Ignore case with v12 of PrepareHeaderForMatch in Visual Basic

[jorgeshimada]

I'm trying to implement to ignore the header name case, using CSVHelper 12 in Visual Basic.
The code below didn't work. Can every explain or show me how to do it

Using csv As New CsvReader(Reader)
csv.Configuration.PrepareHeaderForMatch = (String header) >= header.ToUpper()
End Using

Any help will be appreciate. Thanks in advance

Try this

csv.Configuration.PrepareHeaderForMatch = Function(header, field) header.ToUpper()
