从完整文件路径c#获取文件夹名称

Question

我正在尝试找出文件夹的完整目录。例如Folder\TopLevel\Sub-Directory 及以后。但是，顶级文件夹的命名方式完全不同，例如顶级 1、顶级 2.. 它们都有不同的子目录等。即使所有文件夹的名称都不同，我如何才能一次显示所有目录。谢谢！

我的代码：

using System;
using System.IO;

namespace FolderStructure
{
public class Folder
{
    static void Main(string[] args)
    {
        string[] fileArray = Directory.GetDirectories("H:\Folder\TopLevel\Sub-Directory\");
        for (int i = 0; i < fileArray.Length; i++)
        {
            Console.WriteLine(fileArray[i]);
        }
        Console.ReadLine();
    }
  }
}

编辑：

此图显示了它如何只显示到子文件夹。但是，我想知道子文件夹内及以后的内容。

这是我几周前写的一个程序，它将结果保存到 xml

        const string FOLDER = @"c:\temp";
        static XmlWriter writer = null;
        static void Main(string[] args)
        {
            XmlWriterSettings settings = new XmlWriterSettings();
            settings.Indent = true;

            writer = XmlWriter.Create(FILENAME, settings);
            writer.WriteStartDocument(true);

            DirectoryInfo info = new DirectoryInfo(FOLDER);
            WriteTree(info);

                writer.WriteElementString("Error",errorMsg);
            }

            if (fileInfo != null)
            {
                foreach (FileInfo finfo in fileInfo)
                {
                    try
                    {
                        writer.WriteStartElement("File");
                        writer.WriteAttributeString("name", finfo.Name);
                        writer.WriteAttributeString("size", finfo.Length.ToString());
