Could also user dynamic keyword for converting any data

Code from @Lin

public FileStreamResult  ExportPayments()
{
    var result = WriteCsvToMemory(_commonService.GetPayments()()); 
    var memoryStream = new MemoryStream(result);
    return new FileStreamResult(memoryStream, "text/csv") { FileDownloadName = "export.csv" };
}


public byte[] WriteCsvToMemory(dynamic records)
{
    using (var memoryStream = new MemoryStream())
    using (var streamWriter = new StreamWriter(memoryStream))
    using (var csvWriter = new CsvWriter(streamWriter))
    {
        csvWriter.WriteRecords(records);
        streamWriter.Flush();
        return memoryStream.ToArray();
    }
}
