Tell me how to implement the tree output folders and subfolders?

 class Program { private static void FilesandFolders(string Path1, int down = 0) { string[] directory = Directory.GetDirectories(Path1); string[] set = Directory.GetFiles(Path1); try { foreach (string file in set) { Console.WriteLine(new string(' ', down) + " └ " + Path.GetFileNameWithoutExtension(file)); } foreach (string file in directory) { Console.WriteLine(new string(' ', down) + " + " + Path.GetFileNameWithoutExtension(file)); FilesandFolders(file, down++); } } catch { } } static void Main() { Console.WriteLine("Программа выводит каталог папок и файлов в заданной папке."); Console.Write("Введите имя папки: "); string path = Console.ReadLine(); Console.WriteLine(" " + path); FilesandFolders(path, 0); Console.Read(); } 

Well, that's where it is, just put the loop in another one and that's it:

  private static void SearchFoldersAndFiles(String path, DirectoryInfo parent = null, String space = null) { DirectoryInfo directoryInfo = new DirectoryInfo(path); foreach (var item in directoryInfo.GetDirectories()) { Console.WriteLine($"\t{space}+{item.Name}"); SearchFoldersAndFiles(path + @"\" + item.Name, item.Parent, "\t"); foreach (var file in item.GetFiles()) { Console.WriteLine($"\t\t└{file.Name}"); } Console.WriteLine(); } } static void Main(string[] args) { Console.WriteLine("Программа выводит каталог папок и файлов в заданной папке."); Console.Write("Введите имя папки: "); string path = Console.ReadLine(); Console.WriteLine(" " + path); SearchFoldersAndFiles($@"{path}", null); Console.ReadKey(); } 

PS you can still play around with the output)
