleParam.Direction = ParameterDirection.Output;            while (Enumerator.MoveNext())
            {
                Value = Enumerator.Value;
                OracleParam = dacommand.Parameters.Add(new CoreLab.Oracle.OracleParameter(Enumerator.Key.ToString(), Value));
            }            CoreLab.Oracle.OracleDataAdapter ODAdapter = new CoreLab.Oracle.OracleDataAdapter(dacommand);            try
            {
                ODAdapter.Fill(Dataset);
                Close();
                return true;
            }
            catch
            {
                Close();
                return false;
            }
            finally
            {
                HT.Clear();
                dacommand.Parameters.Clear();
            }
        }此种方式在访问System.Data.OracleClient方式下访问就可以，为什么在CoreLab.Oracle方式的时候就没有返回记录！哪位给看看
