Using FileSystem.GetFiles and regular expression ?

[graphicsxp]

Hi,
I need to find recursively all the files which have extension .mdb so I
did that:

files = My.Computer.Fil eSystem.GetFile s("C:\Databases ",
FileIO.SearchOp tion.SearchAllS ubDirectories, "*.mdb")

Now I want to exclude the file which contain the strings "_Backup" or
"basket" in the filename (and still filtering on *.mdb). I suppose I
should use regular expressions, but I can't figure out what the
expression should look like. Can you help ?

Thanks
