Filter hidden files

[David Brenchley]

I want to be able to display only files that are not set to hidden by the OS.

How do I filter files that are hidden?  I'm using the filter example, but it looks like there is no attribute or property of Hidden.

Hi David,

In order to filter the hidden files, the ResolveDirectory() method should be overriden. You can check the attributes of a file using FileInfo Class, e.g:

public override DirectoryItem ResolveDirectory(string path)
{
    // Update all file items with the additional information (date, owner)
    DirectoryItem oldItem = base.ResolveDirectory(path);

    List<FileItem> visibleFiles = new List<FileItem>();


    foreach (FileItem fileItem in oldItem.Files)
    {
        // Get the information from the physical file
        FileInfo fInfo = new FileInfo(Context.Server.MapPath(VirtualPathUtility.AppendTrailingSlash(oldItem.Path) + fileItem.Name));
        if ((fInfo.Attributes & FileAttributes.Hidden) != FileAttributes.Hidden)
        {
            visibleFiles.Add(fileItem);
        }
    }

    DirectoryItem result = new DirectoryItem(oldItem.Name, oldItem.Location, oldItem.FullPath, oldItem.Tag, oldItem.Permissions, visibleFiles.ToArray(), oldItem.Directories);
    return result;
}

I hope this helps.

I know this was form years ago but i get a System.StackOverflowException at -

DirectoryItem oldItem = base.ResolveDirectory(path);

Hi Paul,

Can you provide a little more details on the exact scenario in which the issue occurs? Are you implementing a FileSystem or FileBrowser content provider? Would it be possible to send us an isolated version of your code, so we can examine the problematic behavior and configuration on our side?
