LINQ question - reading structured files

[Griff]

Hi

Is it possible to query a structured file that is a FIXED WIDTH file rather
than a delimited file?

I think it would be great to first define how many columns one is expecting
and the width (in characters) of each column, and then to be able to write
WHERE clauses in the Linq query e.g. "where field(2) = [mySearchTerm]".

But I can't find any examples on the web of how to achieve this...

Thanks

Griff
