Is there a way to retrieve the entire line that the FileHelpers Engine is parsing

We are using FileHelpers to parse a text file into numerous entities, based on the first character in the line. Each entity is then stored in a particular database table. We would also like to store each input string, as a whole, in addition to the parsed fields.

Is there a way to capture the input line, before it is parsed into the individual fields of the entity?

You can use events to get the full line, BeforeReadRecord or AfterReadRecord have an argument that contains the property RecordLine

Here is an example: https://www.filehelpers.net/example/EventsAndNotification/ReadEvents/

[FixedLengthRecord(FixedMode.AllowVariableLength)]
[IgnoreEmptyLines]
public class OrdersFixed
{
    [FieldFixedLength(7)]
    public int OrderID;

    [FieldFixedLength(8)]
    public string CustomerID;

    [FieldFixedLength(8)]
    public DateTime OrderDate;

    [FieldFixedLength(11)]
    public decimal Freight;
}

public override void Run()
{
    var engine = new FileHelperEngine<OrdersFixed>();
    engine.BeforeReadRecord += BeforeEvent;
    engine.AfterReadRecord += AfterEvent;

    var result = engine.ReadFile("report.inp");

    foreach (var value in result)
        Console.WriteLine("Customer: {0} Freight: {1}", value.CustomerID, value.Freight);

}

private void BeforeEvent(EngineBase engine, BeforeReadEventArgs<OrdersFixed> e)
{
     Console.Write(e.RecordLine)
}


private void AfterEvent(EngineBase engine, AfterReadEventArgs<OrdersFixed> e)
{
     Console.Write(e.RecordLine)
}
