C# - Get a list of files excluding those that are hidden

Question

Directory.GetFiles() returns all files, even those that are marked as hidden. Is there a way to get a list of files that excludes hidden files?

Answer 1

This should work for you:

DirectoryInfo directory = new DirectoryInfo(@"C:\temp");
FileInfo[] files = directory.GetFiles();

var filtered = files.Select(f => f)
                    .Where(f => (f.Attributes & FileAttributes.Hidden) == 0);

foreach (var f in filtered)
{
    Debug.WriteLine(f);
}

Answer 2

Using .NET 4.0 and Directory.EnumerateDirectories, you could use this construct :

var hiddenFilesQuery = from file in Directory.EnumerateDirectories(@"c:\temp")
                       let info = new FileInfo(file)
                       where (info.Attributes & FileAttributes.Hidden) == 0
                       select file;

This is basically the same as the other answer, except Directory.EnumerateDirectories is a bit more lazy. This is not very useful if you enumerate everything, though.

(The let is here to have the query a but more readeable).
