delete empty folders in a directory

I am trying to delete all of the empty directories in a directory. I have code that works:

        private static void processDirectory(string startLocation)
        {
            foreach (var directory in Directory.GetDirectories(startLocation))
            {
                processDirectory(directory);
                if (Directory.GetFiles(directory).Length == 0 && Directory.GetDirectories(directory).Length == 0)
                {
                    Directory.Delete(directory, false);
                    log.Rows.Add(DateTime.Now, "Success", "The directory named " + directory + " was deleted because it was empty.");
                }
            }
        }

Open in new window

which works good other than the line about adding the row to the log will not work because it is out of the context.

I tried putting this block of code into the main part of the code, but it will not work.

ideas?

Thanks.

Hi, try this

using System;
using System.IO;

class Test
{

public static void Main()
{
// Specify the directories you want to manipulate.
string path = @"c:\MyDir";
string subPath = @"c:\MyDir\temp";

try
{
// Determine whether the directory exists.
if (!Directory.Exists(path))
{
// Create the directory.
Directory.CreateDirectory(path);
}

if (!Directory.Exists(subPath))
{
// Create the directory.
Directory.CreateDirectory(subPath);
}

// This will succeed because subdirectories are being deleted.
Console.WriteLine("I am about to attempt to delete {0}", path);
if(Directory.ContentLength >0)
{
Directory.Delete(path, true);
Console.WriteLine("The Delete operation was successful.");
}

}
catch (Exception e)
{
Console.WriteLine("The process failed: {0}", e.ToString());
}
finally {}
}
}

If you are talking about the current context of a web page you could pass it into the static method by adding a parameter HttpContext currentContext and proving HttpContext.Current when you invoke the method. Otherwise, you could pass a reference to the log when you call the static method - that would allow you to update it.

samirbhogayta,

This will not work at all. It is not addressing any of the issues that I am working with. I do not know the names of the sub directories, and don't need to. I just need to delete them if they are empty. I do not want to write any lines of text to the console, I need to add rows to a table. I have read the text you posted on other web pages. It is not what I am looking for.

MajorBigDeal,

It is not dealing with a web page. It is not is the same context because the method that I posted is outside of the context of the main method which has the log table in it.
