Is random access possible with My.Computer.FileSystem?

FileOpen(FNum, FName, OpenMode.Random, OpenAccess.Read, OpenShare.Shared, Len(FRec))

After converting this program to VS dotNet 2005, I see several notes in the MSDN documentation and in the conversion log that say that My.Computer.FileSystem offers better performance than FileOpen, but I don't see a random access example, and I don't see My.Computer.FileSystem methods that correspond to all the older functions.

Is random access possible with My.Computer.FileSystem? If so, will someone share an example that reads and writes to a random access file with My.Computer.FileSystem?

TIA
