FileHelpers and CSV: what to do when a record can expand unbounded, horizontally

Question

I\'m trying to parse this type of CSV file with FileHelpers:

Tom,1,2,3,4,5,6,7,8,9,10
Steve,1,2,3
Bob,1,2,3,4,5,6
Cthulhu,1,2,3,4,5
Greg,1,2,3,4,5,6,7,8,9,10         


        

Answer 1

You can use an Array Field and the library will do the work:

[DelimitedRecord(",")]
public class MyRecord
{
    public string Name;

    public int[] Values;
}

You can even use [FieldArrayLength(2, 8)]

[DelimitedRecord(",")]
public class MyRecord
{
    public string Name;

    [FieldArrayLength(2, 8)]
    public int[] Values;
}

The set the min/max number of values

I strongly recomend to download the last version of the library from here:
