Directory.EnumerateFiles vs Directory.Delete

Question

Hi,

Are this code:

var dir = new DirectoryInfo(viewDeviceItem.Path);

dir.Delete(true);

Equivalent to:

using System;

using System.IO;

class Program

{

static void Main()

{

string directoryPath = @"C:\path\to\your\directory"; // Specify your directory path here

try

{

// Delete all files in the directory

foreach (var file in Directory.EnumerateFiles(directoryPath))

{

File.Delete(file);

}

// Delete all subdirectories in the directory

foreach (var subDirectory in Directory.EnumerateDirectories(directoryPath))

{

Directory.Delete(subDirectory, true); // true to delete subdirectories and files inside them

}

// Delete the directory itself

Directory.Delete(directoryPath, false); // false because we’ve already deleted the contents

Console.WriteLine("Directory and its contents have been deleted.");

}

catch (Exception ex)

{

Console.WriteLine($"An error occurred: {ex.Message}");

}

}

}

to delete a directory, the directory must be empty. so a recursive delete of files is required. your code is functionally the same, but it uses Directory.Delete() instead of recursion (so not sure the point)

the Directory.Delete() uses the low level windows api:
