NamedIndexes and ReadingContext Replacement?

[dprice]

After upgrading from v12 to v26, I lost the ability to get detailed information about a failing CSV read. This is a sample of what I was doing before:

Reader.Configuration.ReadingExceptionOccurred = ex =>
{
    var fieldNames = ex.ReadingContext.NamedIndexes.Keys.ToList();
    var fieldName = fieldNames.Any() ? fieldNames[ex.ReadingContext.CurrentIndex] : "Unknown";
    var msg =
        $"Unable to convert field '{fieldName}' with value '{ex.ReadingContext.Record[ex.ReadingContext.CurrentIndex]}' on row {ex.ReadingContext.Row}. Actual data: {ex.ReadingContext.RawRecord}. ";
    msg += $"Additional Information: {ex}";
    _logger.Error(msg);
    
    return false;
};

I've updated this to use Exception.Context for ReadingContext but I cannot get the same level of detail that I had before. Where did these properties migrate to?

They're internal to classes. Having them globally available like that slowed reading down significantly.

Most of that information should appear in the exception message now though.
