Good day!

I'm trying to create a C # Forms app where user chooses directories with FolderDialog and paths are saved in list.txt file after read by textBox1.
In list.txt user can add and delete path.

code snippet:

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 format:

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

t is important to delete only the sub folders and files but root folders must remain.
So far I have been done with my weak knowledge of c# and and now I'm stuck for a long time.
DeleteFilesFromDirectory only deletes the first line of textBox1.

How to make DeleteFilesFromDirectory read and delete all lines from textBox1?

  If given path is F:/doc/scan, then need to be wiped everything under folder scan, but leave root folder scan empty

Check this I tested it.

 //put all paths in array reading line by line
 string[] paths = System.IO.File.ReadAllLines(@"path-tolist.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
