How to filter files from FileSystem.GetFiles using LINQ?

Question

I want to get some files by some conditions, i can get the files by the file type, the code is below.
Dim wildcards As String() = {".mp3", ".ape"}
Dim ListFiles = FileIO.FileSystem.GetFiles("G:\Music", FileIO.SearchOption.SearchAllSubDirectories, wildcards)

Now I want to exclude the hidden, system properties and 0-byte files, how to add the LINQ express?
My .NET Framework version is 4.6, so I cannot use the Directory.EnumerateFiles method, thank you.

Answer 1

You can do something like this =>

       Dim ListFiles = FileIO.FileSystem.GetFiles("G:\Music", FileIO.SearchOption.SearchAllSubDirectories, wildcards).Where(Function(f) (FileLen(f) > 0 AndAlso (File.GetAttributes(f) And FileAttributes.Hidden) <> FileAttributes.Hidden AndAlso (File.GetAttributes(f) And FileAttributes.System) <> FileAttributes.System))

Answer 2

For dynamic

Add your logic to determine the rules.

Dim result As IEnumerable(Of String) = ListFiles.Where(Function(item) FileLen(item) > 0)
result = result.Where(Function(f) (File.GetAttributes(f) And FileAttributes.Hidden) <> FileAttributes.Hidden)
result = result.Where(Function(f) (File.GetAttributes(f) And FileAttributes.System) <> FileAttributes.System)
