Answer 1

This should answer the question. I've ignored the issue of going through subdirectories, I'm assuming you have that figured out.

Of course, you don't need to have a seperate method for this, but you might find it a useful place to also verify the path is valid, and deal with the other exceptions that you could encounter when calling GetFiles().

Hope this helps.

private string[] GetFiles(string path)
{
    string[] files = null;
    try
    {
       files = Directory.GetFiles(path);
    }
    catch (UnauthorizedAccessException)
    {
       // might be nice to log this, or something ...
    }

    return files;
}

private void Processor(string path, bool recursive)
{
    // leaving the recursive directory navigation out.
    string[] files = this.GetFiles(path);
    if (null != files)
    {
        foreach (string file in files)
        {
           this.Process(file);
        }
    }
    else
    {
       // again, might want to do something when you can't access the path?
    }
}
