指数超出范围.必须非负且小于集合的大小.参数名称:index SQLite

目前我得到一个错误，当试图建立我的SQL表的错误是上面的标题"索引超出范围。必须非负且小于集合的大小。参数名称:index"我不明白为什么它抛出这个，但代码本身似乎很好…

static void Main(string[] args)
    {
        ServiceReference1.ControlPumpsClient WCFSQL = new SQLserver.ServiceReference1.ControlPumpsClient();
        string[] SQLData = new string[6];
        while (WCFSQL.getData()[0] == null) { }
        if (WCFSQL.getData()[0] != null)
        {
            SQLData = WCFSQL.getData();
        }

        SQLiteConnection myConnection = new SQLiteConnection("Data source=test.db; Version=3;");
        myConnection.Open();
        /// If this is not the first time the program has run, 
        /// the table 'cars' will already exist, so we will remove it
        SQLiteCommand tableDropCommand = myConnection.CreateCommand();
        tableDropCommand.CommandText = "drop table Records";
        try
        {
            tableDropCommand.ExecuteNonQuery();
        }
        catch (SQLiteException ex) // We expect this if the table is not present
        {
            Console.WriteLine("Table 'Records' does  not exist");
        }
        /// Now create a table called 'records'
        SQLiteCommand tableCreateCommand = myConnection.CreateCommand();
        tableCreateCommand.CommandText = "create table Records (ID int, FuelType varchar(10), Price float, TankVolume int)";
        tableCreateCommand.ExecuteNonQuery();
        /// Now insert some data.
        /// First, create a generalised insert command
        SQLiteCommand insertCommand = myConnection.CreateCommand();
        insertCommand.CommandText = "insert into Records (ID, FuelType, Price, TankVolumes) values (@id, @fueltype, @price, @volume)";
        insertCommand.Parameters.Add(new SQLiteParameter("@id"));
        insertCommand.Parameters.Add(new SQLiteParameter("@fueltype"));
        insertCommand.Parameters.Add(new SQLiteParameter("@price"));
        insertCommand.Parameters.Add(new SQLiteParameter("@tankvolume"));
        addSQL(insertCommand, int.Parse(SQLData[0]), SQLData[1], float.Parse(SQLData[2]), double.Parse(SQLData[3]));
        /// Now, create a comand to read from the database;
        SQLiteCommand listAllRecordsCommand = myConnection.CreateCommand();
        listAllRecordsCommand.CommandText = "select * from Records";
        SQLiteDataReader reader = listAllRecordsCommand.ExecuteReader();
        /// Iterate over the results and print them
        while (reader.Read())
        {
            StringBuilder sb = new StringBuilder();
            sb.Append(reader["ID"] + ",");
            sb.Append(reader["FuelType"] + ",");
            sb.Append(reader["Price"] + ",");
            sb.Append(reader["Volumes"] + ",");
            Console.WriteLine(sb.ToString());
        }
        myConnection.Close();
        /// Wait for a keypress
        Console.ReadLine();
    }
    public static void addSQL(SQLiteCommand insertCommand, int pumpID, string fuel, float price, double volume){
         /// Now, set the values for the insert command and add two records
        insertCommand.Parameters["@id"].Value = pumpID;
        insertCommand.Parameters["@fueltype"].Value = fuel;
        insertCommand.Parameters["@price"].Value = price;
        insertCommand.Parameters["@volume"].Value = volume;
        insertCommand.ExecuteNonQuery();
    }
}

错误发生在用黄色突出显示的这一行

insertCommand.Parameters["@volume"].Value = volume;
