string[,] lines2 = (string[,]) work2.Clone();

But can I ask what you subsequently do with the array ?

Thank you very much; Let me try that.

Well the file that gets read by the Linq is just a csv without headers, 13 string fields really. I just need to read it in, and use some fields of it, so I thought I'd use array[1] for the second field and so on.
