Delete a directory from Isolated storage windows phone 7

Question

I created a directory named "MyFolder" and wrote some text files there. Now, I want delete that directory and I am using the following code:

 public void DeleteDirectory(string directoryName)
        {
            try
            {
                using (IsolatedStorageFile currentIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
                {
                    if (!string.IsNullOrEmpty(directoryName) && currentIsolatedStorage.DirectoryExists(directoryName))
                    {
                        currentIsolatedStorage.DeleteDirectory(directoryName);
                        textBox1.Text = "deleted"; 
                    }
                }
            }
            catch (Exception ex)
            {
                // do something with exception
            }
        }

I tried with

DeleteDirectory("MyFolder") 
DeleteDirectory("IsolatedStore\\MyFolder")

however it didn't delete that directory. Any idea to solve that?

did you delete everything in it first? i'm not sure that is required... but it might be? — John Gardner

Have you deleted all of the contents of that directory?

http://msdn.microsoft.com/en-us/library/system.io.isolatedstorage.isolatedstoragefile.deletedirectory(v=vs.80).aspx

says (although it isn't the windows phone version of the documentation):

A directory must be empty before it is deleted. The deleted directory cannot be recovered once deleted.

The Deleting Files and Directories example demonstrates the use of the DeleteDirectory method.
