问题 Background Info: I have a program running through a list of url; each URL is to be downloaded one at a time but ran in a background thread to maintain UI responsiveness. In order to report progress, I'm using the DownloadFileAsync method. My problem is that I would like to be able to have a cancel button that would immediately end the download.

问题 Aight, before I get redirected to some post that doesn't answer this. I would like to state that I am creating a program AUTO UPDATER.
