How to get 2 level of directory?

I've a directory like this with some sub-directories :

root
    child-1
        child-1-1
            child-1-1-1
            ...
            child-1-1-n
        child-1-2
            child-1-2-1
            ...
            child-1-2-n
        ...
    child-2
        child-2-1
            child-2-1-1
            ...
            child-2-1-n
        child-2-2
            child-2-2-1
            ...
            child-2-2-n
    child-N

with this code:

var dirInfo = new DirectoryInfo(@"c:\root");
var folders = dirInfo.GetDirectories().ToList();
foreach (var item in folders)
{
  Console.WriteLine(item.Name);
}

I just get 1st levels ;

child-1
child-2
child-3
....
child-n

now I wan to get list of root directory in 2 level :

child-1
    child-1-1
    child-1-2
child-2
    child-2-1
    child-2-2
...

I think it is possible with recursive function but I'm not sure about that.

Thanks in advance.

this should help you, just specify how deep you want to go in the main method

using System;
using System.IO;
using System.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.BufferHeight = 500;
            listDirec(@"c:\program files", 1, 2);
            Console.ReadKey();
        }

        static void listDirec(string path, int start, int end)
        {
            var dirInfo = new DirectoryInfo(path);
            var folders = dirInfo.GetDirectories().ToList();

            foreach (var item in folders)
            {
                Console.WriteLine("".PadLeft(start * 4, ' ') + item.Name);

                if (start < end)
                    listDirec(item.FullName, start + 1, end);
            }
        }
    }
}
