Question

I am using the CSVHelper Component from NuGet. I have all of my data exporting successfully. However, I have several fields that are boolean type and return “true”/”false” to the csv file. My project requires that instead I output either “1” or “0” instead of “true”/”false”. What is the easiest way to achieve this?

    var AllRecords = surveyResponseRepository.Get()
                    .Where(r => r.ProgramId == ProgramId);

    string uniqueID = Guid.NewGuid().ToString(); 

    var appData = Server.MapPath("~/CsvExport/" + uniqueID + ".csv");

    using (var csv = new CsvWriter(new StreamWriter(appData)))

    {
        csv.Configuration.HasHeaderRecord = true;
        csv.Configuration.Delimiter = ',';
        csv.WriteRecords(AllRecords);
    }

I believe you could inherit CsvWriter and override WriteField to something like this:

    public override void WriteField( string field )
    {
        if (field.ToLower() == bool.TrueString.ToLower())
             field = "1";
        if (field.ToLower() == bool.FalseString.ToLower())
             field = "0";
        base.WriteField(field);
    }
