Array which Pages to Disk

Question

Does anyone know of a .NET array class/library which will page its contents out to disk?

The idea is to be able to use it as a normal array but the class uses less RAM

Answer 1

I found this solution in VB of a file-based array: http://www.vbforums.com/showthread.php?t=504649

But it seems hacky... Still looking for another implementation.
