Directory.Delete（path，true）删除所有文件和子目录，但引发异常

Question

I use Directory.Delete(path,true) method to delete a directory. Before deleting, I use this method to check if the folder could be deleted:

private bool FileCanDelete(string path)
    {
        try
        {
            //if this does not throw exception then the file is not use by another program
            using (FileStream fileStream = File.OpenWrite(path))
            {
                if (fileStream == null)
                    return false;
            }
            return true;
        }
        catch (UnauthorizedAccessException uaex)
        {
            throw uaex;
        }
        catch
        {
            return false;
        }
    }

If the return result is true, call the delete method. I can see all the files and subdirectories have already deleted, but the method throw an exception, "The process cannot access the file 'xxxxxxx'".

If the whole folder couldn't be deleted, I want the delete operation doesn't delete any file in the folder.

Try using .NET Transactional File Manager

TxFileManager fileMgr = new TxFileManager();
using (TransactionScope scope1 = new TransactionScope())
{

    fileMgr.DeleteDirectory(path);
    scope1.Complete();
}
