C # Ftphelper supports multi-level file upload and download

Find a lot of code on the Internet always feel unable to meet the existing needs, such as multi-level folders, one-time upload all the files at different levels. Add your own changes to the code you find online. Now posted out to everyone hope that a little help to everyone. Welcome to the fault, progress with each other
