delete folder/files and subfolder

Question

I want to delete a folder containing files and a subfolder, also containing files. I have used everything, but it is not working for me. I'm using the following function in my web-application asp.net:

var dir = new DirectoryInfo(folder_path);
dir.Delete(true); 

Sometimes it deletes a folder, or sometimes it doesn't. If a subfolder contains a file, it only deletes the file, and not the folder as well.

Answer 1

Directory.Delete(folder_path, recursive: true);

would also get you the desired result and a lot easier to catch errors.

Answer 2

This looks about right: http://www.ceveni.com/2008/03/delete-files-in-folder-and-subfolders.html

//to call the below method
EmptyFolder(new DirectoryInfo(@"C:\your Path"))


using System.IO; // dont forget to use this header

//Method to delete all files in the folder and subfolders

private void EmptyFolder(DirectoryInfo directoryInfo)
{
    foreach (FileInfo file in directoryInfo.GetFiles())
    {       
       file.Delete();
     }

    foreach (DirectoryInfo subfolder in directoryInfo.GetDirectories())
    {
      EmptyFolder(subfolder);
    }
}
