I will create a CSV Import for invoices for my mother, so I have create a Interface that read a CSV file, and for each line in the CSV the values to a List<List<string>>.
Now is the Problem the following:
ABC; 1300; Customer 1; Product1; Product Description; 0; 0; 0
ABC; 1300; Customer 1; Product2; Product Description; 1; 2; 0
The Second value is the invoice number and the 4-5 values are for the invoice "lines". I have really no Idea how to solve this that all line with the same value as second go though the same file. Maybe you can help ?
