CsvHelper set default custom TypeConverter

With CsvHelper, when I want a custom parser (for example, I want a MyBooleanConverter with the input string is \"f\" will be false, \"t\" will

Answer 1

It's also possible to have CsvHelper generate your ClassMap, at which point you can customize its handling for your members. I found this useful for getting things done in my little hobby project.

var csv = new CsvReader(streamReader, false);
var classMap = csv.Configuration.AutoMap(); // ClassMap creation

// My price data has dollar signs so those need to be stripped out before parsing to a decimal
classMap.Map(row => row.Price).ConvertUsing(row => decimal.Parse(row.GetField("Price").Replace("$", "")));

// CsvHelper doesn't support URIs so that requires help as well
classMap.Map(row => row.Source).ConvertUsing(row => new Uri(row.GetField("Source")));

var prices = csv.GetRecords();



// my DTO
class Row
{
    public decimal Price { get; set; }
    public string ManufacturerSku { get; set; }
    public string Manufacturer { get; set; }
    public Uri Source { get; set; }
    public DateTimeOffset Extraction_Time { get; set; }
}
