Answer 1

Here's a solution completely without LINQ:

public static string[] GetHierarchy(this string path)
{
    var res = path.Split('.');
    string last = null;
    for (int i = 0; i < res.Length; ++i)
    {
        last = string.Format("{0}{1}{2}", last, last != null ? "." : null, res[i]);
        res[i] = last;
    }
    return res;
}
