Question

I am trying to delete the folder created in isolated storage.
But i get a error of “path must be a valid file name”
My created file name is “a07292011//time.Schedule”.

So now i want to delete the folder and my code is:

myStore.DeleteDirectory(selectedFolderName1 + “\\”);

Where selectedFolderName1 = a07292011

    public static void DeleteDirectory(string directoryName)
    {
        try
        {
            using (IsolatedStorageFile currentIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
            {
                if (!string.IsNullOrEmpty(directoryName) && currentIsolatedStorage.DirectoryExists(directoryName))
                {
                    currentIsolatedStorage.DeleteDirectory(directoryName);
                }
            }
        }

        {
            // do something with exception
