Как я программно возмещаю использование PayPal?

Я использовал следующий код, разграбленный в чьем-то блоге (прошу прощения за отсутствие цитирования). Он заботится о кавычках, переводе строки и запятой довольно элегантным способом, заключая в кавычки каждое значение поля.

    /// <summary>
    /// Converts the passed in data table to a CSV-style string.      
    /// </summary>

    public static string ToCSV(this DataTable table)
    {
        return ToCSV(table, ",", true);
    }
