Why doesnt this work???

this is a recursive routine to delete empty sub directories under a given path.

private void DeleteEmpty(string aPath)
{
string currPath = System.Environment.CurrentDirectory;
System.Environment.CurrentDirectory = aPath;
string[] directory = Directory.GetDirectories(".");
string[] file = Directory.GetFiles(".");
if ((file.Length + directory.Length)==0)
{
System.Environment.CurrentDirectory = currPath;
Directory.Delete(aPath);
}
else
if (directory.Length>0) 
 for(int i = 0; i < directory.Length; i++)
	DeleteEmpty(directory[i]);
else
System.Environment.CurrentDirectory = currPath;
}

 

Directory.Delete(Path.GetFileName(aPath))

gives error:

An unhandled exception of type 'System.IO.IOException' occurred in mscorlib.dll

Additional information: Access to the path "C:\Practice\Sub1" is denied.

I have the directory structure:

C:\Practice

|_ Sub1

 

I make a call DeleteEmpty("C:\Practice");

Sub1 is empty.

There is no process locking the path. While In debugging, I can manually delete the folder while the error message is up.

any ideas????

Just tried it on my PC here and it worked without any problems. Also rather than switching the current directory back and forth (which may be causing a problem) try the following snippet

 

private void DeleteEmpty(string aPath)
{
string[] directory = Directory.GetDirectories(aPath);
string[] file = Directory.GetFiles(aPath);
if ((file.Length + directory.Length)==0)
{
	Directory.Delete(aPath);
}
else
	if (directory.Length>0)
       	for(int i = 0; i < directory.Length; i++)
		DeleteEmpty(directory[i]);
     }

well the purpose of this was part of a routine for a little utility I wrote that was organizing my mp3/wma collection by artistsortorder/albumsortorder ala

 

\Music

->\Artist1

->->\Album1

->->\Album2

->\Artist2

->->\Album1

 

I ran into problems working with with paths that exceed max path length, like

 

"D:\Music\A Silver Mt Zion\He Has Left Us Alone But Shafts of Light Sometimes Grace the Corners of Our Rooms\A Silver Mt Zion - He Has Left Us Alone But Shafts of Light Sometimes Grace the Corners of Our Rooms - 13 Angles Standing Guard 'Round the Side of Your Bed.mpg"

 

I tried using the workaround suggested from MS but that didnt seem to work.

By using relative paths I got around it while moving files. Its not as much an issue when clearing directories. . .

 

Let me try your code. I might need to reboot, too. I installed the WMP 10 sdk and am working with that. could be a bug there.

 

thanks
