C＃表单读取textBox1所有行并删除给定路径？

Question

美好的一天！

我正在尝试创建一个C＃Forms应用程序，用户在其中选择带有FolderDialog的目录，并在textBox1读取后将路径保存在list.txt文件中。在list.txt中，用户可以添加和删除路径。

代码段：

private void Form1_Load(object sender, EventArgs e)
        {
            textBox1.Lines = System.IO.File.ReadAllLines(fileName);
        }
string fileName = Environment.CurrentDirectory + @"/etc/list.txt";

       private void LoadTextboxes()
        {
            string[] loadedLines = System.IO.File.ReadAllLines(Environment.CurrentDirectory + @"/etc/list.txt");

            int index = 0;

            int n = int.Parse(loadedLines[index]);
            string[] lines = new string[n];
            Array.Copy(loadedLines, index + 1, lines, 0, n);
            textBox1.Lines = lines;
        }       
private void DeleteFilesFromDirectory(string directoryPath)
        {
            DirectoryInfo d = new DirectoryInfo(directoryPath);

            foreach (FileInfo fi in d.GetFiles())
            {
                fi.Delete();
            }

            foreach (DirectoryInfo di in d.GetDirectories())
            {
                DeleteFilesFromDirectory(di.FullName);

                di.Delete();
            }
        }

private void button1_Del(object sender, EventArgs e)
        {
            DeleteFilesFromDirectory(textBox1.Text);
        }   

list.txt格式：

C:/downloads
F:/doc/scan
D:/etc

t仅删除子文件夹和文件很重要，但必须保留根文件夹。到目前为止，我已经完成了对c＃的微弱知识，现在我已经被困了很长时间了。 DeleteFilesFromDirectory仅删除textBox1的第一行。

如何使DeleteFilesFromDirectory读取并删除textBox1中的所有行？

检查一下，我测试了它。

  //put all paths in array reading line by line
  string[] paths = System.IO.File.ReadAllLines(@"path-to\list.txt");

  //get line by line paths
  foreach (string path in paths)
  {
        if (Directory.Exists(path))
        {
            //deletes all files and parent
            //recursive:true, deletes subfolders and files
            Directory.Delete(path, true);
            //create parent folder
            Directory.CreateDirectory(path);
        }

   }//end outer for
