Implementation of batch download tool based on C # Baidu image

don't have a net at home, how to be bored? It's better to look at some beautiful pictures, the network is fast batch download, there is time to look slowly, hey, I am a good person. So the implementation of this tool, it is almost imminent ah, to see how the realization of it.

First piece bar:

This is the WinForm interface of the software, based on the C # implementation.
On the code, there are more than 100 lines.
