>>>This kinda works, but I'm copying everything twice. Is there a way to do this by copying only once?

Linq is designed to work with one dimensional IEnumerable structures. It probably won't work for you unless you can work with jagged arrays/lists. You may find some helpful suggestions at http://stackoverflow.com/questions/9774901/how-to-convert-list-of-arrays-into-a-multidimensional-array.

As far as copying everything twice, is there a reason that you need to call the ResizeArray function? Why not just set lines = work2?
