मुझे एकाधिक रिकॉर्ड्स को एकाधिक कैसे सम्मिलित करना चाहिए?

static void InsertSettings(IEnumerable<Entry> settings) {
    using (SqlConnection oConnection = new SqlConnection("Data Source=(local);Initial Catalog=Wip;Integrated Security=True")) {
        oConnection.Open();
        using (SqlTransaction oTransaction = oConnection.BeginTransaction()) {
            using (SqlCommand oCommand = oConnection.CreateCommand()) {
                oCommand.Transaction = oTransaction;
                oCommand.CommandType = CommandType.Text;
                oCommand.CommandText = "INSERT INTO [Setting] ([Key], [Value]) VALUES (@key, @value);";
                oCommand.Parameters.Add(new SqlParameter("@key", SqlDbType.NChar));
                oCommand.Parameters.Add(new SqlParameter("@value", SqlDbType.NChar));
                try {
                    foreach (var oSetting in settings) {
                        oCommand.Parameters[0].Value = oSetting.Key;
                        oCommand.Parameters[1].Value = oSetting.Value;
                        if (oCommand.ExecuteNonQuery() != 1) {
                            //'handled as needed, 
                            //' but this snippet will throw an exception to force a rollback
                            throw new InvalidProgramException();
                        }
                    }
                    oTransaction.Commit();
                } catch (Exception) {
                    oTransaction.Rollback();
                    throw;
                }
            }
        }
    }
}
