Retrieving files recursively: skip files / directories that cannot be read?

I want to get all the files in a directory in an array (including files in subfolders)

string[] filePaths = Directory.GetFiles(@"c:\",SearchOption.AllDirectories);

The problem with this: if an exception is thrown, the whole command stops. Is there a better way to do this so that if the folder cannot be accessed, it just skips it?

You will probably have to type yourself a bit and then write a directory move, like this one:

    public static string[] FindAllFiles(string rootDir) {
        var pathsToSearch = new Queue<string>();
        var foundFiles = new List<string>();

        pathsToSearch.Enqueue(rootDir);

        while (pathsToSearch.Count > 0) {
            var dir = pathsToSearch.Dequeue();

            try {
                var files = Directory.GetFiles(dir);
                foreach (var file in Directory.GetFiles(dir)) {
                    foundFiles.Add(file);
                }

                foreach (var subDir in Directory.GetDirectories(dir)) {
                    pathsToSearch.Enqueue(subDir);
                }

            } catch (Exception /* TODO: catch correct exception */) {
                // Swallow.  Gulp!
            }
        }

        return foundFiles.ToArray();
    }

try the following:

DirectoryInfo directory = new DirectoryInfo(@"c:\");
        DirectoryInfo[] folders = directory.GetDirectories("*", SearchOption.AllDirectories);

        List<string> files = new List<string>();
        foreach (DirectoryInfo info in folders)
        {
            foreach (FileInfo file in info.GetFiles())
            {
                files.Add(file.Name);
            }
        }

or try the following:

        DirectoryInfo dirs = new DirectoryInfo(@"c:\");
        List<string> filenames = (from i in dirs.GetFiles("*", SearchOption.AllDirectories)
                                  select i.Name).ToList();

or file names without extension:

        DirectoryInfo dirs = new DirectoryInfo@"c:\");
        List<string> filenames = (from i in dirs.GetFiles("*", SearchOption.AllDirectories)
                                  select System.IO.Path.GetFileNameWithoutExtension(i.Name)).ToList();
