A similar dynamic segmentation of IDM downloader to download

With c #

Assumptions have eight threads run at the same time, the file block to eight thread download (range), the eight thread download assume some download fast download some slow, when a thread download is completed, the thread is idle down

The idle thread will get other threads to download the remaining amount (has A threshold value, such as other documents also in the download as A thread block also need to download the surplus is greater than 200 k), fits the setting of threshold value after the idle thread will get half of the 200 k download, originally A thread end download subscript adjustment at the same time;

Q: what's the idle thread for other threads are downloading and threshold adjustment after the subscript, idle thread and continue to download?
