How to avoid searching of Operating system protected files ($RECYLE.BIN) in treeview

Hi there,

Unfortunately the search options in listing files doesn't have that option, at least to my knowledge. I think you have to write your own method to achieve this. If you are in .net 4.0, you could use EnumerateDirectories. Try something like this :

private IEnumerable<DirectoryInfo> EnumerateDirectories(DirectoryInfo dir, string target)
{
    foreach (var di in dir.EnumerateDirectories("*",SearchOption.TopDirectoryOnly))
    {
        if ((di.Attributes & FileAttributes.Hidden) != FileAttributes.Hidden)
        {
            if (di.Name.EndsWith(target, StringComparison.OrdinalIgnoreCase))
            {
                 yield return di;
                 continue;
            }
            foreach (var subDir in EnumerateDirectories(di, target))
            {
                yield return subDir;
            }
        }
    }
}

and then :

DirectoryInfo dir = new DirectoryInfo(@"C:\RootDir");
var found = EnumerateDirectories(dir,"target").ToArray();

This way, if you run into a hidden directory, you stop going through sub directories. Be aware that it may to scan 'nested' directories though.

Hope this helps.
