C# Best way to get folder depth for a given path?

Question

I\'m working on something that requires traversing through the file system and for any given path, I need to know how \'deep\' I am in the folder structure. Here\'s what I\'m cu

Answer 1

I'm always a fan the recursive solutions. Inefficient, but fun!

public static int FolderDepth(string path)
{
    if (string.IsNullOrEmpty(path))
        return 0;
    DirectoryInfo parent = Directory.GetParent(path);
    if (parent == null)
        return 1;
    return FolderDepth(parent.FullName) + 1;
}

I love the Lisp code written in C#!

Here's another recursive version that I like even better, and is probably more efficient:

public static int FolderDepth(string path)
{
    if (string.IsNullOrEmpty(path))
        return 0;
    return FolderDepth(new DirectoryInfo(path));
}

public static int FolderDepth(DirectoryInfo directory)
{
    if (directory == null)
        return 0;
    return FolderDepth(directory.Parent) + 1;
}

Good times, good times...
